Bimah sinkhole is beautiful natural landmark - a place of refreshment at the long coastal road of Oman.

Bimah sinkhole was formed in limestone by a collapse of large cave chamber. Earlier locals believed that this hole was formed by meteorite ("piece of Moon").

The sinkhole is approximately 50 by 70 m large, 20 - 30 m deep. At the bottom is located deep blue-green lake with a heap of rock - remnants of the collapse.

Municipality has developed a park around the sinkhole, there is built concrete stairway leading to the lake. Locals and tourists often enjoy a refreshing bath in the lake.

Most likely the sinkhole is connected to the 600 m distant sea. Top layer in the lake is crystal clear, but at the depth of some 8 m water has sulphuric taste due to sulphur oxidizing bacteria and is less clear.
