Palea Kameni (Old Burnt Island) is less than 2000 years old, while Nea Kameni (Young Burnt Island) began to form only 425 years ago.

The santorini volcano is one of the favourites attractions of the island. You can see some steam and frozen lava formations. The daily cruises are advertised everywhere so you can not miss the opportunity to visit the Santorini Volcano. Once arrived on the shore of the island of Nea Kameni, you must walk 20 minutes in a 'lunar' landscape to finally see the santorini volcano's crater and and some holes where sulphur steam comes from.
