Beaches in Nisyros are mostly rocky, with black pebbles or sand, which is common near volcanoes. Nothing compares to the sound of black volcanic pebbles rolling down the shore, as the waves retreat. Plus, the sea is crystal clear! Nisyros is still an active volcanic centre along with the centres of Milos, Santorini and Methana.
Gyali, which is 3 nautical miles away from Nisyros and about 16 nautical miles away from Kos, is a small islet boasting some of the area's prettiest waters. The island is mostly known for its massive quantities of pumice deposits. Should you decide to take your boat on to the next islet of Agios Antonios, you’ll feel like heaven on earth. Swimming into the Aegean navy blue waters is once again, highly recommended!
