Santorini Volcano and Hot Springs Boat Tour

The tour departs daily from the old port of Fira, at 11:00 in the morning or at 14:00. After only 15 minutes by boat, we'll be arriving at the volcano bay, where we'll be docking for about 1 hour and 30 minutes, during which, if you want, you can follow the path to the top where active craters are. Next we'll be moving to the island of Palea Kameni for the hot springs, the famous mud baths, which were formed as result of volcanic eruptions. In the small bay of Agios Nikolaos the water temperature ranges from 30 to 35 degrees Celsius, as it mixes continuously with the normal sea currents. The boat will be staying here about 30 minutes to allow you a healthy bath. After the bath, you will return to the old port of Fira.


The excursion starts from the picturesque old port of Santorini. This port is only accessible by cable car which is the most common way as it takes only 3 minutes to go down, 587 steps on foot or for those who love the adventure, the local donkeys is the ideal choice to reach it. Important note : You should pay 6€ more per way either for the cable car ticket or to ride one of the donkeys. Gialos, the Old Port, lies below Fira, nestled at the foot of a rocky cliff. You will be surprised with the steep slopes of the Caldera and in the end the tiny port will appear under these huge rocks and the cave houses that seem to dangle on the cliff. There the guides of your excursion will be waiting for you, to give you all the important information and to orientate you on the boat. For more information or clarifications, don’t hesitate to visit our travel agency which is located down at the port.


Our first destination will be the famous volcano of Santorini! After 20 minutes sailing, we will reach Nea Kameni’s jetty. Should you are interested to be guided at the volcano, you should pay 2.5euro/ per person as an entrance fee. Then, you will walk to the volcano’s ridge with your guide and he is going to explain you everything about the history and the geology of the volcano. You will stay at the volcanic island for 1.5hr and in the end you will embark again to our boat for the next stop.

Hot Springs

Our next stop will be the island of Palea Kameni where the famous hot springs are located on the west side. A place that is really popular for its thermal waters. We will stop there for 30min at a distance of 30 meters from the shallow waters of Agios Nicholaos’ beach. The waters are mixed with mud that they are full of sulfur, iron and other metals coming from the volcano and they are very good for the skin, rheumatism, arthritis and other physical pains. Important Note : In order to reach Agios Nicholaos’ beach is essential to swim extremely well.


After departing from your last destination, the tour will be finished at the old port of Fira. After your disembarkation, you should choose one of the available ways to go back to Fira town. Please note that you will have to pay again the additional cost for your transport back to Fira town.

Ideal ride to volcano

A great experience! We went mid-November. Weather was great and the boat was wooden, not too crowded and attractive. Great view of caldera and then volcano. Given enough time to casually follow the path from the top of the volcano and back. They put fun music on as we went around the corner to where some people got out and swam, then took boat back around last part of volcano to Fira port. You can buy a drink and crisps on board, and there is a small top deck next to the driver too. Great value, just what we wanted.

Something to do

Okay for value. Went on a boat, water for 5 min (noodles offered), and walked the volcano. The port was nice. Nothing to write home about but something to do.

Santorini Volcano & Hot Springs Boat Tour

This was a good experience... Fun to travel on one of the wooden Greek vessels... If the wind is up it can get a little dicey but you feel like it's an adventure... This is a trip for those who don't want to spend all day (it is only about 2 - 2 1/2 hours)... You do get off the boat twice (once at the volcano and also at the hot springs)... The second stop allows for those who want to jump in the water and swim over to the shallows where the warm water from the springs is located... Enjoyed the tour

A great experience!, A must do.

Great value tour on a lovely boat

This was a superb tour (way cheaper than the same tour from our cruise ship) with a well maintained boat, helpful guide and decent sized group. The tour gets you to the top of the Nearest Kameni volcano, then allows you to swim in the springs off Paleo Kameni (the old, dormant stack of the volcano). Definitely recommended, would do again when we are on Santorini. , Well organized!

Breathtaking and worth it!!

Must take experience...different and worth it but very salty 😝 experience...we are good we took it. Our guide was awesome and trip was very Well organized!

Recommended with both hands!

Fantastic! Just fantastic! Especially the swimming to hot springs. To new travellers - if you are not so good in swimming, they will give you a swimming stick - with it you can not drown. You can jump to water right from the ship or you can walk down a staircase. There's WC on the ship, where you can change wet swimming suit. Nea-Kameni. There you have to pay ecological fee to go and see the caldera and the island. Given time is enough for a good walk and taking photos. The trip is very safe. Everyone left their belongings while swimming. Nothing happened to them. And one more thing. You have to get down from Tira to the Old port to catch the ship. You can walk 300 steps down, but this is very difficult, because the road is cobbled. If you walk, don't take suit-cases with you! Backpack is OK. You can also ride a donkey for 5 euro, but pay attention, that donkeys go slowly! Probably 40 min to the port. Just like on your feet. The best choice for tired travellers with luggage is cable car. It costs 6 euro, and in 5 min you are down in the port! That's it. Have a good trip! A great experience!

Great little adventure

Enjoyed the 3 hour volcano trip along with the hot spring tour. The tour was fun and insightful, the volcano trek can be daunting but it is worth the views and the dip in the hot spring was definitely worth it. , A great experience!

GREAT trip!!

A great trip, the volcano was amazing and enough time to explore! The hot springs i would say that even if you aren't a strong swimmer it isn't far until it is shallow and they offer you a foam finger to help - my partner didn't want to go in due to it saying you needed to be a good swimmer. Definitely a MUST DO on your holiday! , A great experience!, Excellent!, Well organized!, Wonderful experience!, A must do., Our guide was awesome!

Very good tour

We turned the schedule around because there were too many boats on the volcano. So we went first to swim in hot springs and it was really a great time. We jumped from the boat into the sea and swimmed 10 minutes to the springs. You can walk there because it is low water and then we swimmed back to the ship. There was enough time. Then we went to the volcano, you pay extra 2.5€ per person there and then you walk 20 minutes up to the top. You can feel the heat comming out from the ground. You walk around there a little and then go by ship again back to the port., Well organized!

Nice excursion on a beautiful boat

I was almost 40 (!) years ago on New Kameni and was very impressed by the "moon"look of the small island and saw more fumes/vapor coming out of the ground. Of course, we had more time to explore, since we were just a few tourists at the time. In July 2018, times have changed, the tourist crowd is everywhere! The swim in the Hot Springs was very nice, though...
