This was a special add-on activity during a multiday tour of Mycenae, Nafplio town, Epidaurus plus Hydra & Spetses islands. Swimming and snorkeling is the ideal way to relax and enjoy the swimming pool like coastline of Peloponnese. You can spend hours swimming, if at the same time, you are snorkeling. Just start by examining the underwater world and you will soon begin to collect some very interesting sea shells & sea urchins. Sea urchin eggs is alive chaviar … sweet & salty!
