About this experience
Your journey begins based on your selection: with pickup from Athinios Port, or without pickup from the Old Port of Fira. The first stop is the volcano, where you’ll have 1.5 hours to hike its rugged trails and explore its unique landscape. A 5€ entrance fee is required to access the volcano. Your tour escort will guide you along the paths, sharing fascinating stories about its history and eruptions. Wear sturdy shoes and bring water for this moderate hike, which rewards you with stunning panoramic views at the summit. Next, sail to the hot springs at Palea Kameni. The boat will anchor 30-50 meters from the springs, requiring a swim to reach the warm, sulfur-rich waters. This activity is recommended only for strong swimmers due to the distance. The final stop is Thirassia, where you can explore its charming villages, take in breathtaking views, or savor a delicious meal at a traditional taverna before returning to your starting port.

Daily Cruise in Santorini
Not to miss while in Santorini. Great value for money. Perfectly organized. Multilingual tour guide. Would do it again.

Nice views and good food but nothing special
Was a nuisance to get to from our hostel, super hot (recommend going during spring or fall), and wasn’t super pleased with the volcano hike or thermal pool. Disclaimer: thermal pool doesn’t mean warm (it’s due to the vitamin and mineral concentration of the water). The views were nice from the volcano and the boat when going to and from the start point. The island you stop at for lunch is very small and mostly filled with shops and places to eat. Overall, was ok but nothing super special

A very nice cruise
It was an amazing experience! I will suggest 15 more minutes at volcano! Or to be more strict at departure time!

Amazing boat tour experience in Santorini Caldera
We really enjoyed the Caldera tour, visiting the Nea Kameni volcano, hotsprings and Thirassia island. The views were amazing and the guide provided interesting information on the Santorini island complex, history of the volcanic erruptions and formation of the Caldera, and the different regions/towns of the main Fira island. Climbing the volcano was worth the beautiful panoramic views of the whole of Santorini - would definitely recommend suitable footwear for this. The climb wasn't too intensive but you will need a basic level of fitness. The hotsprings were fun for a refreshing dip in the sea, but as advised the sulfur waters can stain your costume (mine was purple and still stained) - definitely avoid white/light coloured costumes. They were comparatively warmer than the rest of the sea, but not as hot as the name "hotsprings" may suggest. Still a very cool experience. The stop in Thirassia was cut short to 1hr 20mins for some reason, but we still enjoyed the visit to the pretty port of the island, with restaurants, cafes, and a pebbly beach where you can swim or sunbathe. I will say that a lot of the food options there are quite overpriced/tourist trap vibes, as is typical for Santorini, so do your research if you want to find a more budget option. The boat felt safe and was great for enjoying the sun & views of Santorini. Although other reviews have sometimes reported overcrowding, this was not our experience despite visiting in mid August. Overall would definitely recommend, a great way to get to know the island in 1 day!

Cruise from Santorini
Very well organized. Visitors need to be in a decent state of health for an uphill climb to watch the effects of the volcanoes which is one part of the trip.

Why this scores 78
The Outty Ranking is a weighted composite. Here is how this experience performed on each component.
Santorini Caldera Cruise Tour (Volcano, Hot Springs, Thirassia): questions travelers ask
Practical detail on this experience, plus the wider planning questions for Santorini.
How much does Santorini Caldera Cruise Tour (Volcano, Hot Springs, Thirassia) cost?
+
Prices start at $18 per person. The final price depends on the date, the time slot and the number of travelers, and peak weekends in Santorini usually price higher than midweek mornings. Live pricing and remaining availability are confirmed on the booking screen before you pay.
How long does Santorini Caldera Cruise Tour (Volcano, Hot Springs, Thirassia) take?
+
Plan for about 6 hours from start to finish, not counting travel to the meeting point. Most travelers leave another 30 minutes on either side so the rest of the day in Santorini is not rushed.
Is Santorini Caldera Cruise Tour (Volcano, Hot Springs, Thirassia) worth it?
+
It holds an Outty Ranking of 78 out of 100, which we label "Strongly Recommended". That score blends traveler sentiment (4.4/5 across 1,411 reviews), the depth of that review evidence, recent booking momentum, value for money against comparable most popular in Santorini, and how flexible the cancellation terms are.
Can I cancel or reschedule Santorini Caldera Cruise Tour (Volcano, Hot Springs, Thirassia)?
+
Yes. Cancel free up to 24 hours before the start time for a full refund. Inside that window the booking is non-refundable, and no-shows are not refunded.
Is Santorini Caldera Cruise Tour (Volcano, Hot Springs, Thirassia) suitable for kids and families?
+
Yes, all ages are welcome. Families should still weigh the 6-hour running time, and strollers are easier on the earlier, quieter departures.
How far in advance should I book Santorini Caldera Cruise Tour (Volcano, Hot Springs, Thirassia)?
+
Around 494 people booked this in the last 30 days, so popular slots go early. Two to three weeks ahead is comfortable in shoulder season, while summer weekends and holidays in Santorini can sell out a month out. Same-day spots do open up when other travelers cancel, so it is worth checking if you are already in town.
What should I bring or wear?
+
Bring photo ID, your booking confirmation on your phone, a refillable water bottle and comfortable shoes. Dress for the weather in Santorini and add a light layer if any part of the 6-hour experience runs outdoors or after sunset.
Where does Santorini Caldera Cruise Tour (Volcano, Hot Springs, Thirassia) start and how do I get there?
+
The exact meeting point and directions are on your voucher once you book, and they sit in central Santorini within reach of public transport. Arrive 15 minutes early: late arrivals are treated as no-shows by most operators.
What are the best things to do in Santorini?
+
On Outty we rank every Santorini experience on the same 0 to 100 scale, and alongside this one the highest scorers right now include Half Day Premium Catamaran Cruise in Santorini including Oia, Private Santorini Tailor Made - Choice of the Guest!, Private Classic Santorini Panorama: Visit Top Destinations. The city page groups everything into most popular, highest reviewed, last minute and family-friendly so you can build a day around what actually delivers.
When is the best time to visit Santorini?
+
Booking patterns follow the same curve: prices and queues climb in peak weeks, while shoulder season gives you better availability on the top-ranked experiences and more room to change plans.
How many days do you need in Santorini?
+
Three full days covers the headline sights without sprinting. A workable rhythm is one anchor experience each morning, such as this one, an unhurried afternoon in a single neighborhood, then a food or nightlife booking in the evening. Five days lets you add a day trip outside the city.
Do I book through Outty or through the operator?
+
Outty ranks and explains the experiences, then hands you to Viator to complete the booking with the operator directly. The price is the same as booking on Viator yourself, and Outty earns an affiliate commission on the referral, which is how the rankings stay free to read.
