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).

Luca · CoupleITItaly

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.

Ashima · FamilyGBUnited Kingdom

We had a great day out. Part of our family scuba dived as the rest snorkelled, it was great to be able to do two activities and stay together on the same boat. We booked through Checkyeti and the company Eurodivers were amazing, great communication, attentive and helped us have a fabulous experience. We prebooked sandwiches which was a good choice as after the first dive/ snorkel we were ready for some food. And a warning the timing they set sail is always mornings so if you see an afternoon option I would double check with Eurodivers before setting off. We had a great day and would not hesitate to recommend them.
