The Itinerary in Detail

Starting Point and Logistics

The tour begins at the Old Port of Fira, with an option for hotel pickup—a real plus if you want to avoid the hassle of navigating to the port. The boat departs with a friendly crew, and the journey starts with a scenic sail toward the volcanic island of Nea Kameni.

The Volcano Hike

One of the tour’s main attractions is the guided hike on Nea Kameni. As your boat nears, the rugged cliffs and stark volcanic terrain set a dramatic tone. The guide will lead you along trails, sharing stories about past eruptions and the island’s geological features.

The hike takes about an hour and a half, with a $5 entrance fee payable on-site. It’s worth noting that you should wear comfortable shoes, a sun hat, and bring water—the terrain can be uneven and the sun intense. Reviews highlight that the climb is steady but manageable for those with moderate fitness levels. Always follow your guide’s instructions for safety.

From the summit, the views are spectacular: sweeping panoramas of the caldera, the blue Aegean stretching to the horizon, and surrounding volcanic formations. It’s a highlight for many, especially those interested in geology or just eager for incredible photo ops.

Hot Springs and Mud Baths

After descending, the boat anchors near Palea Kameni, home to the famous hot springs. Here, you’ll have about 30 minutes to swim in mineral-rich waters. The springs are a geothermal treat, known for their therapeutic qualities, and the landscape around is surreal with volcanic hues.

A key detail from reviews is that swimming requires confidence—you’ll need to swim about 30-40 meters from the boat to reach the springs, so if you’re a confident swimmer, it’s a fun and relaxing experience. The waters are warm but not hot, around 23-24°C, which might be a surprise for some expecting steaming baths.

Many travelers enjoy the sense of connection with nature in these waters, and some mention that the sulfur smell is unavoidable but not overwhelming. If you’re pregnant or have certain medical conditions, it’s best to skip this activity; the tour notes this precaution.

Exploring Thirasia

The last major stop is Thirasia, a small, quieter island that feels like a step back in time. Here, you get about two hours of free time to wander through the villages, enjoy a meal, or relax by the water.

However, bear in mind that until May 25th, Thirasia’s port is closed for maintenance, and instead, the boat will stop near the bay for a second swim—so your experience might vary slightly depending on timing. This could mean less time to explore and more time swimming or relaxing on the boat.

Reviews are mixed on Thirasia—many praise its authentic charm and peaceful vibe, with local tavernas serving fresh seafood. Others find the limited options for exploring on foot a bit underwhelming, especially if you’re hoping for more extensive hiking or sightseeing.

Returning to Santorini

After soaking in the views and enjoying the island’s tranquility, the cruise heads back toward Fira, sailing along the coast and passing landmarks like Oia. The return trip is a relaxing way to reflect on the day and soak in the scenery one last time.

What’s Included and What’s Not

The tour includes a guided volcano hike, hot springs visit, and exploration of Thirasia with plenty of free time. The crew is friendly, the boat is kept clean, and foam noodles are provided to support swimmers at the springs. You also have the option for hotel pickup, which makes logistics smoother.

Extras like food, drinks, towels, and swimwear are not included but are available for purchase on board or you can bring your own. The $5 volcano entrance fee is paid on-site, and cable car tickets are not included, so plan accordingly if you’re using transportation from your hotel.

The Experience in Our View

Reviews paint a largely positive picture, with many travelers appreciating the knowledgeable guides, incredible views, and good value. Some mention feeling rushed at times and wishing for longer or more relaxed stops, especially at Thirasia or in the hot springs.

One reviewer noted, “The volcano hike was a real adventure… it was amazing to see the volcanic landscape up close,” illustrating how engaging the volcanic component is. Conversely, a few found the boarding process chaotic or felt the hot springs and Thirasia stops were less impressive than expected, especially when the springs aren’t as hot as some imagine.

The tour’s flexibility and the opportunity to explore independently on Thirasia are definite pluses, giving you a taste of local life away from the busier tourist spots. The price point is quite reasonable, considering the included activities and the scenic beauty.

Final Thoughts: Who Should Consider This Tour?

The knowledgeable guides, combined with the stunning scenery, make this a memorable choice.
