The Marmion Dive Trail is the latest addition to Perth diving and snorkeling sites. This is the newest dive and snorkel trail located offshore from the city’s northern beaches, and encourages water lovers to explore the submerged world of the popular Marmion Marine Park.

The state already has several underwater trails, including off Rottnest Island, the Omeo Shipwreck Trail and the Abrolhos Islands, but this new dive, officially named the Marmion Angling and Aquatic Club dive and snorkel trail, is the most accessible and was a decade in the making.

Snorkellers and divers can follow 20 submerged concrete plinths along a 400 metre path, guiding them through the underwater world of the popular marine park, located offshore between Trigg Island and Burns Beach, in Perth’s north. The plinths are printed with facts about the sea creatures and features of the lagoons, reefs and small islands of the marine park.

How to find the trail

Located offshore from the Marmion Angling and Aquatic Club, on West Coast Drive, in the Marmion Marine Park, the trail is approximately 400 metres long and varies in depth from 2 to 6 metres. You will see the start of the trail marked with a surface float. Arrows on top of each plinth indicate the direction and distance (in metres) to the next plinth. You do not need to visit all of them to have an enjoyable experience, simply come back another day and continue the journey.

The trail starts at the shore and goes out about 100 metres in a protected lagoon and to the outer reef, for a maximum depth of six metres. Keep an eye out for Port Jackson sharks, wobbegongs and rays, as well as schools of WA fish species including tailor, tommy ruffs and King George whiting, colourful nudibranchs and anemones. Other visitors include seals and rare Australian sea lions from their island colonies dotted around the marine park and, during the winter months, humpback whales.

Facilities Nearby

There are many facilities and services close by, some within walking distance and others a very short drive away, including:

  • Marmion IGA – the shopping centre offers toilets and plenty of options for shops
  • Toilets & Changing Facilities are located to the north of the site at the Sorento surf club

*The closest public toilets that also provide a Changing Place, baby change table and outdoor shower can be accessed from Maraboo Loop, near the Ngarkal Beach Water Park (view Google Map). Toilets are also available at the Port Coogee Shopping Centre on Marine Parade.

Keep in mind

Always stay on the safe side of your abilities. Most of the trail is around 2.5-5m deep, designed for snorkelers and novice divers. As always with water-based activities, swim within your limits, and take a buddy. Always swim and dive with a buddy.

Be sure to check the MAAC surf cam:

As Always check the weather before you go. If there has been a lot of swell around the water can be very murky. Marmion beach is not protected, so there’s not much point in snorkelling when the water is all stirred up and visibility is only a couple of feet.

The club is already working on the next section, which they hope to open in about 12 months. The dive trail is free and accessible to snorkellers and divers of all abilities, including children. See
