The cliffs of Santorini suround the sleeping volcano of Nea Kameni (which means New Volcano). It is one of Greeces many National Parks. Each day many boats carrying even more tourists visit this isle, which consist only of Lava rock, and has almost no vegetation. It's about a 30 minute hike to the top of the volcano. In the background we can see the city of Fira, the capital of island of Santorini, on the cliffs high above the sea.
