Walk Nisyros crater from Kos, taste the sulfur air, explore Mandraki and Panagia Spiliani, and return to Kardamena same day.

“What an amazing experience to walk in the crater of a volcano. From start to finish the trip was amazing and well worth the money. Martha our English speaking guide was very knowledgeable. The only downside was the coach was not air conditioned which was made worse by people not sticking to the departure times, don’t be that person that makes the coach late. The walk down to the crater was fine but coming back up was quite hard work as it was so hot which made it hard to breathe. There is a small cafe at the entrance to the crater selling drinks and snacks and there are toilet…”

See Nisyros from Kos with a guided volcano walk, blue-and-white Mandraki, and Panagia Spiliani monastery, plus a relaxing boat ride.

“This was the second time we’d done this trip It was well organised The Island is beautiful Unfortunately the recommended Taverna was very poor. The food was lukewarm and disappointing. The boat trip home was horrendous. Very choppy , with lots of swell . We were completely soaked and it was a scary experience. We appreciate that the sea conditions were not something that could be avoided, but some prior warning would have been appreciated, so we were forewarned. The conditions at sea must have been anticipated given that all families with children were advised to sit downstairs and the front of the boat upstairs had been cordoned off .”

Pirate boat trip from Kos with swims at Pserimos and Plati, a Kalymnos town visit, and onboard souvlaki lunch, plus slide fun.

“We had a very lovely day. Nice first stop at the beach of Pserimos. Then you get a nice meal. Nothing fancy but good enough to get through the day. The second stop at Kalymnos was good but we liked this one the least. The last stop was very fun, here you can swim in te open sea (there is a diving platform and a waterslide). At the boat is good music, nice drinks and the guide is very good at his job to entertain everyone. We enjoyed our day very much. If you are in Kos this is a must do.”
