The experience

You board the catamaran in the morning and spend the next nine to ten hours moving between six swimming stops that exist only by water. The boat passes Cape Vani, where manganese mines opened in 1898 and their ruins still mark the cliffs, then anchors at a turquoise bay ringed by green rock where you eat homemade breakfast before the first swim. Sykia Cave, the largest on the island, has no roof, so sunlight floods the emerald water and turns the stone walls into a shifting palette of color. The boat stops at the entrance for photos, then moves on to the next anchorage.

Kleftiko is the old pirate bay, a maze of white volcanic caves carved into a cliff face, and the water there shifts between crystal green and deep blue depending on the light and the depth. You swim and snorkel among the sea caves. The crew hands out snorkeling gear and paddle boards for anyone who wants them. Gerakas is a sandy beach hemmed by geological formations, famous for its hot spring. You can float in warm water while the crew sets up the Greek BBQ on deck, and you eat lunch with the beach and the turquoise water in front of you. The last stop is the Blue Lagoon on Poliegos, an uninhabited island, where a narrow bay with white sand and steep white rocks holds water so transparent it looks unreal.

The boat carries snorkeling equipment, SUP boards, swimming noodles and a GoPro camera for anyone who wants footage of the day. Breakfast is homemade. Lunch is a full Greek menu prepared on board with a vegetarian or vegan option if you request it ahead of time. Drinks run to white wine, beer, juice, water and soft drinks. The crew speaks English and fills the gaps between stops with the island's history: the old sulfur mines at Theiorychia, the fishing village of Klima with its colorful boathouses, the geological story of Cape Vani. Transportation time between stops is built into the nine- to ten-hour total.

Is this one for you?This is a shared boat tour, so you travel with other passengers and eat meals as a group: ideal if you want the social rhythm of a full day on the water and don't want to arrange your own transport between six isolated beaches. The fixed itinerary and nine- to ten-hour commitment suit someone with a full day free and the appetite for multiple swims rather than a quick half-day outing.

Top questions

Can children come?

Yes. Ticket types: Child (under 18).

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 is Kleftiko and why is it worth the boat ride?

Kleftiko is an old pirate bay enclosed by towering white volcanic rocks and riddled with sea caves. The water is crystal green-blue, and you swim and snorkel among the caves and the rock formations. It's only reachable by boat.

Can I paddle board and snorkel on the same day, or do I have to choose?

Both are included and available throughout the day. Snorkeling gear and SUP boards are on board, and you can use them at any of the six swimming stops depending on what appeals to you at each anchorage.

What does the Blue Lagoon on Poliegos actually look like?

The Blue Lagoon is a small, narrow bay on the uninhabited island of Poliegos, walled by steep white rocks and white sand, with water so transparent and light blue it looks like a natural pool. It's the final swimming stop of the day.

Is lunch really cooked on the boat, and what if I'm vegetarian?

Yes, the crew prepares a full Greek menu on board and serves it at Gerakas beach while you're anchored there. Vegetarian and vegan options are available if you request them when you book.

How much time do you actually spend swimming versus traveling between stops?

The total day is nine to ten hours, and that includes transportation time between the six stops. You anchor at each site long enough to swim, snorkel and paddle board. The crew does not rush the water time.

What's included to drink, and is alcohol part of it?

Water, soft drinks, juice, white wine and beer are all included throughout the day. You don't need to bring or pay for drinks separately.
