From Old Port:Volcanic Islands Boat Trip & Hot Spring Visit

Exploring Santorini’s volcanic landscape by boat offers a chance to see some of the most dramatic scenery in the Cyclades. This volcanic islands tour takes you from the Old Port of Fira to the fiery craters of Nea Kamenis, the warm waters of Palea Kamenis, and the charming village of Thirassia. It’s a compact adventure that packs in natural beauty, unique geological sights, and a relaxing swim—all in just a few hours.

What I appreciate most about this experience is how accessible and straightforward it is. The boat departs twice daily from Fira’s Old Port, giving flexibility for morning or afternoon plans. The crater hike brings you close to the volcano’s active features, offering a rare glimpse at the raw power beneath the island. Plus, the hot springs visit promises a soothing swim in thermal waters formed over volcanic eruptions, adding a healthful and fun element to the trip.

One point to keep in mind is that there’s a small entrance fee of €5 for the volcano and an optional €6 cable car ride to get down to the port—these aren’t included in the ticket price. Also, travelers wanting to take full advantage of the hot springs should bring a towel, as it’s not included. The tour offers excellent value for those who want a quick yet immersive look at Santorini’s volcanic heart.

Experiencing Santorini’s Volcanic Heart

Taking this boat trip from the Old Port of Fira is a brilliant way to see Santorini’s volcanic core without the hassle of arranging multiple excursions. The boat departs twice daily, usually around 11:00 or 14:15, giving you flexibility based on your schedule. The meeting point is straightforward—just head to the Santo Star travel office at Gialos, the bustling port area just below Fira. After a short cable car ride (or a walk down the 587 steps for the energetic), you’ll be gazing at the caldera cliffs as you board your boat.

From the moment the vessel pulls away from the lively port, the scenery begins to impress. The views of the towering cliffs and cave houses make it clear why Santorini’s landscape is so iconic. The boat is typically well-sized, and while not a large cruise, it’s comfortable enough for a small group, fostering a friendly atmosphere.

The highlight of the tour is the visit to Nea Kamenis, where you can hike to the crater’s edge and peer into the bubbling, active vents. You’ll love how close you get to the volcanic activity—it’s raw, powerful, and dramatically scenic. The guides are knowledgeable, often sharing fascinating details about the volcano’s eruptions and formation, making it more than just a pretty view. One review mentions how the crew was “attentive,” adding a layer of comfort to the adventure.

Walking on the Crater and the Volcano

The 1.5-hour stay at Nea Kamenis is the core of the experience. You can choose to stick with the group or follow the trail to the top. The hike isn’t overly strenuous, but sturdy shoes are recommended as the terrain can be uneven and volcanic ash-covered. The active craters explode with fumes and heat, giving you a feeling of being at the very edge of creation.

One traveler, Aurelie, called the excursion “top-notch” and praised the “attentive crew,” which makes such an active part of the trip feel safe and well-organized. You’ll love observing the landscape where volcanic eruptions have shaped the island for thousands of years, creating the surreal black lava fields and jagged formations.

The Hot Springs at Palea Kamenis

After the volcano, the boat drops anchor at Palea Kamenis, home to the famous hot springs and mud baths. The waters here are heated by volcanic activity, and the temperature can vary depending on the season but generally feels warmer than the surrounding sea. Spending 30 minutes swimming or relaxing in these thermal waters is both fun and restorative.

Bring your towel—this isn’t included—and be prepared for a few volcanic mud patches, which are believed to have skin-beneficial properties. The waters are a bit cloudy and earthy, but many find the experience uniquely soothing. One review highlights the “healthy and relaxing swim,” and the natural mineral composition adds a memorable, authentic touch to the trip.

Visiting Thirassia Village and Returning

If time allows, some tours include a brief stop at Thirassia, a lovely village that offers a glimpse into traditional island life. This isn’t always a formal part of the itinerary but can be a charming addition if scheduled. The boat then heads back to Fira’s Old Port, where you can either hop back up via cable car or climb the steps—many find the walk a scenic way to end the day.

Price, Logistics, and Practical Tips

The tour costs are quite reasonable considering the experience; however, remember there are small extra fees—€5 for the volcano entrance (payable on site) and €6 for the cable car if you choose to avoid the stairs. Since the boat trip lasts about 3 hours total, it’s perfect for travelers with limited time but eager for a natural highlight.

Bringing a towel is essential since swimming in the hot springs is a key feature. Towel rentals are not included, so pack accordingly. The tour is conducted in English, and guides are knowledgeable and friendly, making the experience accessible for most travelers.

The meeting point at Gialos is convenient; just take the cable car from Fira or walk down the steps. The boat remains at the port for the entire duration, so you won’t feel rushed.

Who Should Book This Tour?

This trip is ideal for those who want a quick, immersive look at Santorini’s volcanic scene without multiple stops or long hikes. It’s great for couples, small groups, or solo travelers interested in geology and scenic boat rides. People who enjoy natural thermal baths and spectacular views will find this a worthwhile addition to their Santorini itinerary.
