📍 Bale, Oromia
One of the largest cave systems in Africa, carved through limestone by the Weyib River.
The Sof Umar caves lie about 110 kilometres from Robe town. This cave system is one of the largest in Africa. The Weyib River cuts through a deep gorge and into the rock formation, creating a mass of chambers and tunnels that visitors can explore.
The smoothly worn limestone forms majestic gates as the river enters the cathedral-like caverns underground. The tunnels and passages worn by the river stretch like an underground spider's web for about 15 kilometres, though the main walking route from the entrance to where it emerges from the rock is only just over a kilometre, and takes guests about two hours to walk.
The caves are a reputed Islamic heritage site, dedicated to the Sufi Sheikh Safiy Ullal Umar - abbreviated as Sof Umar. The Sheikh is said to have been both the nephew and the disciple of Sheikh Hussein. He lived and worshipped in the cave and taught Islam to his followers many centuries ago, and to this day pilgrims come twice a year to offer prayers and sacrifices.
Entry permits for the cave system are arranged, and a professional subterranean caving guide with a high-powered torch leads the route, with a local cave scout for safety.
You walk the full 1.2km main chamber through-route, from the river gate at the entrance to where the passage emerges from the rock - roughly two hours underground, past the fluted limestone pillars and the cathedral hall.
The Islamic heritage of Sheikh Sof Umar and the pilgrimage practices still observed at the site are narrated as you go.
Not included: specialist caving headlamps and waterproof footwear, commercial cave photography fees, and tips for the cave guides and scouts.
