One of my favourites in the area is Chapmans Pool. There’s a car park for St. Aldhems/Albans Head at the western end of Langton Matravers and a choice of easy or precipitous routes down. It’s very close to Swanage and the tide times are the same.
The bay itself produces Bass, particularly where the freshwater runs into it. But there’s a lot of rock marks from the headland itself, through Chapmans Pool and a little further west before the sea meets the cliffs that produce Bass, pollack, wrasse etc.
It’s worth a walk anyway, I nearly always see Peregrine Falcons and picked up a couple of glow worms one summer night walking back to the car park after a session. My kids’ minds blown.
An investigation at low tide will pay dividends and show the deeper water.
Might I also suggest investing in Sea fishing in Dorset, by Ken Stoker. If you can find a copy. Loads of marks that are still relevant 50 years after he wrote it.
Tight lines.
