Book on Viator Confirmed right away, but you pay full price.€800This private boat rental with Alex lasts five hours and begins at Santorini Old Harbor, located beneath the capital, Fira. The harbor was the island’s main entry point until 1960 and is accessible by steep steps or cable car. The boat first heads toward the volcanic area of Santorini. Guests can choose to stop at Nea Kameni Volcanic Park for about thirty minutes to explore the site of the most recent volcanic eruptions. If guests do not stop, the skipper provides a detailed explanation of the volcano that formed the Caldera. The first swimming stop is at the thermal springs near Nea Kameni, where volcanic activity warms the seawater to about 100 degrees Fahrenheit in some areas. These mineral-rich waters are believed to have skin benefits. After swimming, the boat moves to Palea Kameni, the first lava island formed in the center of the Caldera. Lava flows can be seen rising from the sea, and if weather conditions allow, the skipper can stop at a clear-water beach on the island’s south side. Next, the boat sails to Thirassia island on the west side of the volcano. This area shows layers of volcanic eruptions and has clear waters suitable for swimming or snorkeling. Guests spend about ninety minutes swimming or snorkeling while the crew prepares a lunch made from local traditional products, which is served after the swim. The final part of the trip is a cruise along the village of Oia, known for its white buildings and blue-domed churches on the Caldera cliffs. The boat passes Ammoudi village and sails along the full length of Oia, offering views of the village from the water. The rental includes towels, snorkeling gear, and lunch made from local ingredients. Entrance fees are not included. Guests should inform the operator of any dietary needs when booking and specify whether they prefer a morning or afternoon departure from Santorini Old Harbor. It is recommended to wear a black or old swimsuit because the sulfur in the hot springs may discolor swimwear.
Santorini Old Harbor
The Old Harbor lies beneath Santorini’s capital, Fira. Before 1960, it was the island’s main access point, reachable only via steep steps; now there is also a cable car. This shows how difficult travel was before tourism grew. The harbor is a base for cruise ships, which makes it crowded, but this does not affect the private boat experience.

A stop at Nea Kameni Volcanic Park can be made on request. This park highlights the most recent volcanic eruptions in the Santorini volcano, allowing guests to get a closer look at volcanic features.

Nea Kameni
After explaining the volcanic activity that formed the Caldera, the skipper stops near Nea Kameni for swimming in the thermal springs.

Palea Kameni

20 min
Thirassia
Thirassia is the west side of the Santorini volcano before it splits into three parts. The volcanic layers are visible through the rock formations. Guests can swim and snorkel in clear water. While guests swim, the crew prepares traditional local food to be served afterward.
