Cobbler's Bay

Cobblers Bay sits just north of Middle Head in Sydney Harbour National Park, where you can drop anchor and swim straight off the boat into clear, snorkellable water. It's a surprisingly secluded spot given how close it is to the city, with bushland backing the beach and the Georges Head walking trails nearby if you want to stretch your legs. Fair warning: it's a well-known nude beach, so don't be caught off guard.
