  • Cairns: Snorkel & Dive a Secluded Great Barrier Reef Island

    7. Cairns: Snorkel & Dive a Secluded Great Barrier Reef Island

    Take a tropical island adventure and enjoy a leisurely 30-minute cruise down the colourful Mulgrave River. Soak up the beauty of the surrounding rainforest-clad hills from the cabin or shaded deck and admire the panoramic views. Don’t forget to keep your eyes peeled for crocodiles along the mangrove’s edge! After a short open water crossing, arrive at Frankland Islands National Park, your tropical destination for the day. A secluded and ancient marine environment, the Frankland Islands are home to thousands of plants and animals species, all waiting to be discovered.

Snorkel straight from the pristine white sandy beach, where an expert marine naturalist guides you over colourful corals and tropical fish while explaining this unique and wonderful ecosystem. ...

    Great, engaging and fun crew. Beautiful lunch. Snorkel safari is wonderful. The 9 hours duration indicated is not true. You leave the island at 2pm. Also the beach activities are not really available after lunch, so it’s either snorkel safari or beach activities not really time for both.

  • Cairns: Green Island & Reef Full-Day Sailing Cruise

    We loved being spoilt by the crew! Only 25 people on the sailboat made it very enjoyable! The lunch was excellent! Snorkeling from the private mooring was superb! I highly recommend this sailing experience to any who travel to Cairns!

    This trip was amazing! We snorkelled at 4 different locations at Norman's reef (it seems small on the map but it offers such a variety of reef landscape) for our 2-days at the reef and saw all kinds of fish and corals, even small sharks and turtles! A few tips: If you want to maximize your stay in the water book an overnight stay because this way you get 7 dives while a 1-day trip allows for just 2 dives. If you get seasick bring some pills as even on the big boat for the night you can feel the waves a bit. The sharks that you might see are small and not dangerous at all so don't worry. The team of Divers Den was amazing, very attentive and fun! Thank you for the great time! :)

It was the most amazing trip. To do all 3 in one day was simply the best day. GSL was the airline we booked with for the Reef flight and they organised this for us perfectly.

Easy to book, enjoyable experience and very helpful and friendly staff. Amazing scenery. Bus pick up and drop off made for a smooth, enjoyable day.

Would advise anyone to take this trip. Skyrail up and train back after spending 3 hours in Kuranda. I could have done with an extra hour

The staff were so friendly and knowledgeable. The flight was awesome. The rest of the day was also full of beauty and inspiration.

Great experience. Excellent communication and all staff were lovely.
