Along the trail to Napilli Coastline, you would have these beautiful overviews of the ocean. We came to the first beach and there was a sign posted that warned us not to swim in the ocean. There was a wooden sign with all these x's notched on it. About 50 or more x's. Each x was for a person who died in the ocean from the strong currents. Needless to say, we didn't even wade our feet in the water.
