An incredibly fun boat trip with a great captain. A unique kind of boat with a glass bottom so you could see the turtles swimming beautifully. Dog-friendly!

The most complete tour of the southwestern part of the island, with many breaks to swim in the crystal clear waters and discover the coves. The two turtles that we were able to spot from the boat in the bay were also wonderful.

Great experience. Booked on the morning of through this website - didn't confirm as they weren't open until we arrived but we rocked up about an hour before our arrival so we could grab some breakfast. They checked us in as soon as we arrived. Would say if booking the morning of your trip dont expect a shuttle from your hotel - just make your own way there - less stress and loads of parking on the sea front and up the hill in the car parks (all free).

It was an amazing experience, very relaxed, friendly and helpful. The sights were stunning, and everything was very well organised, so easy, picked up by the mini bus and dropped off after.

Super nice boat there is nothing for sale so bring your own food and drinks. Nice sailing no stories but stopping at the right points. Just push through so that we would be picked up from the hotel, they first acted as if they did not know that the transfer was included, had a great day
