Just north of Perth, Marmion Marine Park is a snorkelling and diving playground of limestone reefs, ledges, caves, swim-throughs and crystal-clear lagoons. It’s also a top spot for whale watching (in season).
The marine park stretches north from Trigg Island, a 20-minute drive from the centre of Perth and a short boat ride from the launch sites at Hillarys Boat Harbour and Ocean Reef. There’s even a novice-friendly snorkel spot you can access off the beach at Mettams Pool.
Seabirds, dolphins, sea lions, rays and a huge diversity of other marine species call this coast home. Migrating humpback whales can also be spotted between the months of September and December. Hop on a whale watching tour at Hillarys Boat Harbour to get a closer look at these majestic visitors.
Private dive charters will take you out to explore Boyinaboat Reef, North Lump, Whitfords Rock, Wreck Rock, Wanneroo Reef, Cow Rocks and the wreck of the Centaur.
Throw in a line from the designated shore fishing spots and you could hook some herring, skippy and tailor. Or join a fishing charter and head out beyond the sanctuary zones to chase a bigger catch.
