The bus will take you to the port of Athinios, you will board the boat and start our trip with destination the Volcano, a distance of about 10 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. 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.
In continuation of the tour, the boat sails to the island of Thirassia. You have to swim in the crystal waters of bay Korfos, which is very picturesque with nice view to Santorini. After the pleasant break on the island of Thirassia, we start to return back to the port sailing near the volcanic cliffs of Oia with white houses and blue doms to take pictures of the unique landscape.
When we arrive in the port of Athinios there will be our bus waiting for you to get you to the village of Oia where you will have free time to walk through the narrow streets, take pictures of the mesmerising scenery and watch the famous sunset.
Right after the sunset our bus will be waiting for you to return you back to the starting point, where it also ends.
