The experience

You're picked up from your hotel and driven to Amoudi port, where the catamaran departs mid-morning. The boat sails close to Santorini's volcanic cone and Palea Kameni, giving you a clear view of the island's geological spine from the water. The crew then anchors 50 meters from the hot springs: close enough to swim in water that runs about 4 degrees warmer than the surrounding sea, heated by volcanic activity beneath the surface. You float in the thermal zone with the volcano rising behind you, a sensation most swimmers don't forget.

After the hot springs, the catamaran moves to White Beach, where you swim and snorkel in the coastal waters while the crew prepares a Greek barbecue on board. The menu includes pork skewers, roasted vegetables, pasta with red sauce, stuffed vine leaves, grilled chicken, Greek salad and shrimp saganaki, with a vegetarian option available. Soft drinks, white Santorinian wine, beer, bottled water and juice flow throughout the afternoon. You then sail to Red Beach for a final snorkel session, passing the old lighthouse on the way. The tour ends at Vlychada port around late afternoon.

Snorkeling equipment, towels and a floating device are provided. The crew has chosen the best points for visibility and safety based on conditions that day. A map with information about the landmarks and a leaflet with safety instructions in multiple languages come with your booking. Shoes come off before you board, and the restroom is accessible throughout the cruise. The catamaran's design (sleek and diamond-shaped) offers comfortable seating both inside and out, so you can move between sun and shade as the afternoon wears on.

What is the Santorini hot springs swim actually like?

The hot springs are thermal waters heated by volcanic activity beneath the seafloor, running roughly 4 degrees warmer than the clear water around them. The catamaran anchors 50 meters away for safety, and you swim in the yellowish thermal zone with the volcano visible from the water.

Can I snorkel at both beaches, or do I choose one?

You snorkel at both White Beach and Red Beach during the same tour. White Beach comes first, after the hot springs, and Red Beach is the final snorkel stop before the boat returns to port.

Is the barbecue lunch included, and what if I'm vegetarian?

Yes, a Greek barbecue prepared on board is included, with pork skewers, roasted vegetables, pasta, stuffed vine leaves, grilled chicken and Greek salad. A vegetarian meal option is available. Let the crew know when you board.

Do I need to bring my own snorkeling gear?

No. Snorkeling equipment, towels, floating devices and a blanket are all provided. Towels and the blanket are returned to the crew at the end of the tour.

How many people typically sail on this catamaran?

The boat carries a maximum of 20 passengers, so the group stays small enough to move around the deck and access the water without crowding.
