Once you get to the Ocean Beach car park walk onto the beach and head north up the beach for about 1km (or about 15 mins walk) until you reach a sand dune area backed with a few trees. This is where most nudists gather, particularly gay men. Be extra careful if going for a swim as it is not under patrol and there can be rips so dont go out too deep. There is not alot of shade so bring a hat, sunscreen and an umbrella if you like more shade.
