Snorkeling in Santorini: Sunset Catamaran with Hot Springs

Swim and snorkel at four stops while the catamaran sails the caldera.

A sunset sailing catamaran in Santorini where you snorkel at Red and White Beaches, swim in the geothermal Hot Springs, and watch the volcano and lighthouse from the water. The boat departs from Amoudi Bay, includes a barbecue meal and local wine, and returns you to your hotel. A morning option is also available if you prefer to skip the sunset.

The experience

The catamaran leaves Amoudi Bay and sails past the Santorini Volcano, staying close enough to see the ancient lighthouse and the landscape of Palea Kameni. You'll swim and snorkel at Red Beach first, where the water is deep and clear, then move to White Beach for a second snorkel stop. The crew has chosen the best points for entry since catamarans can't moor directly on the sand. They anchor as close as the depth allows.

The Hot Springs are the centerpiece: the catamaran stays 50 meters from the warm yellowish water, which runs about 4 degrees warmer than the surrounding sea. You swim out to it, feel the temperature shift, and float in water that's been heated by the volcano beneath. Snorkeling equipment is provided, along with floating devices if you need them. The boat carries up to 55 passengers, so the stops don't feel crowded.

A freshly prepared barbecue meal is served on board, with vegetarian options available. Complimentary drinks include a selection of local Santorinian white wine, water, and soft drinks throughout the trip. The sunset happens from the water, with the caldera as the backdrop. The whole experience runs about five hours, and the crew confirms your hotel pickup time the day before departure.

Top questions

What languages is the guide in?

Live guide in English and Greek.

Can children come?

Yes. Ticket types: Child (4 to 10 years); Infant (under 4): free.

What happens if it rains?

It may be canceled due to bad weather. If that happens, you're offered another date or a refund. Free cancellation up to 24 h before the start.

What exactly happens at the Santorini Hot Springs when we snorkel there?

The Hot Springs are warm geothermal water that rises from the seabed near the volcano. The catamaran anchors 50 meters away, and you swim out to the yellowish water, which is noticeably warmer than the surrounding sea: about 4 degrees Celsius higher. You can float and snorkel in both the warm springs and the cooler water around them.

Can I snorkel if I've never done it before?

Yes. Snorkeling equipment is provided, and floating devices are available on board. The crew selects the safest and calmest spots for entry, and the tour is suitable for all physical fitness levels. Children and infants can come along too.

Is the barbecue meal included, or do I pay extra?

The barbecue meal is included on board, with vegetarian options. Complimentary drinks (local white wine, water, and soft drinks) are served throughout the five-hour cruise.

Does the price include getting to and from my hotel?

Yes, roundtrip hotel transfer is included. The crew will confirm your pickup time one day before the cruise, so you'll need to provide your contact details and hotel location when you book.

What's the difference between the morning and sunset options?

Both tours visit the same stops (the volcano, Hot Springs, Red Beach, and White Beach), and include the same meal and drinks. The sunset tour watches the sun go down from the water. The morning tour skips the sunset but gives you the full day of snorkeling and swimming earlier.

What should I bring or wear?

Wear swimwear under your clothes. The operator recommends bringing sunglasses, a sunhat, sunscreen, dry clothes, and a light jacket. You'll remove your shoes before boarding. Towels are not provided, so bring your own. A blanket is available on board and returned to the crew at the end.
