Like Turin, several times on a hang glider.
Rhossili on the Gower peninsula, Wales
Bodo, Norway
Curium, Cyprus
and Weston Super Mare - On the 20 to 25ft sand dunes. The locals lay in their harness in prone at the bottom of the dune, tip the glider back and as it goes up and backwards over the dune, they pull in the bar to start soaring. Needless to say I didn't try that...
This brief video shows a glider soaring the dunes. The sand at the bottom is the top of the beach.
