Nisyros an intimate and photogenic island in Dodecanese group of islands in Aegean Sea, is eclipsed by nearby Kos. Nisyros population is considered to be after the most recent census about 1000.The geographic coordinates of the island are 36°35’28.2″N 27°10’00.0″E.

Nisyros is the island of the volcano and relaxation. It’s most famous for the otherworldly ‘Stefanos’ caldera, the volcano crater, which gives rise to the island’s fertility; drawing botanists and gardeners from around the world to see its unique flora.
Nisyros is like an abandoned island in Greece. Nisyros’ main town and port is Mandraki. Mandraki is a languid maze of whitewashed alleys radiating from the aquamarine harbour, vividly strung with drying octopus. The black and volcanic beaches are nothing spectacular; this is more a place for exploring dazzling hilltop villages like Nikea and Emborios, hiking a little and sampling the local produce.
Above Mandraki, Paleokastro or else the Old Kastro, the impressive Mycenaean-era acropolis, has restored 4th-century Cyclopean walls built from massive blocks of volcanic rock that you can perch a top for breathtaking views.
There is a small sandy beach in Mandraki which is very popular. Another popular beach is Hohlaki, a black-stone one , on the western side of Moni Panagias Spilianis which is reached by a paved footpath around the headland.

Nisyros is a volcanic Greek island and municipality located in the Aegean Sea. It is part of the Dodecanese group of islands, situated between the islands of Kos and Tilos. Several other islets are found in the direct vicinity of Nisyros, the largest of which is Yiali.
