White lanes, a Knights' castle and volcanic-island life by the harbour.
Mandraki is Nisyros's main village, with the monastery of Panagia Spiliani, a volcanic museum and a shaded square paved in dark stone.
Mandraki spreads below a Knights' castle and the cliff-set monastery of Panagia Spiliani. Its lanes use black volcanic stone in patterned floors, and the central Ilikiomeni square is shaded by large trees.
The Archaeological Museum and nearby Paleokastro reveal the island's ancient history, while the Volcanological Museum at Nikia explains the active caldera inland. Mandraki is the natural base for balancing crater visits with harbour evenings.
Practical information
Ferries and excursion boats arrive near the village. Buses and taxis serve the caldera; visit craters early, obey gas and heat warnings and wear closed shoes.
