Three Islands Group National Park is a remote cluster of eight islands (Three Islands, Two Islands, and Rocky Islets) lying 44 km off Cooktown in Far North Queensland, within the Great Barrier Reef Marine Park. These protected continental islands are surrounded by vibrant fringing coral reefs and crystal-clear turquoise waters, offering exceptional snorkeling and diving among pristine coral gardens teeming with reef fish, turtles, and rays. The islands are also critical seabird nesting sites, adding to their wild, untouched appeal. Snorkelers can explore shallow reef flats and drop-offs around Three Islands Reef. Access is restricted to protect nesting birds — Rocky Islets are off-limits, and camping on Two Islands is only permitted April–August. This is a true off-the-beaten-path destination for experienced snorkelers seeking solitude.
