Excursion details

The great six-hour sea tour is a boat trip along the Santorini caldera. On this trip you will go to the area of the islands of Nea Kameni and Palea Kameni, as well as the island of Thirasia (also known as Thirassia or Therasia). During the excellent half-day trip you can look at island from the water, walk along the dormant volcano, swim in the hot springs and visit the Thirasia.

You will see the following key sights on this trip:

  • Caldera of Santorini;
  • Nea Kameni island;
  • Palea Kameni island and Hot springs;
  • Thirasia island.

The boat trip departs from the picturesque Old Port of Santorini, which is located at the foot of a rocky cliff in Fira (Thira). A cable car leads to it, as well as a staircase of 587 steps; the option of descent and ascent is your choice. The descent on the funicular takes only 3 minutes, but walking will take much longer. However, you can ride down on the back of a donkey 😉

A boat will be waiting for you at the harbour, and once out to sea, it will take you to the famous volcano of Santorini. The boat will approach the pier of the island of Nea Kameni in 15 minutes. You can stay on the ship and look at Nea Kameni from its deck or join a walk through the territory of the volcano – about an hour and a half is planned for it.

The next stop of the boat trip will be the island of Palea Kameni, the famous thermal springs are located next to the island. At this point there will be a stop for half an hour and the ship will come as close as possible to the small bay and rocky beach of Agios Nikolaos, where you can swim in the hot springs. The water color is very unusual here because the hot springs are full of sulfur, iron and other metals rising to the surface from the bowels of the earth. If you are going to swim, take swimsuits in dark colors!

The next point on the route is the island of Thirasia, which offers a picturesque view of Santorini. In a sense, this is its miniature copy in the recent past: the island has still remained aloof from mass tourism, huge popularity and modern life. Only about three hundred people live on the area of ​​about nine square kilometers! It takes about two hours to visit Thirasia, where you can not only walk or swim, but also have lunch in one of the taverns of your choise.

The ship will then make its way to the old port of Fira.
