Cruise an hour from Kos to Nisyros, then follow a short transfer to the Polivotis crater where sulfur vents and basalt ridges reveal the island’s volcanic past. This full-day tour blends a dramatic geological walk with time in Mandraki’s compact port village.

The trip begins in the harbor air off Kos, where a one-hour ferry pushes through Aegean blue and delivers travelers to a compact island that still smells of sulfur and sea. Disembarking at Mandraki, a short transfer climbs into the island’s volcanic heart: the Polivotis crater. On the rim the ground feels alive — faint hisses and warm puffs remind you that the island is geologically young and still breathing.

Wildlife
History
Nisyros is volcanically young; Polivotis and nearby craters were formed by repeated eruptions and local basalt has been used in construction for centuries, shaping village architecture.
Conservation
The island’s fragile scrub and fumarole zones are vulnerable to trampling; stick to trails, avoid collecting rocks, and support local waste-reduction efforts.
Reserve your spot on the Full-Day Tour to Nisyros The Volcano Island today and enjoy a trusted, highly rated experience designed to help you make the most of your adventure.
Sturdy footwear
Wear closed shoes with good tread—volcanic scree and uneven rock demand stable soles.
Hydrate and shade up
Carry at least 1–2 liters of water and a hat—sun can be intense on exposed crater rims.
Respect fumaroles
Stay on marked paths near vents; gases can be hot and concentrated in low spots.
Time your photo stop
Plan photos in Mandraki or after the crater visit—service and shade are limited at the rim.
Sturdy hiking shoes
Provides traction and ankle support on loose volcanic rock and steps.
Sun hat and high-SPF sunscreen
Protects against strong Aegean sun during exposed crater walks and time in Mandraki.
