The isolated part of Heet with Mount Al Jubayl in the background.

You get an exit to 'Heet' which is about 40km from Riyadh City Center (in the Al Kharj highway) going towards Al Kharj.

About 5km from Heet Exit towards east on an off road takes you to this entrance of the cave with coordinates:

N: 24 29'09.6
E:046 59'48.2.

The wide entrance of the cave gets bigger and bigger as you go close to it. For a good start, the team of eight had to stuff its stomach with breakfast.

Face of Ain Heet Cave.

The mouth of Ain Heet cave is about 20 meters wide and it narrows down to approximately 5 meters while you cave a distance of 100 meters inside.

Like most cave systems, Ain Heet cave too is formed in the limestone by dissolving the anhydrite minerals inside. It was said to be the area where the oil explorers found the first surface outcrop  of anhydrite minerals in Saudi Arabia.

Most part of the entrance seems fragile and freshly downed limestone pieces were found at the entrance.
