Serious surfers should grab a few mates and charter a boat to the Muiron Islands, just off Point Murat, where there are countless breaks and no one to ride them. You can camp on South Muiron with a permit from Exmouth DPaW. There's also excellent snorkelling and diving – this is the most northerly point of the Ningaloo World Heritage area.
Your charter fee should include all meals, accommodation (onboard or camping) and fishing and snorkelling gear. Charters can be arranged through the Exmouth visitor centre.
