Jabal Qarah or Qarah hills are made up of sedimentary rocks like sandstones and limestone.

Jabal Qarah is a flat-topped hill with a maximum elevation of 225 meters above sea level. By the passage of time, water and wind transformed this hill into an abode of caves and fascinating landscape.

Hills around Jabal Qarah have amusing shapes, sizes and, of course, color. Morning and evening provide best time for a photographer to sketch this landscape. 

Why some hills of Qarah have an off-white color?

The composition of limestone gives most part of the Qarah hills an off-white color. Because, limestone is a sedimentary rock formed from the skeletons and shells of marine organisms that consists chiefly of calcium carbonate.

This leads us to an interesting fact that the area was under the sea a few million years back.

Though most of the caves in Saudi Arabia are wild and difficult to explore, Jabal Qarah caves have walkways and iron railings a few meters inside for the public to enter safely.
