Carrick Roads (10 – 30 metres)
Carrick Roads can be dived on the eastern or western side. It is generally shallow, however 35m can be found in certain areas. It is very similar to the Helford, muddy in the estuaries and a mixture of shale and sand elsewhere. Large volumes of fresh water enter the sea from the River Fal and the Helford River in winter. There is an abundance of life on the river bed with lots of scallops and shellfish. Carrick Roads ranges in depths from 10–30 metres.
