The fantastic limestone caves of Sof Omar are a must to be visited.
The road leaves Robe town, crossing the farming areas to the east, before descending into the lowlands. Here the vegetation is very different being dry lowland with wooded grasslands. The caves lie at 1,300 m above sea level.
Very different animals occur along the way as well, most noticeably the Greater and Lesser Kudu - both relatives of the Mountain Nyala, and the tiny dik dik antelope.
The caves themselves carry the whole flow of the Web River that rises in the Bale Mountains, underground through wonderfully carved caverns for a distance of one and a half kilometer. There are over fifteen kilometers of associated passages, which require skill, time and special equipment for a full exploration.
However, a friendly local guide will show you enough to take your breath away and make the trip worthwhile, for an hour or for as long as you care to spend.
A cool dip in the clear River afterwards refreshes you for the return drive.
