Santorini: Volcanic Islands Cruise with Hot Springs Visit

Exploring Santorini’s volcanic landscape by boat is a memorable way to see a side of the island that’s both wild and stunning. This cruise, offered by NST Santorini Tours, takes you around the caldera, to an active volcano, hot springs, and the charming island of Thirassia, culminating in a famous sunset in Oia. It generally receives positive reviews for its scenery, knowledgeable guides, and affordability, making it a popular choice for travelers eager to combine adventure and relaxation.

What I especially like about this tour is how it balances multiple highlights—hiking a still-active volcano and soaking in warm sulfur springs—without feeling rushed. The boat crew receives high praise for their friendliness and expertise, making the experience smoother and more engaging. Plus, the chance to enjoy a scenic cruise with panoramic views of Santorini’s volcanic cliffs is hard to beat.

One potential downside to consider is that the hike on Nea Kameni (the active volcano) is unguided, so if you’re not comfortable with uneven terrain or hot surfaces, you’ll want to prepare accordingly. Also, during peak summer months, the boat can be crowded, which might impact your comfort, especially during hot springs or tight spaces. But overall, the experience offers excellent value at around $28 per person, considering all the stops and activities included.

Exploring Santorini’s Caldera from the Water

If you’re like me, one of the best ways to appreciate Santorini is from the water. This cruise starts from Athinios Port, with pick-up options that include a short bus ride from your hotel or nearby village. Once onboard a traditional wooden boat, you’ll immediately feel the charm of the Aegean. The boat is equipped with foam noodles for lounging, and the crew is friendly and informative, often sharing insights about the volcanoes and islands.

The live commentary enhances the experience, making the stops more meaningful. From the start, it’s clear that this tour is designed to balance sightseeing with comfort—you’re not rushed through the highlights but given enough time to soak in the views.

The Volcano: Active and Engaging

Nea Kameni is the star of the tour. It’s an island with a still-active volcano, and hiking to the crater is optional but highly recommended. Many reviews praise guides like Yiannis for their detailed explanations, and some mention that the hike is about 35 minutes one way. The terrain can be uneven, with volcanic sand and rough paths, so sturdy shoes are essential.

What makes this stop special is the chance to see the volcano’s still-smoking crater, a reminder of the island’s fiery origins. The walk is manageable for most, though some travelers note that it can be a bit windy and hot, so bringing water and wearing pants (to protect against sand) is wise. The view from the top is spectacular, with panoramic shots of the caldera and the volcanic island’s moonscape.

Soaking in the Hot Springs

After the volcano, the boat anchors at Palea Kameni for a swim in the sulfur springs. The waters are known for their mineral content and supposed healing properties. One thing to keep in mind is that the springs are more warm than hot, which some reviews find pleasantly soothing. The mineral-rich waters may stain lighter swimwear, which is a quirky detail worth knowing.

Getting into the springs involves some jumping or ladder-climbing, depending on your confidence. Non-swimmers can stay on the boat, which is equipped with life jackets. The stop is limited to 30 minutes due to port regulations, so plan your swim accordingly. Many reviewers say swimming here is the highlight, and some note how refreshing it feels after the volcanic hike.

Thirassia: A Quiet Retreat

The cruise usually includes a second swim stop at Thirassia, a small, traditional island that offers a peaceful atmosphere away from the crowds. The bay provides calm waters for another dip, and many find this addition a lovely way to unwind. If weather conditions are good, you’ll have around 30 minutes here—enough to dip your toes in the sea or simply enjoy the view.

Some reviews mention that the Thirassia stop is well worth it. It’s less touristy than Santorini proper, with a slower pace and authentic village charm. If you’re up for a hike, some guides suggest a walk up to enjoy panoramic views, but most people simply relax and soak in the quiet.

Scenic Caldera Cruise and Villages

The second half of the trip is a leisurely sail past the island’s famous whitewashed villages, perched dramatically above the sea. The cliffs’ towering presence and the colorful buildings make for stunning photos. It’s the kind of scenery that makes you understand why Santorini is so beloved.

The cruise ends back at Athinios Port around 15:45, giving you plenty of time afterward to continue exploring or relax in your hotel. For those who book the extension, a bus will take you to Oia, where you’ll spend 2-3 hours wandering its charming streets and watching the sunset.

The Oia Sunset Extension: A Magical Finish

Oia’s sunset is often called the most famous in Greece, and for good reason. The extension option allows you to visit this picture-perfect village after the cruise, with ample time to explore its narrow lanes, visit local shops, and find a prime spot for the sunset. The meeting point in Oia is set 15 minutes after sunset, making it easy to coordinate with your guide.

Many reviews highlight the sunset as a must-see, and the extra time here is well worth it. Just remember that Oia is touristy, so expect crowds and be prepared for a lively, vibrant atmosphere rather than quiet serenity.

Final Thoughts: Who Would Love This?

This tour offers a fantastic mix of adventure, relaxation, and incredible scenery—all for a reasonable price. It’s especially suited for travelers who want to see the volcanic activity up close, enjoy a refreshing swim, and experience a classic Santorini sunset without spending a fortune. The knowledgeable guides, particularly Yiannis, help bring the landscape to life, making each stop interesting and enjoyable.

This experience works well for active travelers comfortable with some walking and swimming, but those seeking a leisurely, less crowded day will find the small group size and scenic stops appealing. Families with older children, couples, and solo travelers alike will appreciate the balance of sights and downtime.

However, keep in mind that the hike is unguided, so bring sturdy shoes and water. Also, during the busy months, the boat can be crowded. If you prioritize comfort, arriving early and bringing your own snacks might improve your day.

This tour offers a budget-friendly, well-rounded way to experience Santorini’s volcanic origins and breathtaking scenery. Whether you’re a first-timer or returning for another look, it’s a memorable snapshot of what makes this island so special.
