At the base of the cliffs rising to the town of Oia, the port of Ammoudi Bay glistens above sparkling turquoise waters. 

Descend the 200 or so steps down from Oia, and you are in the picture-perfect setting that is Ammoudi, known for quaint Greek tavernas serving the catch of the day just inches from the waves, and isolated coves ideal for swimming. Another popular activity is cliff diving if that's what gets your adrenaline pumping.

For a less adventurous and still exhilarating experience, hire a sailboat to bring you to the volcano for a swim in the hot springs
