The Stefanos Crater

The Verdict
A caldera floor of grey ash and yellow sulphur with steam coming out of the ground — the closest you get to standing inside a volcano.
Why go
Stefanos is the big crater at the centre of Nisyros: roughly three hundred metres across, its floor of pale ash and yellow-white sulphur crusts, with fumaroles steaming out of cracks you can walk right up to. The path down from the rim takes ten minutes and the smell of sulphur is constant. Go early, wear shoes you do not mind ruining, and take water — the heat coming off the ground is real and there is no shade anywhere inside.
