Santorini Caldera Cruise Tour (Volcano, Hot Springs, Thirassia)

Your journey begins based on your selection: with pickup from Athinios Port, or without pickup from the Old Port of Fira.

The first stop is the volcano, where you’ll have 1.5 hours to hike its rugged trails and explore its unique landscape. A 5€ entrance fee is required to access the volcano. Your tour escort will guide you along the paths, sharing fascinating stories about its history and eruptions. Wear sturdy shoes and bring water for this moderate hike, which rewards you with stunning panoramic views at the summit.

Next, sail to the hot springs at Palea Kameni. The boat will anchor 30-50 meters from the springs, requiring a swim to reach the warm, sulfur-rich waters. This activity is recommended only for strong swimmers due to the distance.

The final stop is Thirassia, where you can explore its charming villages, take in breathtaking views, or savor a delicious meal at a traditional taverna before returning to your starting port.

As your boat nears the volcanic island, its rugged cliffs and stark beauty set the stage for your adventure. Step ashore and begin a guided hike along volcanic trails as your tour escort shares the island’s fascinating geological history and stories of its eruptions.

A 5€ entrance fee is required to access the volcano. Wear comfortable shoes, bring a sun hat, and carry water to stay hydrated during the hike.

At the summit, enjoy sweeping views of the caldera and the Aegean Sea, surrounded by the raw power of nature. Steam vents and volcanic rock formations create a truly mesmerizing, otherworldly landscape.

After taking in the views and captivating stories, return to the boat with unforgettable memories. Always follow your tour escort’s guidance for a safe and enjoyable experience.

The next stop is the island of Palea Kameni, home to the renowned hot springs nestled on its west side. Here, you’ll have 30 minutes to experience the rejuvenating thermal waters, celebrated for their rich volcanic minerals and therapeutic properties.

The boat will anchor approximately 30-40 meters from the springs, and you’ll need to swim this distance to reach the warm, orange-hued waters. Surrounded by stunning volcanic landscapes, this is a rare opportunity to immerse yourself in nature’s healing embrace.

Please note, this activity is best suited for comfortable swimmers, as the swim requires confidence and stamina. For those who venture into the waters, it’s a moment of pure relaxation and connection with Santorini’s unique volcanic energy. Afterward, return to the boat, refreshed and recharged, to continue your unforgettable journey.

The final stop of your journey is the picturesque island of Thirassia, a quiet gem in the caldera untouched by time. Here, you’ll have the opportunity to explore traditional Greek villages, stroll through charming narrow streets, and admire breathtaking views of the Aegean Sea.

For those seeking relaxation, unwind by the waterfront or enjoy a refreshing swim. Food lovers can indulge in a delicious meal at one of the local tavernas, savoring authentic Santorini flavors.
