Snorkelling the Great Barrier Reef: Playground & Shark Mountain

If you’re visiting the outer Great Barrier Reef from Cairns, one of the most spectacular snorkel stops is the Playground on Norman Reef, alongside Shark Mountain to the west. Our liveaboard trip included three main sites — Norman Fingers, Playground/Shark Mountain, and Wildside Central — and Playground was easily our favourite.

Playground/Shark Mountain – Snorkelling Norman Reef

What It’s Like

The Playground is a maze of coral canyons and bommies, where you can swim through one alleyway after another surrounded by rich marine life. Everywhere we looked there was something new to see, from giant clams to schools of reef fish darting through coral gardens. It felt alive and full of variety.

Directly from the back of the boat and to the east there was plenty to explore in depths of 8–14 metres, while to the west lies Shark Mountain — just one to two metres deep — where divers often gathered.

The Snorkelling Experience

Conditions: Visibility was mostly good, though variable in some areas. Still, it was clear enough to capture great photos and enjoy drifting slowly over the reef.

The reef: Similar to Norman Fingers, this site was a standout. The mix of bommies, shallow reef edges, and deeper coral valleys gave it real variety. What struck us most were the sheer numbers of giant clams scattered across the site.

The Playground also made up for Wildside Central, which has been heavily damaged by cyclones and climate change. Here, the reef felt vibrant and thriving.

Why Snorkel Here

The Playground offers snorkellers a diverse and colourful underwater landscape — coral canyons, shallow reef flats, bommies teeming with life, and the unforgettable sight of dozens of giant clams. It’s easily one of the most rewarding sites on Norman Reef.

Getting There – via liveaboard from Cairns

We visited the Playground as part of a liveaboard trip. After a two-hour transfer from Cairns, the boat moored directly at the site, making it easy to step off the back deck straight into the coral canyons. Snorkelling and diving trips here run daily with several tour operators.

Would We Return to the Playground?

Absolutely. This was our favourite site on Norman Reef, combining clear water, abundant coral life, and a unique underwater landscape. If you only snorkel one spot here, the Playground is the one to choose.
