Santorini: Thirassia Islands and Volcano Guided Cruise

Exploring Santorini’s Volcano and Thirassia Island on a Guided Cruise

This guided cruise offers a well-rounded glimpse into Santorini’s volcanic and island scenery, taking you from the active Nea Kameni volcano to the tranquil beaches of Thirassia. For about $58, you get a full day of natural wonders, cultural sights, and scenic water views, making it a surprisingly affordable way to see some of the island’s most compelling features.

What I really like about this experience is how it balances adventure with relaxation. You’ll enjoy the thrill of walking up an active volcano, a chance to swim in the colorful hot springs, and ample time to wander or lounge on Thirassia’s peaceful beaches. Plus, with a knowledgeable guide leading the way—some reviews mention guides like Christophe or Vaso—you’re guaranteed insightful commentary and local tips.

One consideration: the trip can be quite full, especially during peak season, and if you’re not comfortable with rocky hikes or the heat, you’ll want to come prepared. Also, the boat doesn’t always stop at Thirassia until late June, so the full island experience might be slightly limited at certain times. Still, for the price and the natural beauty packed into a single day, it remains a top choice for many travelers wanting a taste of Santorini’s volcanic side.

Discovering Santorini’s Volcanic Heart: The Itinerary Breakdown

When you sign up for this cruise, you’re signing up for a full day that combines natural spectacle with cultural touches. You’ll meet at Athinios Port, stepping aboard a comfortable boat that, despite sometimes being crowded, offers an enjoyable journey on the water.

Nea Kameni: The Active Volcano
The first stop is Nea Kameni, a tiny, uninhabited island formed from recent volcanic activity. Here, you’ll hike along a soil path, climbing toward the crater where you can see the still-active volcano up close. Many reviews highlight how memorable this part is—one reviewer called it “an incredible day” and appreciated the “interesting” hike, especially with a guide like Christophe who kept things engaging.

The walk is rocky and steep in places. Travelers should pack sturdy shoes—flip-flops won’t cut it—and be prepared for the sun, especially around midday. You’ll get about 30-45 minutes to explore the crater and learn about the volcanic forces that built Santorini. For those concerned about the hike, reviews suggest it’s manageable for most and worth the effort for the views and the sense of standing on an active volcano.

Palaia Kameni & Hot Springs
Next, the boat approaches within 50 meters of Palaia Kameni, the second lava island. Here, you get to take a dip in the naturally warm, sulfur-rich waters of the hot springs. Around 15-30 minutes are spent at this stop, giving you enough time to swim or simply enjoy the scenery. Many reviews mention how unique and relaxing this experience is, with some wishing for pool noodles or flotation devices—”a nice idea,” as one reviewer put it.

The hot springs are a vivid green due to the sulfur, creating a striking contrast with the black lava rocks. It’s a quick, refreshing escape, and the water temperature is just right for most visitors after the volcano hike. Keep in mind, the water can be sulfur-smelling, so don’t expect a pristine beach experience but rather a natural, invigorating soak.

Thirassia Island: Quiet Beauty and Cultural Charm
After the volcanic and geothermal experiences, the cruise heads to Thirassia, a lesser-visited island that offers a slower, more authentic vibe. With about two hours here, you can choose to relax on the beaches, explore the village of Manolas—famous for its colorful, traditional houses—or enjoy a seaside lunch.

Many reviews praise Thirassia as a peaceful retreat. One traveler loved wandering the village, noting the vibrant houses, and another enjoyed swimming in the calm waters. The island is largely untouched by mass tourism, which adds a special charm, and guides often share stories about local life. Note that until late June, the boat might not stop on Thirassia, and guests stay onboard with snacks available for purchase—a minor inconvenience, but still a peaceful way to enjoy the scenery.

A Scenic Return and Oia View
As the boat makes its way back toward Athinios, you’ll have a chance to see Oia from the water—an iconic view that’s worth capturing. The captain will navigate past the cliffs, giving you a fresh perspective on the famous village, often slightly less crowded than on land.

On arrival back at the port, a comfortable bus transports you to your hotel. The entire experience is well-paced, but remember, the group can be quite large, and the boat may be crowded during peak times.

This trip suits travelers who want a balanced mix of ease and adventure without breaking the bank. It’s ideal if you’re comfortable with some walking, rocky terrain, and a bit of sun exposure. If you’re traveling with family, most of the stops are suitable for older children, though the hike may be a challenge for very young or mobility-limited guests.

For those who love natural beauty, geological marvels, or simply want a scenic cruise with cultural touches, this experience offers a compelling blend. It’s perfect for visitors who appreciate guides who share stories, and those who enjoy a relaxed pace—especially on Thirassia’s tranquil beaches.
