Harrat Kishb is one of Arabia's 12 large lava fields covering 85,000 sq
kms.

Salt lake in two-km-wide Wahbah Crater.

Crossing a harrat is no easy task, as you can rarely go in a straight line.

|
We camped at a lonely spot near a mountain called Jebel Hil.

Seven meters below the surface, two long passages can be entered.

Tall stalagmites of dove guano look spooky in the murky light.
