What You Can Expect

Santorini Volcano Cruise Including Hot Springs, Thirasia and Optional Oia Sunset

Upgrade to experience the unforgettable Oia sunset!

After pickup from your Santorini hotel, travel to the portside at Athinios and board your comfortable sightseeing boat for your 7-hour cruise.

Find a spot on deck, settle in an enjoy the views over Santorini’s towering cliffs as you sail across the waters of the caldera to the volcanic island of Nea Kameni. This small, barren islet is a National Park and boasts a landscape formed from rugged lava and ash with a volcanic crater at its heart.

Step ashore, pay your entrance fee to the park, and enjoy roughly 1.5 hours of free time to explore the moon-like landscape. Perhaps follow the trails around the crater rim and capture the spectacular views back across to Santorini, with its shimmering white towns clinging to the cliffs.

After exploring, cruise to a small coastal bay fed by naturally heated, underwater springs. Take a dip into the invitingly warm waters that are believed to have therapeutic benefits, and perhaps rub some of the revitalizing iron-rich mud into your skin.

Duly refreshed, sail on to Thirasia, a large island basking just off Santorini’s northwest coast. Separated from Santorini by a 236 BC eruption, most of the island’s small community live in its main, clifftop village.

Go ashore and enjoy ample free time to stroll around the pretty streets and relax independently. If you’re peckish, perhaps ask your guide for restaurant recommendations and have lunch (own expense) at a taverna or café.

In the late afternoon, cruise back to Athinios port on Santorini and finish your tour with a hotel drop-off.

Cruise with Oia Sunset Visit Upgrade:
Make the most of your cruise by upgrading to include a visit to the sunset village of Oia. Hop off your boat near Oia during the return cruise to Athinios, and walk up to Oia village to witness one of its famously beautiful sunsets.

Head for the cliff-edge terraces and snap photos as the sun sinks below the horizon, casting the caldera in a stunning, red-and-orange glow — it’s an unmissable sight!

After sundown, your tour then finishes with a drop-off at your island hotel.

The only thing I would like to say is do not book this tour with viator. Wait until you are in Santorini, the prices are almost triple online than purchasing in person. Great tour and worth the money, but not 60.00 per person. We spoke with other people on the tour and they spent around 20.00 per person for the same trip.

The trip was highly organized. Our tour guide was the absolute best!! He was very knowledgable abut the geology of the volcano. Wish the hot springs were really hot a little false advertising there! Otherwise, it was a perfect day!

The tour itself was great. The guide was excellent!

However they state "hotel pickup" which did not happen. They called the day before to say to meet at a point in the city (Fira) that was about 1km walk from the hotel.

Wear comfortable shoes for the climb up the mountain and up Oia cliff as well

Very friendly and knowledgeable english speaking guide. Had an enjoyable day trip on the boat. Great views on the volcanic island but plenty of climbing and walking to do.
