To participate in the activity of snorkelling, you must be confident in the water with the capacity to swim unassisted. If you are a poor swimmer, you may not be suitable to snorkel in the open water. Not all passengers will be suitable to snorkel, and our experienced crew have the discretion to advise against snorkelling if deemed “not suitable for the activity”. This is for the safety of the passenger. Please be advised snorkelling can be a strenuous physical activity, even in calm water and that older people are at an increased risk of death and/or injury due to a higher incidence of medical conditions made worse by physical exertion, such as heart disease and stroke. All passengers intending to snorkel will be asked to complete our Medical Declaration for Snorkelling form. Our experienced crew will discuss any issues relating to medical conditions and swimming ability. Sailaway reserves the right to decline any passenger from participating in snorkelling if we are concerned about your health condition and/or swimming ability. This is for your own safety, please listen to the advice of our experienced snorkel guides to ensure the safety of our guests.
Our Sailaway vessels are luxury sailing catamarans and we offer a pure sailing experience. This means the vessels travel in open seas and will move around whilst under sail. The decks of the vessels are multi levels and can be slippery when wet. Passengers must have good mobility to safely move around the vessels, step onto the glass bottom boats (if applicable) and get in and out of the water via the ladders on the back of the vessels. Unfortunately, we do not offer wheelchair access due to the layout of the decks and saloon areas. Our tours are adventure experiences for active travellers. Please choose your tour carefully to ensure it is suitable for your experience, age and physical health.
For a full refund, cancel at least 24 hours before the scheduled departure time.

Great boat and crew. Very professional without being stuffy. Snorkeling was terrific. Good food. Light lunch (or more if you wanted it)

Staff was nice and super helpful. Catamaran was the Sailaway VII. We had pretty choppy seas on the way there and back, which is 2 - 2.5 hours each way. A few folks were seasick. The snorkel sites were good, we saw beautiful corals and some deeply colorful blue ones. We saw fishes and a turtle. They gad a glass bottomed boat anchored and this was also a fun experience taking those who-opted to sit out a snorkel a little further out to see corals & fish. Staff was very attentive during the snorkels. Lunch buffet served and snacks for breakfast after lunch. Lunch buffet was yummy. Glad we went, wish weather would gave cooperated.

Truly exceptional experience with Sailaway. Great staff, Captain, and vessel. Knowledgeable staff provided a presentation on the reef on the way out and snorkeling guidance as well. We saw hundreds of fish, and also sting rays and the elusive sea turtles.

An excellent day from start to finish! Very well organised with helpful support from the reservations team when booking and to the boat crew on the day. The crew were superb. The itinerary was well presented and their advice and support on the day was exemplary. Their knowledge of the Reef was fascinating. Great value for money. We'll be back!

The tour operators were very accommodating to both the experienced and novice swimmers. They were very vigilant in making sure all snorkelers were safe, although we had mild waves. The breakfast, lunch and afternoon snacks were delicious. The snorkeling areas on the reef were beautiful with plenty of fish and coral life. The onboard presentation by the marine biologist was very informative before we went into the ocean. All in all it was a highlight of our trip to Australia.

Amazing day on the reef. This is a MUST tour if you want to experience the Great Barrier Reef. The day with Sailaway was top tier and highly recommended. The crew was very professional and helped us have a most excellent day.

lt was my first time snorkelling and at the age of 60 i was very anxious about whether the trip was for me The main thing to say is that the staff on the boat are incredibly helpful patient and supportive and a special shout out to Erin who took me under her wing and made me feel safe and gave me the confidence and belief in myself that I could do it She took me out to the reef with her using her buoyancy aid and showed me how the most amazing corals and fish,pointing out giant clams, corals, rays and fish Without her I could have missed out on what truly was one of the most spectacular experiences of my life !
