You will be amazed by how long this cave is. It is a staggering 15.1-kilometer long cave and it is the longest cave in all of Ethiopia. This cave is near the Bale Mountains and it also has the Weib River flowing in it. Easily, this is one of the longest systems of tunnels in the entire African continent. It was mostly used in the early worships of Muslims, as well. Some of the pillars they have made even reached a sky-piercing 66 feet high. The best thing to see here is the Chamber of Columns.
