Glass Bottom Boat Tour 
Description
Several companies offer 1 or 3 hours cruises from the old harbour out to Lazareta islands. When the boat reaches the island it ties up in the bay and then you can either go swimming/snorkelling or use the glass viewing panel in the bottom of the boat to see the fish and turtles swimming in the sea below.
