Maletsunyane Abseil, Semonkong, Lesotho
The Maletsunyane Abseil is the longest commercially run abseiling location in the world. It stands at roughly 670 feet tall and runs parallel to the Maletsunyane Falls. Be prepared to get wet. Depending on the weather you might have trouble seeing through the fog, so pay attention to your surroundings and tread carefully. The water from the Falls also makes the rock slippery, so wear appropriate shoes, peeps.
