Board a sightseeing boat at the old port and admire Santorini’s cliffs as you cruise to Nea Kammeni. Enjoy free time to walk around its volcanic crater, swim in the warm springs and visit Therasia island. Explore and have lunch there at leisure before cruising back to Santorini. Then explore Oia village and experience a unique sunset!

Departure

The excursion starts from the main port of Santorini, Athinios. The bus will pick you up from the nearest pick up point close to your location. Next, you will head to Athinios port where one of our guides will guide you in one of our boats. The tour starts at 10:15 in the morning.

Volcano

Our first destination will be the famous volcano of Santorini! After sailing for 20 minutes, we will reach Nea Kammeni’s jetty. Should you be interested to be guided at the volcano, you have to pay 5 euro per person as an entrance fee. Then, you will walk to the volcano’s ridge with your guide who is going to explain to you everything about the history and the geology of the volcano. You will stay at the volcanic island for 1.5 hour and after that you will embark again for the next stop.

Hot Springs

Our next stop will be the island of Palaia Kammeni, 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 30 minutes, at a distance of 30 meters from the shallow waters of Agios Nicholaos Beach. The waters 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, it is essential to swim extremely well.

Therasia

Next stop is the island of Therasia. Therasia is a miniature of what Santorini used to be several years ago. Today it is a virgin island, still untouched by tourism and modern life style. The island of Therasia is only 9 sq. km in size and has approximately 300 permanent inhabitants. We will stay there for 2 hours, so as to explore this picturesque and traditional village as well as to taste the authentic Santorinian cuisine. Should you wish so, you can also walk around the main village of Manolas, which is the capital of Therasia. The view of Santorini is spectacular from there.

Sunset in Oia off board

After Therasia island, you will go back to Athinios port where our bus will take you to Oia, the most beautiful village of Santorini. There you will have the chance to explore unique alleys, discover its rich market as well as enjoy fantastic views and the most breathtaking sunset of your life! After the sunset, you should head for the spot that our buses will be waiting to take you back to your places.

Good fun for such money! Well performed! Some advices: you need at last closed shoes for volcano and the walk is not just walk in the park. But the place is amazing! And swimming in hot spring happens after 30m swim in pretty deep and maybe not flat sea. So be prepared! Many thaks for tour operaator!!!, A great experience!, Well organized!
