Caldera Morning Cruise With King Thiras Boat

If you’re planning a trip to Santorini and want to see its volcanic origins up close, the Caldera Morning Cruise with King Thiras Boat could be just what you’re after. This tour promises a full day of island-hopping, natural hot springs, and spectacular scenery—an authentic way to experience the island’s raw beauty beyond the usual viewpoints.

What makes this tour appealing? First, we love how it combines both scenic sailing and active exploration — climbing a still-active volcano and swimming in warm springs. Second, the fact that it covers three different islands in one trip makes it a solid value, especially if you’re keen to get a sense of the broader caldera area.

That said, a potential consideration is the size of the group. With the boat accommodating up to 250 travelers, you might find it a bit crowded, especially during peak season. Also, keep in mind that the volcano entrance fee of 5 euros isn’t included in the ticket price, so budget accordingly.

This cruise is best suited for travelers who enjoy outdoor activities, scenic boat rides, and learning about volcanic history. If your ideal day involves a mix of adventure and relaxation with a few good photo ops, this tour could be right up your alley.

What to Expect from the Itinerary

Starting at the Port

The day kicks off with a comfortable bus transfer from your hotel or designated meeting point to Athinios Port. From there, the three-masted sailing ship awaits, ready to introduce you to some of Santorini’s most iconic sights from the water. The boat, operated by Kamari Tours, is described as large—so don’t be surprised by the size—and it’s well-equipped for a day out at sea.

First Stop: Santorini Volcano (Nea Kameni)

The main highlight here is the volcanic crater, still considered active. Once at Nea Kameni, you get about an hour to ascend the soil path and get close to the crater. The opportunity to stand near an active volcano is fascinating and adds an adventurous element to the trip. Keep in mind, admission tickets (5 euros) for the volcano are not included, so you’ll need cash or card at the ready.

According to reviews, guides are knowledgeable and explain the volcanic activity clearly, making this stop both educational and exciting. We loved the way the guide shared stories about the island’s formation and volcanic history, which really brought the landscape to life.

Second Stop: Palea Kameni Hot Springs

After the volcano, the boat sails to Palea Kameni, home to natural hot springs. The boat stops about 50 meters from the springs, allowing you to dive into the warm, mineral-rich waters or just relax and enjoy the view. The hot springs are a coveted feature, offering a unique swimming experience. Be aware that admission is included in the tour, but you can expect to share the space with other travelers on the boat.

One reviewer mentioned that the water was quite warm but not hot enough to burn; it’s the kind of experience that’s both soothing and fun. Plus, the bright green waters are oddly captivating and perfect for photos.

Third Stop: Thirasia Island

The third stop takes you to Thirasia, a quieter island that was once part of Santorini before the volcanic explosion reshaped the landscape. Here, you’ll have about two hours to explore, swim, or enjoy a seaside lunch. The village of Manolas, with its winding steps and traditional houses, offers a glimpse into local life away from tourist-heavy spots.

Many travelers appreciate the free time here, since it’s an opportunity to strain your legs with a walk or just unwind by the water. The reviews mention that the island has beautiful scenery and a laid-back vibe, making it a nice break from the busier parts of Santorini.

Return Journey & Views of Oia

As the boat heads back to Athinios, you’ll cruise past Oia, often considered the most picturesque village on the island. It’s a perfect moment to capture photos of the cliffs and the whitewashed buildings perched on steep slopes—views many travelers find unforgettable.

Back at the port, the bus awaits to take you back to your hotel or starting point, completing your day with a lot of memories and some fantastic pictures.

Practical Details and What You Should Know

Duration & Timing

The tour lasts about 7 hours, starting at 10 am. This means you’ll get a good chunk of the day to enjoy the sights and activities without feeling rushed. The start time is convenient, especially if you like to sleep in or explore on your own in the morning.

Cost & Value

At $60.48 per person, this tour offers a decent value considering the included stops, boat ride, and transportation. The price doesn’t cover the €5 volcanic entry fee, which is an extra cost. When you add this in, the total becomes closer to $65, still reasonable for a full-day adventure that covers so much ground.

Group Size & Atmosphere

With a capacity of up to 250 travelers, the boat can feel quite bustling, especially during peak season. The reviews suggest that despite the size, the guides do a good job of making the experience engaging and informative, which helps mitigate the crowding.

What’s Included & Not

The tour includes air-conditioned transportation from your hotel (or nearby pickup), and the boat ride itself. You should prepare for the additional volcanic entry fee and bring cash or a card for that. Children under 4 can join for free but won’t have a reserved seat, so if you’re traveling with little ones, plan for space on your lap.

COVID-19 Measures

Safety protocols are in place, including mask-wearing, frequent cleaning, and social distancing, which should help you feel comfortable during your excursion.

Authentic Traveler Insights

From reviews, we learn that many travelers appreciated the guides’ knowledge and clarity, making complex volcanic stories accessible. The views of Santorini from the water are consistently praised; many mention the stunning scenery as a highlight. One traveler shared that they enjoyed walking around Thirasia and swimming in the hot springs, noting that the warm water was quite pleasant.

Some found the boat a little crowded, but others didn’t mind, citing the large size of the vessel and the chance to walk around and take photos. One guest appreciated the complementary transportation from their hotel, which was a thoughtful touch.

While not all reviews are glowing, most agree that the experience offers a good mix of adventure and relaxation. The value for money is generally considered fair, especially given the variety of stops and scenery.

Who Should Consider This Tour?

This cruise is ideal for active travelers who want to see the volcanic islands and hot springs without too much hassle. It works well if you enjoy boat rides, scenic views, and light physical activity like walking up volcano paths or swimming.

It’s suitable for those looking for a full-day experience that combines education, adventure, and relaxation—though groups may be large, so if you’re sensitive to crowds, keep that in mind. Families with kids over the age of 4 could enjoy this, but younger children might find the boat and walking involved less comfortable.

If you’re someone who appreciates good guides and beautiful views, and you’re okay with a larger tour group, this trip could be a memorable part of your Santorini holiday.
