Not in the same league as some of the places mentioned above, but Weybourne (next along from Cromer) is a fun outing for confident newish PPLs. Small knoll in undershoot mucks up your visual perspective, sea cliff at far end concentrates mind, ski jump departure over cliff great fun.
Hmmmm, Glacier du Tour: skied it, never flown it. This September I'm going to get checked out for Courchevel (tree lined rocky ridge in the undershoot, no go-arounds, land up a ramp, lauch off a precipice: http://www.aeroclub-courchevel.com/), and might ask the instructor to pop over for a look at the Glacier, while we're at it.
