Cobourg Peninsula, on the remote western tip of Arnhem Land, is a wild and pristine coastline within Garig Gunak Barlu National Park. The waters here are part of the Northern Territory's largest marine park, featuring fringing coral and rocky reefs, extensive intertidal flats, and sandy beaches. Low tides expose coral reefs and rock pools teeming with marine life. This is one of Australia's most untouched snorkeling destinations, where you can drift over coral gardens in crystal-clear waters surrounded by the raw beauty of a virtually uninhabited landscape. Access is restricted to 4WD (dry season) or by boat, making it a true wilderness adventure.
