What you'll see and do
Santorini Volcano
The tour starts at 09:20 from our office with a bus. It takes you to the port of Athinios, you will board the boat and start our trip with destination the Volcano, a distance of about 15-20 minutes. Your stay there is for about 1 hour and 15 minutes. To walk up to the volcano to meet the active craters is about 20 minutes through a walkable path. It is worth reaching the top because when you arrive there, if you scratch the surface you will see steam coming out, smell the sulfur and also to take pictures.

Palea Kameni
After the visit of Nea Kameni, the boat continues to the island of Palaia Kameni where the Hot Springs are located. The boat anchors a few meters outside the small bay of Agios Nikolaos, it lowers down a ladder in the water and from there you can swim a distance of about 20 meters to get to the famous mud baths of Palaia Kameni for which are believed to have beneficial abilities for the skin and other diseases. The water temperature is 30-35 degrees but it constantly mixes with seawater. The boat remains here for about 30 minutes for swimming. It's quite a time since there is no beach on the small island where you can stay for a while.

Thirassia
In continuation of the tour, the boat sails to the island of Thirassia. You have 2 hours free time to swim in the crystal waters of Korfos or eating in traditional taverns with different dishes of the island. You can go on foot or by donkeys in the village of Manolas, which is very picturesque with narrow streets and nice view to Santorini and worth a visit. After the 2 hour pleasant break on the island of Thirassia, we start to return back to the port sailing near the volcanic cliffs of Oia to take pictures of the unique landscape.

Full packed bus
The saling and trip was very Nice. But the transfer with bus was awful. I hat to sit with my teen year old on my lap. Because of over booked bus. And no places to sit.

To be avoided
Booked in Oia. Departed at 8.50 arriving at the ferry port at 9.30. Too much time waiting for tourist buses from all over the island. Stop at the old port of Fira until 11. An endless waste of time. Minimum explanations of the volcano and hot springs. In the afternoon between Thirasia and Oia the commander tried to cut the way to a huge ferry with the result of having to block the engines suddenly and be hit by the waves of the wake with abnormal pitch.

Sardines on a school trip.
Really a disappointment. It all started with a messy pick-up at the hotel, bad driver to the port, hours of unnecessary waiting without info and then: packed boat and a grumpy guide who only: ‘Follow me pliiiiiisss’ could say. We were treated like preschoolers. The boat is not comfortable and also not very big. The destinations we visit are also not very spectacular. The volcano is most beautiful from the water, the hot spring is with brown water and too full, and Thirasia is still going, except that it is also busy there, and MUST stay on the quay for two hours, I asked if we could get back on board, just to sit, but 3:10 !! there was shouting from the upper deck. Then there are 100+ people waiting in the sun and that pet only opens the gate to board at 3:20. To top it all off, at 4pm there is a coach waiting to take us to Oia like stinking sardines, once there, own transport arranged back... what chaos!

Need to better inform customers
Contrary to what we were told, there was no French guide. We waited 30 minutes on the port before leaving because the boat was not ready. On the return trip, it is impossible to dock at the port of departure, the sea being too strong, so direction Fira. Now we're being asked to pay for the funicular to get back into town to find our bus... which wasn't there. We are put in a taxi, which asks us to pay once we arrive at the hotel, when we had paid the transfer! Not very serious. The volcanic island is worth a visit.

Do this tour!
I really enjoyed this tour! Climb the volcano on Nea Kemini, swim to the hot springs on Palea Kemini (if you're a strong swimmer - 2 people from our group had to be rescued - but it is fun enough just staying on the boat and taking photos of the volcanic rocks, pigs and goats, and the other boats), pick a place for lunch in the port at Thirasia, and climb the steps to the top if you want to (beautiful views). On the way back the boat stops for a bit to give you a chance to look through the glass bottom (not much to see but rocks and a very few tiny fish on my trip but the color of the water is beautiful), and then sail past Oia to view it from the sea. The tour guide goes up the volcano with the group and provides lots of info as well as giving some info about each of the other stops while on the boat (in English, French and Italian). Other than that, you have free time to explore on your own. A very fun day.

Why this scores 48
The Outty Ranking is a weighted composite. Here is how this experience performed on each component.
Santorini Tour of Caldera & Sunset In Oia with Glass-bottom Boat: questions travelers ask
Practical detail on this experience, plus the wider planning questions for Santorini.
How much does Santorini Tour of Caldera & Sunset In Oia with Glass-bottom Boat cost?
+
Prices start at $65 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 Tour of Caldera & Sunset In Oia with Glass-bottom Boat take?
+
Plan for about 9 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 Tour of Caldera & Sunset In Oia with Glass-bottom Boat worth it?
+
It holds an Outty Ranking of 48 out of 100, which we label "Worth a Look". That score blends traveler sentiment (3.1/5 across 15 reviews), the depth of that review evidence, recent booking momentum, value for money against comparable last minute in Santorini, and how flexible the cancellation terms are.
Can I cancel or reschedule Santorini Tour of Caldera & Sunset In Oia with Glass-bottom Boat?
+
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 Tour of Caldera & Sunset In Oia with Glass-bottom Boat suitable for kids and families?
+
Yes, all ages are welcome. Families should still weigh the 9-hour running time, and strollers are easier on the earlier, quieter departures.
How far in advance should I book Santorini Tour of Caldera & Sunset In Oia with Glass-bottom Boat?
+
Around 5 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 9-hour experience runs outdoors or after sunset.
Where does Santorini Tour of Caldera & Sunset In Oia with Glass-bottom Boat 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.
