arriving at athinios port we board the traditional boat king thiras. Our first stop in the volcanic island of nea kameni where we walk an ascending soil path to approach the crater of still active volcano. We continue to the island of palea kameni where we can swim in the green sulphur waters or bath in the warm therapeutic mud. After half an hour, the boat will sail to the nice traditional island thirassia, where you can have lunch at one of the picturesque seafront tavernas or swim at the beach next to the port. The boat tour ends up at the village of oia where we will stay and admire the spectacular colourful sunset.
