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

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.

The scenery was amazing. We even saw a turtle. The skipper was very experienced and had great control of the boat. Top-notch.
