The route is well signposted for the beach - continue onto the beach itself. 
Once on the beach, turn left, drive along the sands, close to the beach wall.
If there are tyre tracks to follow, you'll get an idea of where the soft spots are. Otherwise, please be prepared for soft sand now and again.
Do not stray too close to the river. Soft, wet sand quickly transitions to soft, wet and deep mud.  (Don't walk on the mud either!)

The clubhouse is the building you'll find on the beach ahead of you!
