The tour’s highlight is the visit to Nea Kameni, where you walk up a soil path to approach the crater of this still-active volcano. The walk is manageable for most visitors with moderate fitness levels. Afterward, the boat moves to Palea Kameni, where you can dive into the hot springs located about 50 meters from the sulfur-rich waters. The greenish hue of the springs makes for memorable photos, and relaxing in these natural thermal waters is a calming experience.
The hot springs stop is brief but well-organized, with enough time to enjoy the warm waters or simply take in the views. The volcano entrance fee of 5 Euros is paid separately, so budget accordingly.

After the volcanic visits, the boat sails to Thirasia Island, a quieter spot compared to Santorini’s tourist hotspots. You stay here for 2-3 hours, making it an ideal chance to swim in the sea, explore the village of Manolas, or grab lunch at local tavernas. The village’s winding streets and traditional houses offer a glimpse of authentic island life, away from the larger crowds.
The swimming opportunities are ideal for those comfortable with water activities, and the village walk provides a pleasant break from the boat trip. Many find the time on Thirasia to be one of the most relaxing moments of the tour.

The final leg of the tour takes the bus from Athinios back to Oia, renowned for its spectacular sunset scenery. The 30-minute drive allows plenty of time to settle into a good vantage point. The sunset in Oia is famous for its vivid colors and picturesque setting, making it a highlight for many travelers.
The tour concludes about 30 minutes after sunset, allowing visitors to linger in the village or head back at their leisure. The bus then waits at the designated pickup point to return you to your original meeting area.
