Boiler beautiful place and adventures per thousand - A friendly city with the tourist beautiful places and a variety of panoramas, to move by boiler for a thousand pesos the groups take you anywhere all day until very late, for 1500 pesos you arrive in minutes to English bay, I recommend eating by boiler, if you want to know exceptional places the Geotourism tour we did of dunes and astronomy was first level... to leave luggage you can do it in the terminal Casther and from there are buses to Copiapo, to reach beach the virgin you can take tour or make a beautiful but tiring route from old port...beautiful city and surroundings

Definitely recommend - Great day out! Would highly recommend. This one does the volcano hike first and then the swim in the sea / thermal pool. Our guide was very informative, which really added to the experience. The stop off for lunch was lovely, and amazing views of the caldera and islands throughout. Very good value excursion.

Beautiful Day Touring The Caldera - This tour was a great way to visit the islands inside the Santorini Caldera. The boat was comfortable. The bathrooms were clean and the crew were pleasant. We didn't walk up to the Volcano because it was a steep climb so we remained on the boat. I would recommend this tour. We are older and the company picked us up close to our accommodation. They were prompt and courteous.

Great day! - Superb family day, with 2 children aged 6 and 8 years. We took the boat to the old port of Fira, leaving at the exact time. 1st stop at the Volcano, with explanation about the quality geological activity with Yann in English (and in French because there was quite a lot of French), we then had time to go up and take pictures. Very interesting. 2nd stop at the hot springs: water at 23°C while the sea is at 19°C, about 30 people bathed. Then 3rd stop in Thirassia: 2h break: lunch, or climb to the village of Manolas Return by boat under Oia and along the coast; return a little before 16:30. A very good day!

Skip this tour - This is a misleading tour. We enjoyed the history and the hike up to the top of the volcano. The tour guide was very knowledgeable; the volcano experience is the reason I didn't give this tour 1 star. The "Hot Springs" and Thirassia were a disappointment. The day previous to our tour, a local informed us that the Hot Springs weren't hot due to the volcano being dormient. Due to this, I reached out to Viator and received the response that was captured in the picture I attached. When we got to the Hot Springs portion of this tour, the locals were absolutely correct. The tour guide informed us it was around 23 C (73 F) and referred to them as "warm" springs. It was highly disappointing. The last stop was also a disappointment. We were taken to Thirassia for 1.5-2hours. There were only a few restaurants at the bottom of the island where the port was and were told we could hike to the top if we chose. There wasn't enough time to do both eating and exploring. We were loaded up in the boat to go back to Santorini and it took 1.5hrs for them to get us back even though it was all within viewing distance. They took the long way to get there, ultimately to drag this tour out to a full 6 hours. It was completely unnecessary and most people were asleep or disengaged. Overall, I do not recommend. Find a tour that takes you to only the volcano and save your time and money.

PASSAGE FRUSTAGE THAT HAS NOT HAPPENED - I have traveled for years and never stopped taking a walk. It turns out that on the date of the tour, we arrived at the matched place. After some time we decided to call the contact phone, because no one showed up. Surprisingly, we were informed that the staff had already passed through the meeting point. So, we're wondering how that happens??? In short, we complained, we were informed that they sent an email, which by the way, to this day we are tempted to locate. No de facto connection to the tour contractor was made or recorded by us (before, during, or at the time we allegedly did not show up). It was frustrating! And we also received a message via WhatsApp at the end telling us to enjoy the trip and didn't even talk about the return of the amount. As it was the first time we bought tours through this site, I DO NOT indicate. Always buy from official websites like Getyourguide or Civitatis. Andreia Amaral
