What to Expect from the Santorini Volcano & Sunset Tour

This tour is a well-rounded package that combines natural wonders, local culture, and breathtaking vistas. It begins early with a hotel pickup, making it convenient and stress-free. From there, you’ll head to the port of Athinios, the gateway to this scenic adventure.

Starting with the Volcano: Nea Kameni

Once aboard your boat, the first highlight is the volcanic island of Nea Kameni. Here, you’ll climb a bumpy trail to reach the crater of an active volcano. While the walk involves some effort and uneven terrain, the views of the caldera and the volcanic landscape are worth every step. Travel reviews mention that guides like Christos make the hike both informative and engaging, sharing insights into the island’s geology and history. Be prepared for dusty paths and wear sturdy shoes.

Once at the top, you’ll get a clear sense of the volcano’s power—fumaroles, volcanic rocks, and the sense of standing on a bubbling, fiery core. This active site provides an unforgettable experience and a fantastic photo opportunity.

Continuing to Palea Kameni and the Hot Springs

After descending from Nea Kameni, the boat moves to Palea Kameni. Here, you’ll find the thermal springs—a highlight for many travelers. The boat approaches within 50 meters of the springs, allowing you to swim or relax in the green sulfurous waters. Reviewers have noted that the experience of floating in these mineral-rich waters is both relaxing and slightly bizarre, thanks to the sulfur smell and the vivid green hue.

Keep in mind that the entry fee for the volcano (around 5 euros, payable in cash on site) isn’t included in the tour price. Also, some guests mentioned that the springs can be quite crowded, but the natural setting and the chance to experience volcanic water make it worthwhile.

Exploring Thirasia

Next stop is Thirasia, a lesser-known gem that was once part of Santorini before a major volcanic eruption separated it. This island has a quaint old village called Manola with spiral staircases and traditional houses—a perfect spot for wandering, snapping photos, and soaking in authentic local life.

Guests often spend time swimming, enjoying a snack, or exploring the village’s narrow streets. The beach on Thirasia is rocky, so bring appropriate footwear if you plan to swim or walk along the shore. Some reviews mention that due to COVID-19 adjustments, the tour might not stop at Thirasia until later in the season, with some guests remaining on board and enjoying snack options instead.

The Return Journey & Oia Sunset

As the boat heads back toward Santorini, it glides under the cliffs of Oia, giving travelers a chance to admire the stunning caldera views from the sea. The final part of the tour involves a bus transfer to Oia, where you’ll have time to enjoy the world-famous sunset.

Oia’s sunset is often described as magical, with the sky turning vibrant shades of orange and pink. The tour ends roughly 30 minutes after sunset, and from there, you can explore the charming streets, browse local shops, or simply sit quietly and take in the scene.

Transportation & Logistics

Transport is seamless, with hotel pickup included from various locations like Fira, Imerovigli, Kamari, Ia, and Perissa. The tour is operated in English, with a live guide sharing interesting facts and answering questions along the way.

Keep in mind that the duration is about 9 hours, and the actual trip can extend a bit longer depending on the day’s schedule or tour updates. Guests have appreciated the punctuality and professionalism of the crew, especially the guides like Christos, who are often praised for their knowledge, humor, and friendly attitude.

What’s Included & What to Consider

Included in your ticket are roundtrip hotel transfers and a tour guide on the boat. However, some extras are on you: entry fees for the volcano (~$5 cash) and any lunch or snacks on Thirasia aren’t included. Guests are encouraged to bring comfortable shoes, swimwear, towels, and a light jacket—since the weather can vary and some parts involve walking on uneven ground.

A notable point from reviews is that during late June, the boat may not stop at Thirasia; instead, guests remain onboard with snacks for purchase. This change highlights how schedules can fluctuate slightly but hopefully will resume normal routes soon.

Authentic Experiences & Unique Insights

What makes this tour stand out are the guides like Christos and Tanja—reviewers repeatedly mention their wealth of knowledge, good humor, and attentiveness. Their commentary enhances the experience, helping you understand volcanic activity, island history, and cultural quirks.

Many guests appreciated the notable views of the caldera and Oia from the boat, which are often missed when only visiting on land. The opportunity to see the island from the water offers a different appreciation of Santorini’s volcanic origin and stunning cliffs.
