Not a high ridge, but easily soarable and plenty of room for practicing wing overs, and generally playing around. The ride is at least 500m long, so >10 PG could play together without any problems.

The main bridge to Quinana beach will ensure you arrive right on the beach. From there, the ridge is visible a few hundred meters to the east. Driving on the beach is permitted, so it is possible to drive all the way to a launch site.
