What to Expect

Check-in is at 8.40am at A Finger, Cairns Marina, with departure at 9.00am. The vessel travels up to 90 minutes offshore to reach the Outer Great Barrier Reef, where conditions are typically clearer and marine life more abundant.

During the cruise, the crew provides a comprehensive safety briefing and outlines the day’s snorkelling adventures. Marine guides explain reef etiquette, snorkelling techniques and the types of coral and marine species commonly found at the selected sites.

Upon arrival, enjoy up to two hours of guided snorkelling at reef locations chosen on the day for optimal visibility and sea conditions. The captain selects sites based on real-time weather to ensure the best possible experience.

This Cairns Outer Reef snorkel tour is suitable for beginners and experienced snorkellers alike. In-water guides assist with equipment, provide reassurance for first-timers and identify marine life including reef fish, giant clams, hard and soft corals, and seasonal sightings such as turtles or reef sharks.

From June to August be on the lookout for Whales as they migrate through the northern section of the Great Barrier Reef.

After your snorkelling session, make use of the onboard fresh hot showers before relaxing on deck for the return journey to Cairns. Guests who have pre-purchased a lunch box can enjoy their picnic on the main deck or in the open-air seating areas while cruising back along the Coral Sea coastline.

The tour returns to Cairns Marina at approximately 2.00pm, making it one of the most efficient half-day Outer Great Barrier Reef snorkelling tours available from Cairns.
