Experience Santorini’s volcanic wonders on a 3-hour cruise, including hot springs and optional crater hike, with knowledgeable guides and stunning views.
Santorini Port: 3 Hour Cruise to Volcano and Hot Springs
Santorini’s dramatic volcanic landscape is one of Greece’s most iconic sights, and this 3-hour cruise offers an up-close look at its fiery side. Whether you’re a first-time visitor or a seasoned island hopper, this tour provides a balanced mix of adventure, relaxation, and photo-worthy moments. It’s a wonderful way to see the caldera’s volcanic islands without a long day on the water.
What we particularly like is the option to hike up to the crater of Nea Kameni, which adds a memorable, active element to the experience. Plus, soaking in the hot springs offers a unique chance to enjoy volcanic waters that you won’t find on many other Greece excursions. The tour’s price is quite reasonable, considering the included stops and commentary, making it a solid value for those wanting a taste of Santorini’s volcanic heart.
A potential consideration is the hot springs stop, which is limited to just 30 minutes, so if you’re eager for a long soak, you might find it slightly rushed. The boat tends to be crowded in the summer, but there’s enough space to find a comfortable spot if you arrive early. This tour is best suited for active travelers who enjoy a little adventure, scenic views, and don’t mind being on a boat for a few hours.

You’ll meet at Santorini Old Harbor in Fira, at the Santo Star Office, around 10:30 am for a 11:00 am departure. The meeting process is straightforward, but it’s worth arriving early to secure a good seat and avoid the hectic vibe often found in Fira’s port area. The tour includes a live English guide and an engaging audio commentary, which enhances the experience by adding context to each stop.
Once aboard a comfortable wooden sailboat, your cruise begins with a gentle sail into the caldera. From the water, you get a spectacular perspective of Santorini’s rugged coastline—cliffs, whitewashed villages, and the shimmering blue sea provide many photo moments. Reviewers describe the boat as well-equipped, and while summer crowds can make it busy, there’s enough space to find your own spot.
The first main stop is Nea Kameni, the active volcano of Santorini. Here, you have the choice to go on a self-guided hike up to the crater. Reviewers like Abhimanyu note that “the volcano hike is easy and should be a must do for everybody visiting Santorini.” The lunar-like volcanic terrain is fascinating—the black rocks and sulfur vents create a landscape that feels otherworldly.
Keep in mind, the hike is done independently, with no guide accompanying you on the ascent, so you’re responsible for your safety. The walk is moderate and on uneven surfaces, so comfortable shoes are recommended. The experience is about getting close to an active volcano, and many find it inspiring to stand at the crater’s edge and gaze into the fumaroles.
After the hike, the boat moves on to Palea Kameni for the hot springs. Here, you can swim in the sulfur-rich waters and relax on a black sand beach. Reviewers comment that the hot springs are a unique experience, with the waters a little warmer than the sea, and the volcanic minerals believed to have therapeutic qualities.
The hot springs stop lasts about 30 minutes, which some travelers find a bit brief but still enough to enjoy a dip. You can use foam pool noodles provided on the boat for added fun. Note that non-confident swimmers can stay on board if they prefer, and the boat is equipped with life jackets in case of emergency. Some reviewers, like Werner, suggest making the most of the experience by using the pool noodle floats for extra buoyancy and fun.

The cruise ends back at the Old Port of Fira. Many travelers reflect on how the trip offered a perfect mix of adventure and relaxation, with memorable views and educational commentary throughout. The entire experience lasts about three hours and is suitable for most ages, though it involves some walking and optional hiking on uneven terrain.

The tour includes the boat ride, audio commentary, and the optional volcano hike. It also provides foam pool noodles and a hot springs swim stop. Extras like food and drinks are available for purchase onboard, and you’ll need to pay a €5 volcano entry fee in cash. If you want to visit the cable car to get back up from the port, that’s about €6 each way.
Bring comfortable shoes for the hike, sunscreen, a hat, and a towel for the hot springs. Since the tour involves some walking, wearing sunglasses is advised. Be prepared for the crowds in summer, and try to arrive early for the best spot on the boat. For those concerned about getting wet, the boat can be a bit splashy depending on the weather, so pack accordingly.

This cruise offers a genuine look into Santorini’s volcanic side without the need for a full-day commitment. With a reasonable price point of around $33.88 per person, it packs in enough adventure and scenery to satisfy most travelers. The self-guided hike allows for flexible exploration, and the hot springs provide a relaxing counterbalance.
Reviewers like Jessica and Werner mention how organized chaos at the port can be a minor hassle, but the fun and spectacular views make it worthwhile. The knowledgeable guides and engaging commentary help transform the water ride from just a boat trip into an educational, memorable experience.
This tour is ideal for adventurous travelers who want a snapshot of Santorini’s volcanic activity, families ready for a quick but fun outing, and anyone interested in photography—the views and landscape are stunning from every angle. It’s less suited for those with mobility issues or who prefer long, leisurely baths, but overall, it’s a well-rounded experience that delivers on value and authenticity.

In essence, this 3-hour cruise to Santorini’s volcano and hot springs offers a focused, engaging, and cost-effective way to see some of the island’s most striking features. It strikes a good balance between active exploration and relaxing dips, wrapped in the scenic beauty of the caldera.
The self-guided volcano hike is a highlight—an opportunity to stand at an active volcanic crater, imagining the fiery forces that shaped the island. The hot springs are a quirky, volcanic treat, even if the experience is a quick dip rather than a long soak. The views from the water, coupled with commentary from knowledgeable guides, elevate the trip beyond a simple boat ride.
This tour is best suited for travelers who enjoy light activity, stunning scenery, and a touch of adventure. It’s not for those seeking a lengthy, luxury hot springs experience, but for a quick, authentic taste of Santorini’s volcanic soul, it’s hard to beat.
