Warrain Beach is the surfing beach for the settlement of Culburra. It begins on the south side of Penguin Head and runs to the south for 3.7 kilometres past the usually blocked mouth of Wollumboola Lake to the low rocks at Kinghorn Point. Culburra Surf Beach is great for swimming, surfing and scuba diving.
Car parking is provided at the surf club and by the north side of the lagoon entrance, while in the south a track leads off the Currarong road to the back of Kinghorn Point.
Due to the beach being recognised as a popular surfing destination it is not recommended to take children under the age of seven or children who can't swim. The beach is patrolled during summer.
