Fodor's Expert Review Agios Nikolaos Island

Not a beach per se, but one of the best swimming spots on the island. From Ia, walk down to Ammoudi, then follow the path past the Sunset taverna to the narrow channel that separates Santorini from little Agios Nikolaos island, so named because of the small chapel that rests on it. Intrepid adventurers swim across and rest on ledges beneath the chapel, enjoying sensational views of the cliffs and Ia perched high above. Amenities: none. Best For: swimming.
