Discover Santorini’s volcanic landscapes and hot springs on this 3-hour cruise from Fira Old Port, with guided hikes, hot spring swimming, and stunning views.
If you’re seeking an accessible way to explore Santorini’s volcanic terrain and thermal springs without a full-day commitment, the Santorini Volcano and Hot Springs Cruise Tour offers a compelling option. Priced at $34.83 per person, this half-day tour lasts approximately 3 hours and departs from the Fira Old Port. It combines a guided hike up Nea Kameni, an active volcano island, with time to relax at Palea Kameni’s natural hot springs. The tour is especially suited for those who appreciate a mix of scenic views, light physical activity, and unique natural features, all wrapped into a well-priced experience.
While the tour provides stunning visuals and insightful commentary, it also requires some moderate physical fitness—particularly for the volcano hike and swimming to the springs. The tour’s strengths lie in its expert guides, accessibility, and the opportunity to escape crowds by visiting uninhabited islets. However, a $5 entrance fee for the volcano, the need for your own towels and swimwear, and the physical demands of swimming and hiking are factors to consider.


The tour begins at the Fira Old Port, where a boat awaits to take you to the volcanic islands. The departure point is easy to reach, and the boat ride itself offers views of the rugged island cliffs and caldera. The boat is comfortable and not overcrowded, with refreshments available on board, including a minibar for water and snacks.
In most reviews, the smooth departure and scenic ride set a relaxed tone for the adventure ahead. The group size can be up to 150 travelers, making it lively but manageable. It’s advisable to arrive 45 minutes early to avoid delays, especially if using the cable car or walking down the port stairs.

The highlight of the trip is the guided hike on Nea Kameni, where the volcanic landscape is strikingly different from the rest of Santorini. As the boat approaches, the rugged cliffs and stark terrain hint at the power beneath the surface. The guide shares fascinating details about the volcano’s eruptions and geological features.
Once ashore, the walk along volcanic trails takes about 1 hour 30 minutes, covering rough terrain that requires comfortable shoes, preferably closed-toe footwear. For $5, visitors can pay for entry to the volcano’s crater and enjoy the panoramic views from the summit, including sweeping vistas of the Aegean Sea.
The landscape here is otherworldly, with steaming vents, volcanic rocks, and a landscape shaped by ancient eruptions. The ascent is rewarding but can be physically demanding, especially in hot weather. Guides emphasize safety and encourage following their instructions closely.

At the top of Nea Kameni, visitors are greeted with breathtaking views of the caldera and surrounding islands. The dizzying heights and raw volcanic features make this a memorable spot for photography and sightseeing. The steam vents and volcanic formations add to the dramatic scenery.
This part of the tour caters most to those comfortable with uphill walking and exposed terrain. The viewing platform at the summit provides a chance to appreciate nature’s force and capture photos. Guides explain the geological history, making the ascent both educational and visually stunning.

The boat then moves to Palea Kameni, home to thermal springs that are rich in sulfur minerals. Here, around 30 minutes are set aside for swimming—an activity best suited for strong swimmers who feel confident in the water.
The boat anchors 30-40 meters from the springs, requiring swimmers to reach the warm waters by swimming. Foam noodles are provided to assist those who want support, but swimming stamina is necessary. The orange-hued waters create a striking contrast with the surrounding volcanic landscape, offering a unique experience of natural healing.
The springs are not very hot, and the experience involves some cold swimming after the thermal waters. Those with medical conditions or who are pregnant are advised to avoid swimming. The time allocated is enough for a refreshing dip and relaxation.

After the hot springs experience, the boat heads back toward Fira Old Port. The return leg offers one last chance to enjoy scenic views of the caldera and volcanic islands. The boat ride is generally smooth and well-paced, allowing travelers to unwind and reflect on their geological adventure.
The tour concludes at the Old Port of Fira, where you can continue exploring or head to other parts of the island. The entire experience is designed to fit into a half-day, leaving the rest of your day free for dining or additional sightseeing.

This tour involves moderate physical activity, including uphill hikes on uneven volcanic terrain and swimming in natural waters. Comfortable, closed-toe shoes are recommended for the hike, and swimwear plus towels are essential for the hot springs. The hot springs are not very hot, so visitors should temper expectations if seeking intense thermal baths.
It’s also wise to bring water, sunscreen, and a sun hat to stay protected during the hike and boat ride. The guide’s insights make the hike more engaging, but guests should be prepared for some exertion. The tour is especially suitable for those who enjoy active experiences and scenic landscapes.

The Old Port can be chaotic, with crowds and donkey traffic that some find disturbing. Using the cable car can help avoid the stairs and animal welfare concerns. The tour itself is not designed for mobility-impaired guests, given the uphill trails and swimming requirements.
Anyone not comfortable with swimming or moderate hiking may find parts of the tour challenging. The group size can reach up to 150 people, but the experience remains manageable thanks to the guides’ professionalism.

This Santorini Volcano and Hot Springs Tour delivers a combination of natural beauty, physical activity, and educational insight at an affordable price. The guides’ expertise and stunning views are frequently praised, along with the well-organized logistics.
However, those looking for luxurious thermal baths or easy access should consider the physical demands and the swimming requirements. The hot springs are a highlight for adventurous spirits, but the cold water swim and climb are not for everyone.
