Wet but worth it - Was a wonderful adventure even though we got soaked walking to the volcano on the one day in September it rained. Guides very experienced and did well at keeping everyone informed. Definitely worth the trip. I'd do it again,

Great mix of activities,... - Great mix of activities, although would have liked more time to spend at the hot springs. Be aware that there is quite a bit of walking involved (especially at the first part of the trip at the Volcano). All in all a good day out, well organised by NST Travel and good value for money.

Experience very... - Very interesting experience on the craters of Nea Kameni, swimming in the thermal waters of Palea kameni very special (you need to know how to swim well and recommend rock shoes and black costume), the landscape of Thirassia beautiful (I recommend sunscreen, sneakers and water because the climb is challenging)

Beautiful volcano tour without hectic pace. - The ride was well planned from the time, we hiked with a short guide to the volcano 🌋, at the hot springs you should not expect too much, the water was not hot (lukewarm) and did not look particularly spectacular, but of course the organizer could not do anything. Thirassia was also very nice, does not make the mistake of going down to the harbour to eat, but also goes up the steps to the village when exerted to the panoramic restaurant. Highly recommended. Even the return journey was thought through without hassle, as Oia and Fira were approached very close, and you could take very nice photos. We can definitely recommend the ride.

The explanations in two... - The explanations in two languages (FR/IT) were very interesting but too long for two distinct language groups. So we had to run on the volcano to not miss the boat. We saw almost nothing. The boat was packed. On the other hand very good Price quality ratio.

Santorini volcano tour - The operator was good but not very precise as a guide and the area for 2hrs in Thirassia was nothing much than food Could have spent time returning or a stop in Lia for an hr.

Terrible communication and poor customer service - I booked this activity with a pick up from my hotel. Last minute they decided to change the location spot. We went to the location spot by the time they asked us to arrive. With no clear directions they wanted us to wait on the road for the bus. The bus ended up leaving us. When we tried to call company they kept hanging up on us and sent messages through WhatsApp. I kept asking the last to answer and she kept saying call the platform. This was the worst experience I have ever had in my life. Terrible communication and poor customer service.

Guide did not meet us at designated place so we had to make alternate plans for the day - Communication was challenging. We missed our trip. Recommend you try a different host. Will request refund.
