Discovering Santorini from the Water

Seeing Santorini from the deck of a boat gives you a whole new appreciation for its dramatic landscape. The cliffs of Oia, with their whitewashed buildings spilling down the hillside, look even more spectacular when viewed from the water. As we gently cruise past, the colors—white, blue, and volcanic black—create a postcard-perfect scene that photographs just can’t fully capture.

Your captain, who is likely to be friendly and knowledgeable, will steer the boat around the volcano, offering unique vantage points that you simply can’t get on land. As you sail past the tiny island of Thirassia, you’ll notice its quieter, more untouched atmosphere—an authentic slice of local life away from the tourist-heavy Santorini.

The Swim in Saint Nicholas Church Waters

A highlight for many is the stop near Saint Nicholas Church. Here, the waters are invitingly clear, with a gentle swell perfect for a quick dip. If you enjoy snorkeling, you’ll find the gear provided makes it easy to explore underwater life. Reviewers mention that the water is “crystal clear” and that the experience is refreshing after a hot day exploring the island.

This swim is not just about cooling off; it’s an opportunity to relax and take in the scenery from a different angle. You might find yourself floating with the iconic church in sight—an image many travelers cherish and share.

The Hot Springs Experience

The final stop at Santorini’s natural Hot Springs is what many travelers set out for. The waters here are heated by volcanic activity, offering a warm, mineral-rich soak. Many find this a surprisingly therapeutic experience—some mention that the waters are “warm and soothing,” perfect for easing tired muscles after hours of sightseeing.

Keep in mind, the hot springs can be crowded during peak times, and the waters may have a sulfur smell, which is natural but something to be aware of if you’re sensitive to odors. Still, the feeling of floating in warm, mineral-laden waters with the volcano looming nearby is quite special.

What’s Included and What to Expect

The tour is designed for comfort and convenience. Your package includes life jackets, towels, snorkeling gear, noodles, as well as a toilet and shower on board—important details for a short cruise. You’ll also get a glass of local wine or a soft drink, adding a relaxing touch to your experience.

The boat is captained by a professional, and since the tour is for a private group, it offers a personalized touch that larger cruise ships can’t match. The experience is in English, making communication straightforward.
