The Tawi Ateer Sinkhole was only discovered in 1997 by a few Slovenian explorers. Until this, it was not even known to the locals! It is a natural wonder and is the largest sinkhole in the world. Another natural wonder is the Teeq Cave, which is located atop the sinkhole. It is wise to follow a professional guide if you plan to visit both, as it can be a little dangerous. However, it will satiate your wanderlust as the view is extraordinary and the waterfalls nearby will certainly lure you into paying them a visit.
