Sof Omar Cave
One of the most spectacular and extensive underground caverns in the world , the Sof Omar Cave is found about 557km from Addis. It is a most spectacular and unique sight formed by the Web river, which made a course through the limestone hills and forms relatively long underground water courses with halls and columns of lime stone inside the cave.
The caves currently constitute an important Islamic shrine named after the saintly Sheikh Sof Omar, who is said to have taken refuge here many centuries ago. The large central hall of Sof Omar, the "Chamber of Columns" (so named after the colossal limestone pillars that are its dominant feature) is one of the highlights of the cave system. However, the site has a religious history of thousands of years, which predates the arrival of the Muslims in Bale. Within the caves nature has worked wonders of architecture, where one can see soaring pillars of stone twenty meters (66 feet) high, flying buttresses, fluted archways, and tall airy vaults. Finally, the river itself can be reached, a sunless sea flowing through a deep gorge.
The cave is an enchanting place for adventure tourists, geomorphologies and cave scientist.
