Babbacombe Beach is well known as a diving site both for locals and visitors and is used as a training area aswell. The shoreline provides a gently sloping sea bed which is however very rocky. Most of these are small (few pounds each). Depths reach a maximum of around 15m depending on the tide which can be quite variable (1.5m on Neap tides to approximately 4.5m on Springs).
The good news is that there are no real currents close to the shore but increase to currents up to 1 knot more than 500m...
