West of Lake Langano lie the twin lakes of Abiata and Shala, which form part of the national park. Identical twins these lakes are not: Shala’s 410-sq-km surface sits within a collapsed volcanic caldera, and depths exceed 260m in some areas, making it the deepest lake in Ethiopia, while Abiata’s highly alkaline waters rest in a shallow pan no more than 14m in depth.
