Kardamaina to Nisyros: the volcano day trip

Nisyros is a small round volcanic island across the water from Kos. Boats from Kardamaina harbour reach it in about an hour, and a day trip fits the crater, a village and lunch.

The easiest way to see Nisyros from Kardamaina is a day-trip boat that leaves the harbour in the morning. Tour operators quote roughly 45 minutes to an hour each way, and most trips leave about four to five hours on the island.

What you see

  • The crater (Stefanos). You walk down onto the floor of a volcanic caldera, a pale, sulphur-stained basin with steaming vents. It is smaller than people expect, and the smell of sulphur is part of the experience.
  • Mandraki. The main village, with whitewashed houses, flower-filled lanes and the Panagia Spiliani monastery above the harbour.
  • Nikia. A village on the crater rim with views down into the caldera and a small square for a coffee.
  • Emporios. A village on the rim, on some itineraries.

Go with sturdy shoes and a hat. The crater has little shade, the ground is rough and, near the vents, warm. In July and August, ask for the earliest trip.

Planning tips

  • Trips depend on the sea. If the wind is strong, boats can be delayed or changed, so don’t schedule the trip on your last day.
  • Bring cash for coffee or souvenirs in the villages, since small shops may not take cards.
  • Combine it with a quiet beach day the next day: see Kardamaina beaches.

Frequently asked questions

How long is the boat from Kardamaina to Nisyros?

Tour operators quote about 45 minutes to 1 hour each way on the day-trip boats. Local scheduled boats can take longer, so check which kind of boat you are booking.

Is the Nisyros volcano active?

It is a dormant volcano with active fumaroles: steam vents and sulphur smell inside the crater. Its last recorded hydrothermal eruptions date from the 19th century. Follow the signs and the guide's instructions.

What should I wear on Nisyros?

Closed, sturdy shoes because the crater floor is rough and warm in places, a hat, sunscreen and water. Take a light layer for the boat.

Can I go to Nisyros independently?

Yes, by boat from Kardamaina or from Kos town, with a taxi or bus on the island. A guided day trip is simpler because the boat and island transfers are included.
