I would have liked to walk or swim to the island, but we could not find the shallow stretch linking it to the mainland, probably wrong time of the day, although later we met some girls who made it across (swimming). We easily found a boat that takes people to and from the island, at a reasonable price (5 euro adults, 2.5 euro children), and we got about two hours in the middle of the day to spend on the island. The first thing you find is the building that used to be the tonnara. It looks like it had been abandoned a long time ago, but there were still nets in decent condition lying around... puzzling. Past the tonnara there is a path that takes you to the other end of the island. This is lovely, in the middle of dwarf palm trees, dark green against the blue of the sea with splashed of golden sand. At the other end of the island there is a religious statue and a building which is nearly as puzzling as the tonnara: completely locked up, not easy to reach, but with a stair lift to get to the (locked) entrance. The walk is not going to take more than an hour... the rest of the time can be spent on the sandy beach facing Portopalo. This is the place where people can walk to when the tide is low.
