"AlHoota Cave" lies in the southern part of Al Jabal Al Akhdar (Green Mountain), specifically near Wilayat Al Hamra in Ad A'Dakhiliyah Governorate. It is about two hours drive away from Muscat and half an hour from Nizwa. AlHoota Cave was discovered by local residents hundreds of years ago, and its name derives from the village where it is located.
The cave extends for 5 kilometres underground, but it may only be accessed for a distance of 860 metres, ending at Cave Lake. Perhaps the visitor to this cave, passing through the surrounding area on his way there, will find proof of the claim that "caves are the underground equivalent of the landscapes we see above ground, like valleys, streams and springs." This cave has two holes through which water cascading from the mountain top enters via the (ALHoota) hole, and exits through the other (AlFalaah) hole after passing through the connected cave passageways.
AlHoota Cave Lake:
AlHoota Cave Lake is located at the end of a footpath. It is 20 metres deep, but there are many parts whose depth surpasses that. It is rumoured that it extends up to Tanuf Valley in wilayat Nizwa. The lake contains several species of blind fish: some are without eyes but have long bristles to sense their food, while others have very small eyes. Also living in the lake is a rare type of blind fish, coloured a translucent pink so that you can see the skeleton of these small fish.
