In reply to maybe_si:
I can second Fall Bay/Lewes Castle, lovely crag. Lots of great routes, Osiris (VS 4c), Isis (HVS), Seth (E1), Lazy Sunday Afternoon (E2). Yellow Wall is also great (not climbed there personally, but lots of people recommend it) and there are plenty of hard routes to go at. If you want some easier stuff Three Cliffs and Pobbles have some nice easy slabby routes. Lots of soloing and bouldering to be done there.
