Half-Day Great Barrier Reef Snorkelling Tour from Cairns
Ready to explore the world’s most famous reef? Join our half-day snorkel and introductory dive tour from Cairns and discover the magic of the Great Barrier Reef in just one unforgettable morning or afternoon.
First, step aboard our recently refurbished vessel and meet our friendly, expert crew. Then, relax as we cruise for 90 minutes to a spectacular outer reef location. Along the way, we deliver a clear, engaging briefing so you feel confident and excited before you even enter the water.
Tusa Dives half day Reef Trip visits two spectacular dive sites from 21 moorings scattered across the 16 outer reef sites.
Once we arrive, you’ll enjoy up to two full hours snorkelling at a carefully selected outer Great Barrier Reef site. Because conditions change daily, our experienced captain chooses from 17 sites across Saxon and Hastings Reefs. As a result, you always visit the location with the best visibility and calmest conditions.
Whether you’re a first-time snorkeller or already love the ocean, we make it easy. Our in-water guides support you every step of the way. They point out colourful coral gardens, tropical fish, and fascinating marine life so you don’t miss a thing.
Even better, we limit numbers to just 60 guests. Therefore, you enjoy a more personal, relaxed reef experience — without the crowds.
After your snorkelling adventure, stretch out on the sundeck and soak up the tropical views as we cruise back to Cairns. If you’re feeling hungry, simply pre-purchase an optional lunchbox to enjoy onboard. In addition, light snacks are available for purchase during the return journey.
Want to go one step further? Then try an introductory scuba dive and experience the reef from a whole new perspective. Designed for confident swimmers, this beginner dive lets you breathe underwater while a professional instructor supervises you at all times. It’s safe, exciting, and truly unforgettable.
