The Experience and Its Setting

We begin our journey at the small, picturesque Ammoudi Bay, right below Oia—a favorite spot for those wanting a scenic starting point. The classic catamaran is spacious and well-equipped, promising comfort for the 4-hour voyage. As the boat sets sail, you immediately feel the benefits of being on the water — the breeze and warm sun combine to give a true sense of Greek island life.

The itinerary is crafted to maximize both relaxation and sightseeing, with a balance of time at sea and stops at key volcanic sights. The crew offers informative commentary about the volcanic islands and their history, which adds depth to the experience. We loved how the crew members frequently checked in to refill drinks and ensure everyone’s comfort, which many reviewers appreciated highly.

The Stops: What You’ll See and Do

• First stop: The boat cruises past the world-famous volcanic islets of Nea Kameni and Palea Kameni. These islands are the heart of Santorini’s volcanic activity, and you’ll get a chance to swim in the mineral-rich salty waters. The swim stop at Nea Kameni is a highlight — expect a refreshing dip in unique volcanic waters, perfect for cooling off after lounging on deck.

• Thirassia Island: About 20 minutes here gives you a taste of local life. We loved the opportunity to swim in a different setting and enjoy some local snacks on board. The 40-minute stop allows enough time to enjoy the water and absorb the island’s quiet charm without feeling rushed.

• Photo stops at Fira’s old port and Armeni Bay: These short stops are perfect for snapping photos of Santorini’s dramatic cliffs and traditional architecture. As one reviewer said, “they also come to pick you up to the closest stop,” adding to the ease of the experience.

Food and Drinks: What’s Included

The onboard snacks and drinks are thoughtfully curated. Expect fresh fruit salad and tasty local snacks, complemented by unlimited dry white wine, soft drinks, and water. The reviews rave about the quality of the food and the generous drinks service, making it feel like a floating celebration rather than a simple cruise. The crew’s attentive service — asking regularly if you want refills — adds to the relaxed vibe.
