What is the largest dune in Liwa?

Overview of Liwa and Its Dunes

Liwa is an oasis area located in the desert in the western region of Abu Dhabi. It is known for its beautiful yet imposing golden sand dunes, which have formed over thousands of years due to the area’s wind and weather conditions. Some key things to know about the Liwa dunes:

  • The dunes cover an area of over 22,000 square kilometers.
  • Some dunes in Liwa reach heights of over 300 meters (over 980 feet), equivalent to around 100-story skyscrapers.
  • The dunes are part of the larger Rub’ al Khali desert, the largest contiguous sand desert in the world spanning parts of Saudi Arabia, Oman, Yemen, and the UAE.
  • The shapes and locations of the dunes are continually changing as winds reshape the sands. Old dunes disappear and new ones form.

Tal Moreeb – The Tallest Dune

The tallest sand dune in Liwa is Tal Moreeb, also referred to as Al Moreeb Dune or Moreeb Hill. Some key facts about Tal Moreeb:

  • Height: Tal Moreeb rises to a height of about 300 meters (984 feet), making it almost as tall as the Eiffel Tower in Paris.
  • Slope angle: The windward slope has an incredibly steep 50-degree angle.
  • Color: The dune exhibits a reddish-orange hue due to an underlying layer of red sand that peeks through the overlaying layers of yellowish sand.
  • Changing shape: Tal Moreeb’s shape transforms seasonally and annually as winds shift sands across its peak. The dune moves southwesterly at an average rate of 1 meter per year.
  • Activities: Going on a dune drive to traverse Tal Moreeb’s imposing face is a popular desert activity. Camel trekking expeditions scaling the dune are also common. At the top, visitors are rewarded with phenomenal panoramas of the sea of surrounding dunes.

Dune Composition

The sand that makes up Tal Moreeb and Liwa’s other dunes originates from sediments carried over millions of years into the Rub’ Al Khali basin by rivers flowing east from Africa’s Ethiopian Highlands. These wind-blown sediments accumulated in the basin to depths exceeding 1,000 feet to form today’s expansive sand desert.

The dunes themselves consist of distinct layers:

  • Surface layer: The top layer comprises dry loose sand grains shuffled by persistent winds.
  • Aeolian sand deposits: Underneath lies sand bound together by moisture to form harder accumulations.
  • Red silicified sand: Beneath this is a layer of red sand cemented into sandstone over 65 million years ago. This dense ancient layer occasionally peeks through to the surface to color some dunes reddish-orange.
  • Ancient riverbed gravel deposits: The lowest strata are gravels deposited by ancient river systems that once flowed through the area. These define the basement on which all the sand layers accumulated.

What causes the shape and size of the Liwa dunes?

The impressive shape and scale of the Liwa dunes like Tal Moreeb are influenced by several geographic factors:

Wind Strength and Direction

  • The powerful prevailing winds in the region, driven by different wind regimes depending on the season, blow large quantities of sand northeastwards. This transports sediment that gradually accumulates into enormous dunes.

Sand Supply

  • There are rich sources of sand all around Liwa, supplied by the surrounding sands of the vast Rub’ al Khali desert. This feeds the growth of the dunes.

Flat Surface

  • The relatively flat plain provides an ideal platform for dunes to advance across. Without obstacles in their path, the dunes can migrate freely.

Moisture Effects

  • Subtle humidity from the nearby Persian Gulf and intermittent rainfall cause moisture differences within dunes. This makes layers within Tal Moreeb and other dunes more prone to erosion, influencing their shapes.

Changing Winds

  • The dunes change shape seasonally and annually as they slowly advance northeastwards, driven by winds periodically shifting direction.

How do people visit and traverse the Liwa dunes?

Visitors to Liwa seeking to experience its magnificent dunes first-hand typically embark on popular pastimes such as dune driving, dune bashing, sandboarding and camel trekking:

Dune Driving

  • Special 4×4 vehicles with rugged tires drive enthusiasts up and over the dunes, including to the peak of Tal Moreeb.
  • Drivers require skill to traverse the ultra-steep dune faces without flipping or getting stuck.

Dune Bashing

  • Dune bashing involves driving 4x4s at speed up and down the dunes’ slopes while sharply turning and spinning through the sands.
  • This adrenaline-fueled activity allows riders to experience the extreme terrain.


  • Adventure seekers slide down the towering dune faces on sandboards, gaining tremendous speeds.
  • It’s considered safer than snowboarding given the soft landing on sand.

Camel Trekking

  • Visitors can saddle up camels for multi-day trekking tours marching through the desert and climbing to the summits of dunes like Tal Moreeb.
  • Camel rides provide a traditional Bedouin method to experience the desert terrain.

Safety is paramount for all desert activities – drivers and guides must have proper training and credentials. With the proper precautions, traversing Liwa’s massive dunes can create adventurous memories that last a lifetime.

When is the best time of day and year to see the Liwa dunes?

The lighting and coloration of the Liwa dunes shift beautifully throughout the day and in different seasons. Here is an overview of the best times to view the dunes:

Time of Day

Early morning and late afternoon tend to provide the most visually stunning light:

  • Sunrise/sunset: Low angle light at dawn and dusk casts long shadows and intensely illuminates the dunes in warm golden hues.
  • Mid-day: Harsh overhead sunlight tends to bleach out some of the coloration.

Time of Year

The shifting seasons also impact the dunes’ appearance:

  • Spring: In March/April, strong winds reshape the crests, revealing more reddish sands that color the dunes vividly.
  • Summer: Late May to August brings hazy horizons obscuring views and very hot temperatures making mid-day visits unbearable.
  • Fall: September through November offer clear skies providing crisp views. Dune driving adventures peak during this popular time of year.
  • Winter: December to February brings occasional rains that add lush greenery at the dunes’ bases and to the nearby oases contrasting beautifully with amber sands.

So for the best experience, visitors should aim for sunrise/sunset tours in the fall or winter months. But the dunes offer stunning vistas year-round at different times, revealing their ever-changing nature.
