Kimmeridge Bay is ideal for snorkelling as its wide and shallow; up to about seven metres. There is a snorkelling trail put in place by the Dorset Wildlife Trust with buoys marking five different habitats with different marine life. Black shale reefs run out from shore, covered in barnacles, weed and fish. To the west, the seabed turns to gravel with rock strata which is good for spotting crabs and scallops. The ledges to the east of the bay are very shallow. The bay has a lot of interesting marine life and seaweed of every colour imaginable. A great spot, almost tourist free and very peaceful.
