The best way to appreciate this lake is from the crater rim at Dreamland Garden Restaurant, drink in hand. The view is superb. To get up close and personal with this body of water, scramble down one of the cattle trails and join the children for a swim. But take care: according to local lore, this, the second-deepest lake in Ethiopia, is home to a sleeping devil. From time to time his evil gases kill the fish and send them bobbing to the surface to be scooped up by delighted waterbirds.
