Embellished with stalactites and stalagmites, this is the only cave in Oman developed for tourism. Unfortunately, it floods frequently putting it out of action for months at a time. It was closed at the time of writing. If the promise of reopening is kept, a visit to the interactive on-site geological museum is worthwhile as it explores some of the features that have made Oman internationally renowned among geologists.
If the cave is closed, head for a shady natural park with flowing water on the road towards Tanuf, 2km from the cave. It makes a pleasant place for a picnic.
