Description
"The best value-for-money excursion cruise in Santorini" Set sail from Ammoudi Port cruising along the coastline and visit the two most iconic sights of the island. Get to hike the volcano and swim at its Hot Springs, where you can treat yourself with a natural spa in thermal mixed with volcanic mud waters. One of the best-kept secrets of Santorini is the islet of Agios Nikolaos, next to Ammoudi port. One can reach this only by a short and quite tricky hike or by boat. You will enjoy a short swim and maybe take the opportunity and take a memorable dive from the cliff. The Motor Boat is 10m in length, spacious cruising hull boat with one 400 HP engine. It is constructed and designed to provide comfort, with its exterior shaded area and its interior seating space with a table and WC.

Volcano tour
We had an amazing trip to the volcano and hot springs !Private trip with great guides! They gave us lots of information along the way and we were able to come and go when we were ready! We would book again if we come back to Santorini!

Amazing Santorini Sunset Moment
What a wonderful night. We did the sunset private boat ride for a family of 4. It was too hot to hike the volcano, so we opted for swimming in the bay followed by the hot springs. What a strange and awesome experience to feel the melding of hot and cold waters all around your body. George, our guide, was informative, friendly, polite, and great company! So much so, we invited him to visit us in Colorado. We learned so much about the volcanos, the island of Thirasia, where our guide and family still lives. We all got off that boat and said that was worth every penny! And it was. Thank you for the opportunity to learn about Santorini, Thirasia, and your culture. Eternally grateful for this experience!

Excellent adventure
Wonderful trip! Beautiful scenery, educational, and friendly service!

Family charter
We booked a private 3-hour tour with Spiridakos and it was genuinely one of the highlights of our Santorini trip. We were a family of three — two adults and an 8-year-old — and Nick and George on the Oia looked after us brilliantly from start to finish. The hot springs were spectacular and Nick and George made sure our son David had the best time — patient, fun, and clearly experienced with families. The whole trip felt personal rather than transactional, which is exactly what you want from a private charter. The boat itself was immaculate, the snorkelling gear was all provided, and the crew’s knowledge of the caldera and volcano was excellent.

Discover the amazing waters in Santorini
Last minute booking but an awesome experience! Great boat, great crew and amazing time! We went swimming in 4 different locations including the Caldera volcano waters and a cave in one of the rocky beaches! Great way to spend the afternoon in Santorini.

Morning tour
We had an amazing time with George and Hamde. They were very attentive and even took us to have some ice cream in Thirassia. We will 100% recommend.

Perfect day trip on the water
We had a great time with the captain and 1st mate. He took us to some hidden gems and gave us extra time. We did the 1:30pm tour and had the volcano hike to ourselves until we came down for the last 10 min we started to see others. The water was very cold in June so be prepared! But it was nice to have someone hose you off and be ready to wrap you up in a warm dry towel when you hop back in to the boat. They were very gracious! Highly recommend!!

Just right!
It was a lovely cruise around the island. We enjoyed some swimming/snokelingl and then the natural Hot Springs near the volcano. It ended with a gorgeous sunset. Exactly what we needed. We particularly liked that it was a private tour for our family. We were not interested in a booze cruise, so this was perfect.
