When we talk about geotourism, the first thing that comes to mind are beaches, forests, deserts, mountains, underground wells, hot springs and areas of dormant volcanoes. But Saudi Arabia is also full of monuments and caves,” Mohammed told Arab News.

 

Geotourism is starting to revive in the Kingdom, and travelers of all ages are discovering that caves are a safe and enjoyable source of adventure.

 

According to the guide, caves in Saudi Arabia are divided into five basic types according to their geological division: Ice caves, which are formed in ice in cold regions; marine caves formed by waves, oceans or rivers flowing into large rocks or mountains, creating large cavities over thousands of years; basaltic caves, known as volcanic caves; limestone caves; and sand caves that form inside sandy mountains.

 

The cave, a long tunnel formed by volcanic lava, was formed when the surface of the volcanic lava began to freeze, with the lava below ground remaining as liquid due to the high temperature.
