This six-hour boat tour around the Santorini caldera includes hiking, swimming, and island exploration. The tour starts at either Athinios Port with pickup or the Old Port of Fira without pickup, depending on the chosen option. The first stop is the Santorini volcano, where guests have about 1.5 hours to hike its volcanic trails with a guide who explains the geological history and eruptions. A 5€ entrance fee is required for access. Participants should wear sturdy shoes, bring water and a sun hat. After the hike, the boat sails to the hot springs at Palea Kameni, where visitors can swim in warm, sulfur-rich waters. The boat anchors 30 to 50 meters from the springs, so reaching them requires a swim recommended only for strong swimmers. Foam pool noodles are provided for support. The final stop is the island of Thirassia, where there is time to explore villages, walk along narrow streets, enjoy views of the Aegean Sea, swim, or eat at a traditional taverna before returning to the departure port. The tour escort is present throughout to guide and assist. Food, drinks, towels, swimwear, entrance fees, and cable car tickets are not included.
