“The guide was very nice and he knew a lot about the underwater world. Unfortunately we snorkeled just an hour, i would have liked it more, to snorkel further after a little break than just swimming and checking out the beach. But i have to admit, the spot we were at was veery beautiful, the water was clear, the beach is in a nature reserve and there were almost no people. Like a secret escape from busy athens.

Kayaking as a team of two, we all learned more about keeping in synch and working better together, especially when threading the needle to squeeze into the sea cave. :) We were glad to rest on the island and share a light and delicious lunch, where we also looked at the rocks and pebbles on the beach, as well as snorkeled.…”
