Volcano islands don't do white sand — they do red cliffs, black pebbles and water like glass.
Red Beach
Rust-colored cliffs over dark sand. Look from the viewpoint, swim if the flags allow.
Perissa & Perivolos
The long black-sand strip: loungers, beach bars, afternoon music.
Vlychada
Wind-carved white cliffs like a moonscape — the sculptural, quieter choice.
Kamari
Organized black-sand beach under the mountain, with a promenade for dinner.
Boat day to the hot springs
Sail the caldera, swim in rusty warm water by the volcano islets.
