This place has it all. Salfuric pillars coming out of the ground, steam pipping up from several places, amazing scenery, a decent place to enjoy a cooling drink afterwards.

Nisyros is one of several Greek islands that are volcanic. This visit into the crater of an active volcano is a rare experience and should not be missed in any visit to the island. The hydrogen sulphide smell is oppressive at times.

We took a coach trip here. There's a small shop and toilets and a place to sit in the shade. For a few euros you get to walk down to the crater itself which is well worth it. It's not for anyone unsteady on their...More
