All-Inclusive Half-Day Reef Snorkelling Trip from Cairns

4.9 (626 verified reviews)

About This Experience

Pure Snorkelling Adventures runs this snorkel-only half day from D Finger at the Cairns Marlin Marina, and with 626 reviews at 4.9 it is one of the best-rated boat trips leaving Cairns. Among Cairns departures on this site with 100 or more reviews, only a scenic flight rates higher. Numbers are capped at 40 guests, and the operator holds Advanced Ecotourism certification.

The day starts before the boat does. At 10:30am the crew's marine biologists give a free presentation on the reef's species and ecosystems, open to anyone and with no booking needed. Check-in at the pontoon office on D Finger runs from 11:00am and closes at 11:30am, and the boat leaves at 12:00pm sharp. The run out to the reef takes about an hour on a new, purpose-built boat designed for speed.

The site changes daily: the crew choose an outer reef location that suits the weather and sea on the day. You then get about two hours in the water with snorkel guides who swim with the group, show beginners how to settle into it and point out corals, fish and giant clams. Masks, snorkels and fins are supplied, with wetsuits in winter and Lycra suits in summer, plus flotation devices and prescription masks. Seasonal fruit and snacks are handed round, and there are freshwater showers on deck. The ride home is about another hour, and you are back at the marina around 5:00pm.

It suits travellers who want real snorkelling time on the outer reef without giving up a whole day, and people who like to understand what they are looking at. It is not a pontoon day: there is no semi-submarine or observatory, and the operator lists non-swimmers, children under 6 and people prone to seasickness among those it does not suit. For a longer day with lunch, see the <a href='/tours/great-barrier-reef-cruise-by-premium-catamaran-from-cairns/'>premium catamaran cruise</a>.

Despite the all-inclusive name, there is no lunch: eat before you check in, or bring snacks and water. Soft drinks and alcohol are sold at the bar on board. Hotel transfers are not included, so plan your own way to the marina, and leave valuables at your accommodation.

It’s fantastic! The guide and staff were very friendly and knowledgeable about the Great Barrier Reef. They were very attentive to all guests and gave clear safety instructions. They even went to the water with you and showed you what to see. Absolutely brilliant!! Highly recommended!!
