Snorkelling on Kangaroo Island: Where to Go and What You’ll See

Posted on May 8, 2022

Kangaroo Island’s underwater world is as breathtaking as its landscapes above the surface. Slip on your snorkel and mask, and you’ll discover pristine waters teeming with colourful marine life – from curious seahorses and darting fish to rays, sponges, and even the occasional blue swimmer crab.

There are plenty of great snorkelling spots across the island, each offering a unique glimpse into this thriving coastal ecosystem. Before heading out, check the local weather conditions, chat to a local for up-to-date advice, and always snorkel with a buddy. Let someone know where you’re going and when you plan to return. And of course, respect the marine life — admire from a distance and leave everything just as you found it.

Snorkelling at Stokes Bay Rockpool

Tucked behind the unique rock tunnel entrance at Stokes Bay, this natural rock pool is a hidden gem for snorkellers of all ages. Calm and sheltered from the swell, it’s an ideal spot for beginners or families with kids — but even experienced snorkellers will enjoy exploring the thriving marine life here.

You’ll spot a variety of fish and sea creatures that thrive in the calm waters protected by the surrounding reef. It’s the perfect introduction to Kangaroo Island snorkelling, offering a safe and beautiful environment to enjoy the ocean without heading too far offshore.

Snorkelling at Hog Bay, Penneshaw

Hog Bay in Penneshaw is more than just a beautiful swimming beach — it’s also one of the best spots for snorkelling on Kangaroo Island. Head to the eastern end of the beach, near the historic Frenchmans Rock, and follow the fringing reef just offshore.

This sheltered stretch is home to a vibrant underwater world, including colourful reef fish like the striking Magpie Perch and bold Scalyfin. Calm conditions and easy access make it a great choice for confident beginners and intermediate snorkellers alike.

Snorkelling at Brown Beach

A favourite with locals and visitors alike, Brown Beach (or Browns, as it’s affectionately known) offers an easy-access snorkelling experience with big rewards. Park at the nearby campground and follow the short path to the beach, then swim out from near the BBQ shelter.

Not far from the shore, you’ll reach the reef – a thriving marine zone where you might spot schools of Silver Drummers, curious Banded Sweep, and the distinctive Blackspotted Wrasse. Calm waters and nearby facilities make this an ideal spot for a relaxed snorkel session.

More Top Snorkelling Spots on Kangaroo Island

Red Banks

For those comfortable navigating a steeper descent, Red Banks offers rewarding snorkelling in its sandy shallows and seagrass beds. Keep an eye out for fish darting through the clear water, and for more confident snorkellers, there are reefs further offshore worth exploring. Just take care — the track to the beach can be slippery in parts.

Rolls Point, Kingscote

Right in the heart of Kangaroo Island’s main town, Rolls Point is easily accessed from the Kingscote Yacht Club. Calm and protected, it’s a top choice for families or those wanting a gentler snorkelling experience. You might spot Eagle Rays gliding by or catch glimpses of Zebrafish, Western Talma and little Weed Whiting in the shallows.

King George Beach (Rocky End)

For a more remote adventure, make your way to the rocky end of King George Beach — 4WD recommended, though you can also walk from the end of the access road. This reef system is home to a variety of species, including the quirky Longsnout Boarfish, the brightly coloured Herring Cale, and the banded Old Wife.

Western River Cove

This north coast gem is ideal for spotting colourful reef dwellers such as the Blue Groper, Banded Seaperch, and Horseshoe Leatherjacket. With easy access from the nearby campground and a short stroll over the bridge to the beach, it’s a peaceful cove that’s great for beginners and experienced snorkellers alike.

Harveys Return

Tucked away on the island’s western tip, Harveys Return is a remote spot for those seeking a challenge. The 750-metre hike in is steep but short — and absolutely worth it for the chance to see rare marine species like Harlequin Fish, Rainbow Cale, and Blue Gropers in the wild. Only recommended for experienced snorkellers.

Hanson Bay

Sheltered on the south coast, Hanson Bay is a haven for curious snorkellers. Explore its calm waters to find invertebrates and reef fish like the Eight-armed Seastar, Sea Sweep, and Bluethroat Wrasse. Stick to the first beach, which is generally safer for snorkelling, and always check local conditions for rips or currents before swimming.

Vivonne Bay

Often hailed as one of Australia’s best beaches, Vivonne Bay also offers excellent snorkelling around the jetty and towards Point Ellen. This is the safest area for snorkelling, as other parts can be affected by swell and rips. With the right conditions, keep an eye out for Southern Goatfish, Smooth Stingrays, and Dusky Morwong drifting through the clear water.
