With a number of sheltered and protected bays, and breathtaking sights just metres from the shore, Wadjemup offers snorkelling and diving adventures for a range of ages and abilities. 

Take your pick from the popular snorkelling spots of The Basin , Parakeet Bay and the shipwreck at Henrietta Rocks , or simply cycle from beach to bay to find a new favourite.

For a story-filled swim, explore the snorkel trail at Little Salmon Bay or Parker Point and be guided by the series of information panels attached to the seabed below.

Thanks to its diversity of marine life, clear water, reef caves and swim-throughs, Wadjemup is a spectacular diving destination. Although there are countless reef dive spots, Crystal Palace is one on the south east side that showcases the island’s intricate network of underwater caves, with an expanse of flowing submarine flora visible from the surface and dark blue openings in the reef teasing at hidden pathways below.

The waters around Rottnest Island also disguise the sunken remains of multiple historic ships dotted around the bays. Many of these are impressive dive sites, with Macedon and Denton Holme lying close enough for one dive visit. 

Macedon still sits upright, the ribs and gunwales of the hull splayed open, merging with reef, while Denton Holme’s bow stretches upward, almost breaching the surface.
