An In-Depth Look at the Santorini Caldera Cruise

Setting Sail from Athinios Port

The adventure begins at Athinios Port, the main gateway for boats exploring Santorini’s volcanic landscape. Depending on your booking option, you’ll either meet your group at a nearby hotel pickup point or head directly to the port. Reviewers mention that the bus transfers are smooth, with pickup times early in the morning—around 8:25 to 9:00 am—so arriving on time is key to a stress-free start. The boat itself is a traditional wooden vessel, which adds authenticity to the experience. Expect to share the space with others, as the tour is popular, but the boat’s layout generally allows for comfortable seating.

Exploring Nea Kameni: The Still-Active Volcano

The first stop is Nea Kameni, home to the island’s still-smoking volcano. This is the highlight for many visitors—an up-close encounter with geological power. The walk to the crater is unguided, which means you’ll be responsible for your own safety but also for taking it at your own pace. Reviewers note that the hike is manageable, but some mention that you should wear decent walking shoes and bring water, especially during warmer months.

Guests have appreciated the opportunity to witness the eruption vents and volcanic landscape, which offers stunning panoramic views of Santorini. One reviewer, Mingxia, praised the trip as “very effective and fun,” especially highlighting the chance to see a live crater. Another reviewer, expressing concern about the walk, suggested wearing pants as the wind can whip sand into your legs—definitely good advice for comfort.

Soaking in the Hot Springs

After the volcano, the boat takes you to Palea Kameni, where hot springs await. The high sulfur content is said to have healing properties, and the waters are a peculiar shade of mineral-rich greenish-yellow. Many reviews mention that the hot springs aren’t very hot—more lukewarm, especially in September—but still a fun and soothing part of the trip.

A couple of practical notes: the water may stain light-colored swimwear, so packing darker swimsuits is wise. Also, some guests prefer to stay on the boat if they’re not confident swimmers or if weather conditions turn windy. The 30-minute stop is enough for a quick dip, but it’s not a long soak, so don’t expect a spa experience.

More Great Thing To Do Nearby

Second Swim: Thirassia Island

Next, the tour stops at Thirassia, a smaller, traditional island that offers an authentic Greek vibe away from the tourist-heavy spots. The second swimming break here is generally praised, with reviewers describing the calm waters and scenic surroundings as “breathtaking.” You get about 30 minutes to dip into the Aegean, explore a little, and soak in the tranquil atmosphere.

Reviewers have noted that Thirassia’s quiet charm makes it a perfect spot for a relaxed swim or some quick sightseeing. It’s a welcome contrast to the volcanic terrain.

Scenic Caldera Sailing and a Magical Sunset

Following the swims, the cruise takes you around the majestic volcanic cliffs and whitewashed villages perched above the sea. The views are often described as “spectacular,” and the calm sailing makes for a relaxing experience.

For many, the highlight is the sunset in Oia. If you’ve booked the extension, you’ll disembark here for 2-3 hours of exploring this world-famous village. Reviewers love the winding streets, the whitewashed houses, and the golden hues reflecting off the buildings. Just a tip from reviews—Oia gets very crowded at sunset, so arrive early to secure a good spot.

Ending the Day and Returning to Santorini

The tour concludes back at Athinios Port around 3:45 pm, giving you ample time in the afternoon for additional sightseeing or relaxing. If you’ve opted for the Oia extension, you’ll be transported back after sunset, feeling like you’ve experienced the best of Santorini’s natural beauty and charming villages.

What’s Included & What You Should Know

The tour is priced around $28 per person, which is remarkably affordable considering the inclusions. It covers roundtrip bus transfers, a local guide, audio commentary, visits to the active volcano, hot springs, and Thirassia, plus foam pool noodles—a fun touch for floating around.

Additional costs include volcano entrance fees (€5) (cash only), cable car tickets (€10 each way), and drinks available onboard. The tour is flexible, with options to extend to the sunset in Oia, making it suitable for different types of travelers.
