Green Island and Great Barrier Reef Sailing Tour

4.8 (411 verified reviews)

About This Experience

Ocean Free runs this reef and island day aboard a classic schooner with up to 25 guests. It rates 4.8 from 411 reviews, and it is a slower, more social day than the fast catamaran trips. The operator has two vessels, Ocean Free and Ocean Freedom, and the meeting point depends on the option you book.

You board to coffee or tea, fresh fruit and Danish pastries, then sail out to the reef in about two hours. Guests are welcome to take the helm or help hoist the sails. The skipper moors at a coral garden in a Green Zone of the Great Barrier Reef Marine Park, a site the operator says only its own guests snorkel and dive.

After a snorkel briefing you swim straight off the boat. Wetsuits, Lycra suits and buoyancy vests are provided, and a marine naturalist leads snorkel tours through the day, with in-water help for nervous first-timers. Reef fish, stingrays, turtles and shy black-tip reef sharks are often seen. Diving options include one or two scuba dives, with two divers per instructor for first-timers and a guide for certified divers, at a conservative 10 to 12 metres. Lunch is a large smorgasbord on board with smoked salmon, prawns, meats, chicken and salads, and vegan or vegetarian meals can be pre-ordered.

The tender then runs you to Green Island's beach for up to two hours. Walk across the island, swim, or pay for island extras such as the glass-bottom boat, semi-submarine or Marineland Melanesia. Catch the first tender back if you want another snorkel. On the way home the engines go off when the wind allows, and afternoon tea of fruit, cheese, crackers and cake is served with a glass of wine.

It suits couples, friends and families who want a small group and a sailing day, not the maximum time at the outer reef. You need to be steady enough to move around a moving boat and to use a step ladder in and out of the water. Bring swimwear, a towel, sunscreen, a sun hat and sunglasses; underwater cameras are not provided.

The crew were super helpful and enthusiastic, and couldn’t do enough to help you. The snorkel tour was amazing as you knew what type of fish you were looking at! Overall a fantastic day, would definitely recommend!

This is a great way to put several interest into one day! Sailing, Green Island, snorkeling. The guides are great and helpful and the ship is cool. For us the snorkeling time was to short but for most of the others it was good. All in one it was a great day

A super unique day trip with great crew and small group. A family run company with passion for making the day memorable and fun.
