Located in the affluent suburb of Mosman, Obelisk Beach – also called Georges Beach – is a small curve-shaped beach with light brown sand and large nearby sandstone rocks. This beach is part of a national park named Sydney Harbor National Park and it is known to be popular with members of the Gay community. This beach is an official nude beach – if you are planning a clothing-optional visit at Obelisk Nude Beach, please note that there is not much sunlight here in the afternoon, making the temperature here cold if you’re going to be naked.
