Lighthouse Beach faces almost due south, fully exposing it to all waves from that direction. It is bordered by Sugarloaf Point and Seal Rocks reef in the north and Treachery Head in the south.
Lighthouse Beach can be accessed either by taking the short walk to Sugarloaf Point Lighthouse or by driving down towards Treachery. This beach can also be accessed by 4WD.
Lighthouse Beach offers good diving, snorkelling, surfing and fishing.
