A Wildlife Experience Like No Other

Snorkelling on Magnetic Island offers a peek into new realms of rainbow-coloured fish, serene rays and wise old turtles.

Ocean-lovers, grab your fins; with the weather settling and stinger season subsiding, it’s time to plan your next snorkel trip. With golden sandy bays, koalas peeking from the gum trees, and a charming laid-back buzz, Magnetic Island is a top choice, where visitors spend days paddling between island paradise and underwater oasis. With a variety of snorkel trails to choose from, here’s a guide to help you plan your journey.

Start off at Geoffrey Bay, where a snorkel trail begins about 400 m from the beach, on Marine Parade. Look for the four numbered surface floats that mark the trail.

From the shore to the first float, you will swim over a green grassy refuge of sargassum and funnel weed before the next leg takes you over coral reef builders, including fascinating brain coral, spiky staghorn and fluffy cauliflower coral.

Next, you will see unique lettuce corals, omnivorous beings that eat both plants and tiny animals. Here, the corals are dotted with familiar tropical fish, like angelfish, butterflyfish, and yellowtail demoiselles.

Heading towards the first float, you will discover an abundance of sargassum and funnel weed as a refuge for various species. The journey to the second float will take you over vital coral reef builders, including staghorn, cauliflower, and brain coral. Towards the third marker, you'll swim over Lettuce corals, unique omnivorous corals that gorge on plants and tiny animals, as well as Angelfish, Butterflyfish, and Yellowtail Demoiselle fish.

This area is also home to five of the island's 30-year-old giant clams, cultivated by world expert Dr Rick Braley. In 2026, they turn 40 years old, weighing around 100 kg each, with shell spans of up to 1.3 metres.

Heading past the fourth marker, on a clear day, you'll find the Moltke wreck, a three-masted German barque that was wrecked in 1890 and found its final resting place by 1911. The impact has created a unique underwater refuge for marine animals.

Stronger swimmers can find a WWII aeroplane propeller and engine block a short swim from the trail. These remains belong to a CW-22B Curtiss Falcon, serial number 3771, which crashed on December 5th, 1943, due to reported engine failure. Following the high coral cover, you will be led back to surface float one.

Next, Alma Bay is a gem for those who like lazing on beautiful golden sands between leisurely dips. Patrolled by lifeguards and restricted to boats, it’s a great choice for families and beginners.

Snorkellers should float towards the right headlands, where coral gardens teem with colourful, tropical reef fish, elegant rays and adorable turtles.

Florence Bay is a top spot for shark lovers, with blacktip reef sharks often in the area. Leaving the shady shoreline and taking an easy path into the water, you will soon gaze over the area locals dub ‘mermaid’s cove’, a treasure trove of coral and tropical fish that is described as an immersive and magical experience.

Arthur Bay is another picturesque cove, offering calm waters and the chance to explore the fascinating Octopus wreck. Thought to be a bucket dredge dating back to 1928, the wreck lies in 8–10 metres of water and is home to a much-loved local resident, Shelly the turtle, who is often seen gliding through the bay.

Snorkel cards sold at many Magnetic Island retailers offer easy maps of the island’s major snorkel trails. A $5 donation per card supports trail maintenance, and recycling drop boxes are available once you’re done – proof that you’ve chosen a destination that really cares about the marine life that brings tourists to its shores.
