We went on a boat tour around the island. The blue grotto was not accessible as the tide was too high and the sea was too turbulent to get in. The entrance is very small. That did not spoil our enjoyment as the ride around the island was beautiful and there are so many caves all along the coast.
We had a lovely last lunch in Grande Marina, eating a whole fish that had just been caught. We left for Salerno, heading out to sea away from all the boat traffic. We saw more tuna and they vanished before we could get too close.
