The Tourists Guide To The 10 Amazing Volcanoes in Saudi Arabia


You would be astounded to know that Saudi Arabia has more than 2,000 volcanoes in the Western province. In addition, there are huge 12 lava fields called Harrats. They run north to south of the kingdom along the Red Sea coast. 

Harrat: Arabic for a large area of rocky, stony terrain of volcano field

They take up more than 80,000 sq km of space and run in a long chain starting in Syria/Jordan in the north down the entire length of the western region of Saudi Arabia ending in Yemen in the south.  

There are many amazing caves too. They can be found mostly in the limestone regions of the north and east of the kingdom. They were formed during an era when the Saudi climate was very wet. 

Though the kingdom has many volcanoes, it has fewer (as yet) known caves. Those that have been discovered can be found in the high coral limestone regions along the Red Sea coast and on the huge basalt lava fields.

After volcanic eruptions, huge, long lava tubes formed to carry molten lava away. As the lava slowly oozed down the side of the volcano, the molten lava gradually disappeared from the lava tubes and left many of them empty.

Today, they can be seen as amazing deep caves ready for exploration. 

Example of Lava Tubes at Harrat Al Kisbh, North East of Taif

Over the centuries, most of the 2,000 volcanoes in Saudi Arabia erupted and produced lava tubes including underground caves. Some of those caves have been discovered. Many though have not. It is still possible that hundreds more still exist below the ground waiting to be found. Only time will tell.

What Is A Volcano?

A volcano is a big hole in the earth from which hot magma (liquid rock) and melted rock, ash, cinders and dissolved gas escape during a volcanic eruption. 

Strombolian Blast Sarychev Volcano 2009 Courtesy WikipediaOpens in a new tab.

Some explosions (Strombolian blasts) are violent and dramatic. They send ash, rock fragments including bombs of lava hurling high into the air. 

Others are low-level eruptions (Hawaiian flows) where thick hot magma (500°C to 1,170 °C) bubble and fizz out of ground vents but produce very little ash or gas.  

Hawaiian Eruption Courtesy WikipediaOpens in a new tab.

Over time, on a flat volcanic area or field, large mountains or hills take form out of solidified lava and ash. Their shape and height depend on the structure of the earth’s crust, the type of hole, the nature and amount of magma that is discharged, the temperature, pressure, water content and the way that molten lava falls and solidifies around the hole.  

Generally, there are three types of volcano:

  1. Active – Recent and Future Eruptions Possible
  2. Dormant – No Recent Eruptions but Future Eruptions Possible
  3. Extinct – Eruptions Are No Longer Possible

Why Does Magma Escape Out Of The Earth’s Crust?

The image above shows the arching fountain of a Pahoehoe shooting up about 10 m high. It comes out of the west of 0740 which is a chain of vents, spatter cones measuring 170 m long, located south of Pu‘u Kahaualea.E Courtesy Wikipedia

Magma is made when very high temperatures cause the earth’s lower crust or its mantle to melt. This magma and the dissolved gases it contains escape through a vent or opening in the earth’s surface. 

There are four main causes of volcanic eruptions: 

  1. The Lightness of The Magma
  2. The Pressure of Gasses in The Magma
  3. New Magma Forced Into An Already Full Magma Chamber
  4. Shifting Tectonic Plates

The Lightness of The Magma

Due to its lightness, magma rises to the earth’s surface. It does this because as rocks melt deep within the earth, its mass stays the same but the melted rock increases in volume. During this process, it becomes less dense than the rocks which surround it and naturally rises to the earth’s surface. 

The Pressure Of Gasses In The Magma  

Before magma rises to the earth’s surface, the dissolved water in the magma is at about 5% saturation. As it rises, excess water separates from the magma due to its decreasing solubility and bubbles are formed. 

This exiting water causes the ratio of gas to magma to ever increase. When the bubbles get to 75%, the magma then becomes pyroclastic, (fragments) resulting in fountains or spatters of explosive blobs of molten lava to be ejected into the air at the surface. 

New Magma Forced Into An Already Full Magma Chamber

Hot magma is forced to the earth’s surface through the conduit (tunnel) because new magma squeezes into an already full magma chamber. The intense pressure causes the magma to rise and an eruption to occur at the surface.  

Shifting Tectonic Plates

The above map shows 15 of the biggest tectonic plates. The lithosphere is a plate that exists separately and which floats of a fluid sea (visco-elastic) of the asthenosphere. This fluidity allows the tectonic plates to move in various directions. Courtesy of Wikipedia.

Plates Move Away

When the tectonic plates in the earth’s crust move away from each other, a gap is produced and magma rises from deep within the earth to take up space. This results in volcanoes under the sea.

Plates Move Together

When the same tectonic plates move against each other, the earth’s crust is forced downwards. This movement deep into the earth at high pressure and at a high temperature causes the crust to melt and for the magma to rise. 

Hot Spots

From deep inside the earth, a thermal plume (featherlike) melts rocks under the tectonic plates (lithosphere). The resulting magma rises through gaps in the earth in eruptions to eventually form volcanoes.

  • Qummatain  (Twin Peaks)
  • Djar’tain       (Two Levels)
  • Ukhwatain      (Two Brothers)

There are also hot springs located between Qummatain and Dajar’tain, Ukwatain. Jabal Yar erupted in 1810 or thereabouts with a small eruption with lava flows. It is still considered to be active and historically it is the only one in Saudi Arabia. 

Directions to Jabal Yar

1. Jabal Yar Volcano Field Location

Jabal Yar can be found by driving northeast out of Jizan City for 30 km on route 140. When you get to the small town of Abu Arish, there are two small cones about 7km south of the town on Route 1570 road right opposite the Al Hasma Housing compound in the direction of Al Wahma

The remaining long line of cones lies 8 km north of the small town of Abu Arish on Route 156 or alternatively on route 1556, but its more difficult. 

Drive on Route 156 towards the huge Jizan Wadi Dam.  2 km after reaching the Jizan Military Hospital and before you get to the dam, take a left and drive north to towards the large housing compound. 

Opposite the housing compound, you will see the first (huge) scoria cone on your right. Turn left off the road and drive around the first scoria and instead of driving towards Al Saad Park next to the dam, take another left off-road to head to the area north of the Jizan dam

You will see a large rectangular walled enclosure on your left. You can miss it. After another 3-4 km, there are three more huge cones on your left after about you pass the Umm Al Marniq School on your right.

To get around the scoria cones you can walk or go off-road at this point.

Harrat Al Kishb is a basaltic volcano field that contains maars, scoria (cinder) cones, tuff rings, lava flows, and domes. 

 It is located 300 km northeast of the city of Mecca

It originated during the Pleistocene era between 2,580 and 0.12 million years ago. The lava flows you can see there are from the Holocene period and are about 12,000 years old from a time when the glaciers disappeared. They are located in the Western half of the field. 

Al Kishb has the following features:

5 Explored Prominences and 1 Giant Crater

  1. Jabal Aslaj is a scoria cone with lava flows that contain granite clocks. 
  2. Jabal Hil is a prominent scoria cone that has an impressive huge crater that got filled up with lava and eventually covered with water to become a lake.
  3. Jabal Zuwayr has a whaleback hump.
  4. Jabal Abu Haris is a tuff ring.
  5. Jabal Shalman has a lava dome, flows, and scoria conical shape that are about 6,000 years old. 
  6. Seven Volcanoes
Al Wahba Crater (Maar0 at Harrat Al Kisbh

Al Wabah Maar (crater) is massive nearly 2 kilometers wide and just less than 1 kilometer deep and is located in the west of the field.  

You can drive to the crater entrance at Maqla Tamiyah. There are toilets and a small visitor center there. You can descend in return to your car in about 1 hour. The path is rocky and slippery underfoot when wet. Take care!.

Lava Tube Caves 

Around the field, there are also some wonderful caves that people visit and climb about inside. In fact, they are lava tubes. There are 6 in total located in three separate areas in Hafir Al Kishb

  1. First Shaft Cave
  2. Kahf Al As Shabbah  (Kahf=Cave Shabbah=Ghost) 
  3. Kahf Bushy

The Caves of Al Kishb

The Lava Tube Caves at Harrat Al Kisbh

The biggest and the longest lava tube is located to the west of the scoria cone of Jabal Hil. It erupted thousands of years ago. After the eruption, the lava tube drained and it collapsed. You can still see inside the inner tube which is over 20 m high and goes down 42.5 km below the ground level. 

The First Cave can be seen from above down a dangerous loose rocked 26.5 m shaft. Take care!  

In the East of the field, the second is the largest called Kahaf Al Shabah (Ghost Cave) has two main tubes measuring 140 m and 143 m. 

There are also two smaller caves nearby called Kahf Bushy and Al Mutaeb. Close by there is a single erosion cave called the Window Cave which is only 1 m deep.

The sixth cave is called Kahf Dahl Faisal. It is located close to Jabal Hil in the basalt north of the field. It is 22m long. 

The lava tube caves are elliptical (egg-shaped) in shape and contain lava stalactites on the ceiling and lava levees (edges or prominences) on the walls.  These tube caves are half-filled with sand washed in by the rain and dust from the wind.

4. Harrat Al Rahat between Taif and Madinah

Harrat Al Rahat is easily the biggest volcano field in all of Saudi Arabia. It starts just 10 km south of the city of Madinah and extends 300 km south to approximately 70km from the northern boundaries of the city of Taif. It is between 60 and 80 km wide at various points. 

There are six-seven lava flows, four massive ones measuring 100 km wide and much of the activity is in the northern part of the field. The huge long vent which produced the flows runs north, northwest. The field consists of tens of scoria cones. It also has shield volcanoes and domes that were produced from pyroclastic flows and surge deposits.  

The tens of scoria cones and rings align almost perfectly along one huge vent running North to South for the whole 300 km distance from Madinah to Taif. 

Harrat Al Rahat
Ciner Cones at the Harrat Al Rahat

Harrat Al Rahat last erupted in 1256 AD from out of six scoria cones. The resulting  500 million m3 lava flows reached to within 23 km of the city of Madinah. You can still see them today. 

The nearest lava flows can be seen from the city at the King Khalid Ring Road opposite the Taibah University College and Taibah University College. In fact, there are 10 separate flows reaching almost to the city in a huge spider-like formation.  

The most impressive cluster of scoria cones and shield volcanoes can be seen 35 km southeast of the city of Madinah out on the Ali Ibn Abi Talib Road

Directions To Harrat Al Rahat

Start your trip from the center of Madinah at the Main Hospital and Maternity Hospital. They are right at the start of Ali Ibn Abi Talib Road. Drive out of the city crossing the King Khalid Ring Road. Continue until you reach the vehicle inspection point which covers the road. After 25 km you will begin to see more of the massive lava field both right and left of the road and small tuff rings will appear. 

Continue until 32 km and you will see a mosque (Masjid Al Thamaani) on your right and the first scoria cone behind it. Beyond this, there are many more features besides. 

From the mosque, you can drive up the first dome to see the view of the other shields and cones behind it. There is an exit onto the volcano field on your right just 1 km before you get to the mosque.

Harrat Al Lunayyir volcano is a basaltic field located on the Red Sea coast of Saudi Arabia the entrance of which is 85 km east of the beautiful town of Umluj. 

The field is worth a visit and it contains the following features: 

  • 50 Scoria/Cinder Cones
  • Lava Flows Running North-South
  • 2 Lava Flows Reach The Sea

Al Lunyyir Earthquake

Magma Wall below the fissure came within 1 kilometer of the surface at Harrat Al Lunayyir
Courtesy Kaust

It erupted before the year 1000 AD. On 19th May 2009, 31 earthquakes (seismic swarm) occurred reaching a 5.7 magnitude. It made cracks and fissures in the ground. 2,889 people were evacuated to Yanbu City from an area of 20 km around the volcano including 326 families. Because of the earthquake, it is Al Lunayyir could now be volcanically active. The evacuees returned home in August 2009 after the all-clear was given. 

Al Lunayyir was supposed to be inactive, due to its position on the borders of the continental rift, 200 km away from the active center beneath the Red Sea. As the continental plates pull apart, magma shoots up to fill in empty space. But, because of the fact that they are under the sea, they cannot be easily studied.  

Read the Kaust Article about Wall of Magma and the widening fissure at Harrat Al LunayyirOpens in a new tab..

One of the fissures measuring 3 km opened up to 8 km wide during the swarm quakes. Radar satellite pictures determined that magma has likely entered the widening rift and reached a shallow 2km deep an area of 10 km along the fissure. 

As a result, scientists are on the alert for further quakes or seismic activity. 

Directions To Harrat Al Lunayyir

The Al Lunyyir volcano lies 500 km north of Jeddah. To get there, drive north from Jeddah to Umluj on National Route 50. From Umluj town center, turn right at the Al Hawra hospital roundabout onto King Saud road. Drive east and continue on the King Saud road called Route 888. 

Harrat Al Lunayyir

Harrat As Shabahah

Harrat Shabahah Sheild and Cones

Follow Route 88 for 60 km and you will arrive a small cluster of scorias called Harrat Al Shabahah. They lie to the left (2) and right (10) of the Botanical Gardens just before the gas station.  

Drive now until you arrive at the village of Al Fera after 25 km. About 10 km before arriving at Al Fera, look to your right and you will see another small cluster of six cinder cones and a beautiful small maar on your left.

As you enter Al Fera, you will see a bakery on your left and a mosque on your right. The entrance to the remaining volcano field is directly after the bakery on the left. Turn left and have fun exploring.

You can access another northerly series of cones from the village of Al Qurash which is 25 km due north of Al Fera on Route 888. When you arrive at Al Qurash gas station you will see an Al Rahji ATM on your right. Now, turn left onto the Al Marameh mountain road. 

After 4 km on the Al Marameh mountain road, you need to turn left just after the massive black lava flow so as to reach the scoria zone which is about a further 35 km due west into the field. 

It is a long road, and you will know you have arrived because before you get the scoria cones, you find a grocery store on your left and a small mosque on your right. 

Drive a little further past the store and you will arrive at another black lava flow. Continue for another 15km until you reach 10 more scorias at the Harrat Al Lunayyir.

Harrat Al Khaybar is a massive basaltic volcanic field that is a 100 km long line of landform running North to South containing vents, scoria cones, lava domes, mars and lava flows. It has Saudi Arabia’s only known stratovolcano called Jabal Qidr. It lies directly north of the city of Madinah, Saudi Arabia. 

Jabal Baydha, Medinah

In the last 1,500 years, there have been 8 lava flows. One which flowed out of Jabal Qidr now extends for 55km. The last eruption occurred 1,400 years ago.   

Al Khaybar borders the Ithnayn field (North) and the Kura field (West) in one giant uninterrupted area of basaltic lava fields measuring 20,564 sq km. 

The entire field contains the following features:

  • 327 Scoria Cones
  • 46 Shield Volcanoes
  • 20 Domes
  • 5 Tuff Cones
  • 1 Stratovolcano
  • 30 Whaleback lava flows.
  • White Lava Flows made of Comendite
  • 400 Ancient Stone Works

Lava Flows

Lava flows from the three Harrats converge and overlap. These 5 million-year-old lava flows are particularly impressive for visitors who love a walk on them and stand astride the boundary where the black and white flows meet to take selfies. 

Ancient Gates

Ancient Gate Discovered by Australian Professor

Also, in 2017, a Professor from the University of Western Australia using satellite imagery (Google Earth) discovered 400 mysterious stone structures thousands of years old. To date, no one knows what they were used for.   

Click here to read Arab News articleOpens in a new tab. related to the discovery of the ancient gates in Harrat Al Khaybar

They are called gates because they appear like fallen field gates on the satellite imagery. Some are small about 13 m long whereas others are huge about 500 m across about being four times the size of a football pitch. 

They were built on ancient lava domes and some go up to their sides. Some have lava flow over them so they predate some volcanic eruptions. The gates are low, roughly made and about 7-9,000 years old. 

Directions To Harrat Al Khaybar 

Jabal Qadir, MAdinah

Starting at the City of Madinah, drive due North West on the National Route 15 for 155 km until you reach the town of Al Thamad. 

Before you reach the volcanoes, it is worth visiting the old fort town of Khaybar 16 km north of Al Thamad.  It is an ancient oasis stopover, once inhabited by Jews and retaken by Muslims in 629 AD. Most of it is in ruins.

Drive through Al Thamad until you reach the gas station (3 km). It has a little painted red and yellow mosque, a small hostel, shops, and petrol supplies.

At the petrol station, take a right and drive for 45 km until you reach the volcano field.  

You will pass a Shisha/Coffee House on your left, then the Bin Mitran Mosque on your right after about 5 km. You will arrive at Rahbat Al Hosni village after a further 15km. From Rahbat, drive for another 5km. There you will start to enter the black mountainous landscape. 

Drive north for another 20 km and you will begin to see the volcano field. There is a sign on your right for the direction to Umm Jirsan Cave. Here you can enter the volcano field on your right. It is off-road so you need a good SUV or high wheel based vehicle. 

Click here to read an Arab News article about Saudi women taking up caving as a hobby in The woman unlocking mysteries of Saudi Arabia’s caves.

After you enter the volcano field and you must drive for 10km more. On your right, you will find Umm Jirsan Cave opposite the large volcanic mound.

If you don’t want to visit the Umm Jirsan Cave, continue north on this route for a further 26 km. It will take you directly to the Black and White Volanco lava fields. When you arrive, stop your vehicle and start exploring.  

In addition to the Black and White volcano, you can walk and visit as many of the tens of cones, shields, and tuffs that make up the massive lava field. 

It is exhausting but worth it. Also, consider a tour or going with an experienced guide who knows the terrain well.

Harrat Al Ithnayn fields are basalt. They consist of about 20 vents but they are lined up a little more crookedly than other Harrats in Saudi Arabia. There are scoria cones and some small tuffs. They lie in an area of about 60 sq km, 200 km southwest of the city of Ha’il in Saudi Arabia. 

Harrat Al Ithnanyn 160 km southwest of Hail, Northern Saudi Arabia

The field is great and popular with campers and cave explorers. It has the following features: 

  • 20 Scoria Cones and Tuff
  • 1 Huge and Smaller Craters
  • Spawling Lava Flows 
  • Many Lava Tubes and Caves
  • Rock Art
  • Thermal Vents

The solidified lava flows are made up of basaltic rocks, but unlike the neighboring Harrat Al Khaybar, they do not contain silicon. 

The Ithnayn field (North) joins with Harrat Al Khaybar to the south, the Kura field (West), and Harrat Rahat (Immediately South of Al Khaybar) in one giant uninterrupted area of basaltic lava fields measuring 20,564 sq km. 

There are numerous caves that are lava tubes. The longest is Kahf A Shuwais (530 m). Two more well-known caves are located at the base of the Hazim Al Khadra volcano. Some caves feel very warm due to thermal activity from fumaroles originating in other shelter caves. 

Eyewitness local bedouins have reported that they can see smoke-like vapor emanating from the vents of Harrat Al Al Ithnayn.

  • Many Scoria Cones and Tuff
  • Spawling Lava Flows 
  • Gorges
  • Oasis 
  • Rock Art
  • Magical Towering Landscape
  • Ancient Sites
  • Camp Sites
  • Hostels
  • Great Off-Road Driving

The field consists of masses of raised lava flows running northeasterly direction. It is about 37 km at its widest and 3 kilometers at its narrowest point.  

Viewed from the Red Sea town of Al Duba is rises up by an impressive 550 m above the Cambrian sandstone plain. The eruptions that occurred many years ago came about from a fissure in the crust. So, you will see a long line of amazing scoria cones and tuff cones stretching from North to South for about 80-125 km along an escarpment.  

Al Disah Oasis & Gorge– Nature Sanctuary

The Stunning Al Disah Oasis Harrat Al Rahah (Wadi Qirqir)

Al Disah is an outstandingly beautiful cushioned in a long stretch of sand. The oasis is surrounded by towering sandstone escarpments and breathtaking peaks. It looks like a lunar landscape in a sci fie movie. 

It is a magical-looking place. To reach there drive up the Wadi Qirqir river bed, lined with gushing freshwater springs and date palm trees and greenery on each side until you reach a deep gorge area with high cliffs on each side. 

Dry in the summer, but usually gushing freshwater runs down its center in the colder months.  

Now get out of the car and take time to explore. Climb up the conical sandstone rock cliff faces rising up above you. 

Discover the ancient tombs hidden high up the cliff walls and witness the ancient petroglyphic artwork of human and animal figures (camel, ostrich, and antelope) known to be thousands of years old. It is delightful.

Further, into the village, there is a Nabataean tomb that is sometimes open and you can visit it. 

Directions To Harrat Al Rahah

It is a 4-hour drive north of Umluj. Start your trip at Duba. First, turn right at the roundabout onto Route 80 at the Seville Stadium. It is the main route to the city of Tabuk. You will see Duba Plaza, City Max and Herfy’s on you right as you enter Route 80.

Harrat Harrah (Saudi Sharmah) Crosses Syria, Jordan, and Northern Saudi Arabia

Harrat Al Shamah is the Saudi Arabian portion of a huge basaltic volcano field called Al Harrah that is located in the North-Western part of Saudi Arabia. It starts in Syria and extends through Jordan and onto Northern Saudi Arabia. 

It is a landscape of rising and falling basalt lava fields, entirely made up of gravel plains and wadis (valleys) with scarce vegetation. 

It runs for 210 km from the northwest to the southeast and is about 70 km wide traversing the banks of the Wadi (River Valley) Sirhan.

Harrat Al Shamah has:

  • Huge Plain Expanses
  • Basaltic Lava  Flows
  • Cinder Cones
  • Tuff Rings
  • Shield Volcanoes
  • Areas for Nature Conservation
  • Arabian Leopard Reserve

 At its highest point, the field rises to 1,100 m at Jabal Amud (Pillar Mountain).  

Moon Like Gravelly Plains fo Harrat Sharmah

Harrat Al Shamah first took shape as a result of volcanic activity during the Oligocene (65-23 million years ago) and Quaternary (2.6 million ago) eras. 

The first eruptions began at the southeastern part of the field in the Miocene period 1-14 million years ago. Further eruptions then occurred in the late Pleistocene era about 0.126-.012 million years ago. 

During the periods between eruptions, sands blew onto the fields lava and today lava and sand are layered. Today, it is dormant, but eruptions also occurred a few hundred years ago and are likely to happen again. 

Volcanic eruptions took place along long fissures. It also has grabens and fractures.  

Since 1987, the Harrat Al Harrah has been designated as a Special Nature Reserve by the Saudi Wildlife Authority today known as the King Salman Nature Reserve.
