Shell Bay is the easternmost end of Studland Beach which stretches from here to Ballard Down. The area is owned by The National Trust, to the west is a nudist beach so don't wander too far that way. This beach is right by the Chain Ferry (so called because it hauls itself along chains which lie on the sea bed) that runs between Sandbanks and Studland and there are facilities near the toll booth and car park.
Fishing here mainly concentrates on bass and flatfish, at low tides you can see evidence of the Training Bank which is a long low bank of rocks that 'train' the tidal flow in and out of the harbour. This is a favoured area for bass.
The stream shown in the photo only appears after rainy periods and drains a lagoon into the sea.
Anglers can often be seen spinning for bass into the main current or bottom fishing ragworm or sandeel baits from the beach.
