Caldera's Boats

Our company has been organizing special guided tours for Santorini's visitors with traditional wooden boats for 47 years. The first tour was in 1968 with a small caique whose name was Saint Nikolaos. Captain Manolis was the person that started these small tours and he is one of the shareholders of our company. The first travel agency opened in 1947.

Our fleet today consists of 8 wooden boats with diesel engines and a highly experienced crew. We invite you to an extraordinary exploration of Santorini from a different perspective. Our travel agencies, one in Fira and one at the old port, are available for you every day. You can easily book online your private or group boat cruise and enjoy the unique opportunity to see the active volcano from up close, swim in the hot springs or make a romantic sunset cruise. The views of Caldera rising up to 450 meters above sea level dotted by picturesque settlements of white Cycladic houses are majestic. It is then that you will realize that no journey to Santorini can ever be complete without a leisurely boat ride.

Must do when in Santorini

Amazing trip! The tour was very interesting and everything was perfect!

Giorgio G. United Kingdom, 30 Jul 2021
Ok but exhausting

The boat is nice and comfy but the trip is a bit wasted. Most of the time is spent on the desertic volcano and there is nothing to do there besides a walk under a scorching sun. The second leg is spent swimming in the thermal pools and that is the trip's highlight.
