The price was reasonable at €10.00 per person. Since the island was incredibly busy, we opted for a short visit. A text message was enough to get picked up again 10 minutes later. Other boats have a more extensive program with sightseeing stops and swimming stops. If you want more freedom, the boat taxi is a great option.

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.

This experience was awesome, the staff very kind. We rented a boat without any license and had fun while zooming through the waves.
