Explore The Dodecanese Rhodes Kastellórizo Hálki Kássos Kárpathos Sými Tílos Níssyros Kos Psérimos Astypálea Kálymnos Léros Pátmos Lipsí Arkí Agathoníssi Share If you’ve come to Níssyros to see the volcano, you’re already there – the whole island is the volcano. Beyond and behind the steep slopes that climb from the shoreline, the entire centre of the island consists of a vast bowl-shaped depression. The hills end in a slender ridge that’s the rim of the caldera, meaning that the two hilltop villages that survive, Emboriós and Nikía, are long thin strips that enjoy stupendous views both out to sea and down into the maw. The interior is etched almost in its entirety with ancient agricultural terraces, mostly long abandoned but giving a very real sense of the much greater population in antiquity. A side road just beyond Emboriós offers the only road access, and continues south to the craters at the far end.
