MikeJ is correct. If you want to walk, and it is a very pleasant walk, out the main "gates" at Bembridge, and through the caravan park you fly over on the westerly approach. The walk is along the beach and you cant get around at high tide. You use to be able to follow the cliff top coastal path but that is now in the sea(!) and I dont think has be repaired. There is only a very short section which is tidal and you can scramble around at any state - but it is a scramble.
Taxi is about 5 minutes. The very nice people at Bembridge will even telephone for one in advance if you ask them on the radio in bound.
In any crosswind above 15 knots the approach is a little more interesting than most over the cliffs and caravan park.
