Santorini Volcano, Hot Springs Adventure

If you’re dreaming of experiencing Santorini’s volcanic landscapes, this tour offers a taste of its fiery core and tranquil waters all in one day. From sailing around the caldera to soaking in natural hot springs and wandering through charming villages, there’s plenty to love — especially if you enjoy a mix of nature, culture, and breathtaking views.

What we really appreciate about this experience is its balance: it offers a well-rounded glimpse of Santorini’s volcanic activity and local life without feeling overcrowded or overly complicated. Plus, the opportunity to enjoy Oia’s legendary sunset adds that perfect ending to a day of exploration.

That said, it’s worth noting that some parts of the tour, like the hot springs, can be a bit underwhelming if you’re expecting something hot or luxurious — the waters are only a few degrees warmer than the sea, and facilities are basic.

Getting to Know the Tour

This tour is a fantastic way to see Santorini’s volcanic side without the hassle of planning each detail yourself. Starting from the Old Port of Fira, you’ll hop onto a boat that takes you out into the caldera, where the real magic begins. The boat, often not overly crowded, offers a comfortable vantage point for photos and relaxing in the sun.

One of the main highlights is Nea Kameni, the active volcano. The guided walk up to the crater is a chance to get up close to this rugged, fiery landscape. Many reviewers mention how the guides bring the volcanic activity to life with their commentary, making the hike both educational and engaging.

Next, the journey moves to Palea Kameni for a swim in the hot springs. While the waters are sulfur-rich, they’re only slightly warmer than the surrounding sea, which surprises some visitors expecting something hotter. The experience of swimming in these natural waters, however, remains a unique treat, and many enjoy the novelty of it. Just keep in mind that the facilities are basic — no fancy changing rooms or showers, and the water can discolor light-colored swimwear.

The boat then heads to Thirassia, a lesser-known spot where you can wander through a peaceful village, enjoy a relaxed lunch, or simply soak in the quiet charm of a traditional Greek island. Many travelers, as one reviewer put it, find Thirassia “delightful,” and appreciate its unspoiled ambiance away from the tourist crowds.

For those opting for the extended tour, a bus trip takes you to Oia, famous for its postcard-worthy views and spectacular sunset. Spending 2-3 hours wandering the streets, browsing local shops, and watching the sky change colors is often the highlight of the day. Reviews praise the ease of navigation, with guides giving clear advice on returning.

The tour wraps up with a comfortable bus ride back to your starting point, leaving you with vivid memories of Santorini’s natural forces and peaceful corners.

Hot Springs Stop

Next, the boat moves to Palea Kameni for about 30 minutes of swimming — a highlight for many. The waters are sulfurous, which can leave a slight discoloration on light clothing, and the experience involves swimming from the boat to the springs. Some reviews mention that the springs aren’t particularly hot, but the novelty of floating in natural mineral waters is worth it. Be prepared for some waiting, as others often take their time to jump in or swim back.

Thirassia Exploration

The island of Thirassia offers a peaceful break, with options to walk around, explore the narrow streets, or enjoy local cuisine. Many travelers appreciate this stop as a quieter, more authentic Greek island experience — a sharp contrast to the busier Santorini spots. The free time—often around two hours—gives you enough opportunity to wander, take photos, or find a cozy tavern.

Oia and Sunset

For the longer tour, an additional bus ride takes you to Oia, about a 2-hour visit. You’ll love the picturesque streets, the iconic blue-domed churches, and the panoramic views. As sunset approaches, the town fills with visitors all eager to witness the sky turn a blaze of colors. Multiple reviews mention how well-organized this part is, allowing ample time to explore and soak in the scenery.

Return Journey

After sunset, a bus takes you back to your original meeting point. The ride is usually smooth, and most travelers find the day well-paced and fitting for a full-day adventure.

Practical Tips Based on Reviews and Experience

• Timing: The tour is flexible, but if you’re keen to maximize hot springs time, try to swim early, as waiting for everyone to jump in can cut into your soak.
• Clothing: Bring a change of clothes and a towel, especially if you plan to swim. The facilities are basic, and you might want to change before heading to Oia.
• Sun Protection: The boat and open areas mean lots of sun — pack sunscreen, hats, and sunglasses.
• Footwear: Comfortable shoes for walking and hiking will make the volcano walk more enjoyable.
• Booking: The tour offers free cancellation up to 24 hours in advance, making it flexible if your plans change.
• Group Size: While the boat generally isn’t crowded, larger tours might feel busier, so consider that if you prefer a more intimate experience.
