Rottnest Island is fringed by 63 beaches and 20 stunning bays, each with its own distinct views and personality.
And when you walk across the soft, white sand and dip into the water, you’ll discover a whole new world to explore. Rottnest is home to some truly beautiful beaches, and equally magical snorkelling locations, where you can swim among colourful coral, swirling seagrass, and poke around the submerged skeletons of wrecked ships.
These are the top snorkelling spots we recommend you try.
But first, what makes Rottnest Island such a special snorkelling spot?
There are a few reasons that make Rottnest Island stand out for snorkelling.
A big one is the sheer biodiversity in the water. Under the waves, you can find 20 species of coral and come face to face with over 400 species of fish. This is due to the five Marine Sanctuary Zones that surround the island, which have been put in place to protect the pink coral, sea grass, shipwrecks, sea lions, and a range of different fish.
What also contributes to the fantastic snorkelling is the temperature. Rottnest is situated in the Leeuwin Current, which flows down from Indonesia, bringing the warmer equatorial water with it. This means the seas that surround Rottnest Island can be up to four degrees warmer than that of the mainland, creating more inviting conditions.
Our top Rottnest Island snorkelling spots
The Basin
Sprawling out in front of you when you step off the jetty, The Basin is a popular snorkelling spot for a reason.
With a prime location next to the main settlement, it’s sheltered from prevailing winds and currents, creating warmer, calmer conditions. The shallow seabed descends gradually, making it the perfect spot for new and beginner snorkellers, young families, or those just wanting a slow, relaxing start to their Rottnest Island holiday.
Under the wave,s you’ll find large schools of fish darting around, and you might even be lucky enough to see a sea turtle or octopus.
Parker Point
Jutting out on the southern side of Rottnest Island, Parker Point is located in one of the island’s Marine Sanctuary Zones, which was put in place to protect the distinct pink coral that’s found there. Thanks to this, the snorkelling is excellent, with very clear visibility.
As you sink into the waves, you’ll navigate your way through the seagrass beds and onwards to the Parker Point Snorkel Trail. This 800m route takes you out into deeper waters and back again. On the trail, 12 underwater plaques are chained to the bottom of the ocean, each one featuring interesting facts about the sea life that surrounds you.
However, there are some deeper spots here and there, so watch out for drop-offs and underwater currents.
Little Salmon Bay
Little Salmon Bay is just around the headland from Parker Point. Also part of the Marine Sanctuary Zone, it’s sheltered from wind and currents, making it one of the calmer spots on the island.
A favourite beach for regular visitors and travellers alike, Little Salmon Bay features its own snorkelling trail. This 700m loop takes you out into the bay and back, with buoys above the waves and underwater plaques guiding you through the journey. On the plaque, you’ll learn about the unique habitat that surrounds you.
Be aware that with its excellent snorkelling conditions and beautiful coral reef, it can get crowded during the day, so plan your trip accordingly.
Henrietta Rocks
Henrietta Rocks is one of the more exceptional snorkelling spots on Rottnest Island. Clear turquoise water provides stunning visibility, and jutting above the waves, you can see the distinct presence of the historic shipwreck, the Shark.
Almost 100 years old, the Shark broke free from its mooring in Fremantle in 1938, drifting across the channel until it ran aground at Henrietta Rocks. It slowly sank and has lain semi-submerged in the water ever since.
Just 50 metres offshore, it’s enticingly close for those looking for an exciting snorkelling opportunity. When you dive below the waves, you can swim down and poke through the wreckage that’s encrusted in barnacles and surrounded by seagrass, and come face-to-face with inquisitive fish like morwong and bream.
Little Armstrong Bay
Little Armstrong Bay is exactly what the name suggests. Surrounded by large rock formations on both sides, the small beach is sheltered from stronger currents and winds and feels safe, secure, and secluded.
This also creates perfect snorkelling conditions for all abilities. The warm, shallow water just off the beach is ideal for little ones and beginners. As you get further out, an undulating coral reef and deeper water provide opportunities to more experienced divers to explore.
As Little Armstrong Bay is in one of the island’s Marine Sanctuary Zones, this means that no fishing or boating is permitted, and it’s inhabited by some of the island’s more exotic and elusive fish species.
