Snorkeling in Naxos: Koufonisia and Rina's Cave from Agia Anna

Snorkel three islands and a sea cave in one day, with the boat handling the route

A full-day cruise from Agia Anna's Port in Naxos visits Kato Koufonisi, Ano Koufonisi and Rina's Cave, with snorkeling equipment provided and time to explore each stop. The boat departs daily, includes a BBQ lunch with local meat and salads, and free water, soft drinks, juice and wine throughout the journey. You snorkel in the cave's waters and spend roughly two hours at each island beach.

The experience

You board at Agia Anna's Port and the boat heads south toward the Koufonisia islands. Before arrival, the crew serves Naxos graviera cheese with tomatoes and island bread: a first taste of what the day includes. The route itself is the itinerary: no long coach rides, no switching between transport types, just the sea between stops.

At Kato Koufonisi you have about two hours on the beach with snorkeling equipment already on board, free to use. The water here is where most travelers spend their time in the shallows and reefs. After, the boat moves to Ano Koufonisi for at least two more hours to explore on foot or from the water. Throughout the cruise, water, soft drinks, juices and wine arrive without asking. The crew grills pork and poultry with olive-oil salads for lunch. Coffee and cocktails cost extra if you want them.

The final stop is Rina's Cave, where you swim and snorkel directly into the cave's waters: the single moment most travelers mention when they describe the day. Naxos seasonal fruits come out near the end, and music plays across the hours on deck. The full day runs roughly nine and a half hours from departure to return.

Top questions

Can children come?

Yes. Ticket types: Child (6 to 11 years); Infant (under 6).

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.

How much time do I actually spend snorkeling versus sitting on the boat?

Kato Koufonisi and Ano Koufonisi each give you about two hours to be in or near the water with the snorkeling gear. Rina's Cave is the third snorkel stop. The rest of the day is sailing between islands and eating, so you're not rushed through any one place.

What is Rina's Cave like when you get there?

Rina's Cave is a sea cave where you enter by swimming and snorkeling in its waters rather than walking inside on land. It's the unique stop the route builds toward, and the crew times the arrival so you have time to explore it without feeling hurried.

Is the snorkeling equipment included, or do I need to bring my own?

Snorkeling equipment is provided free of charge and already on the boat when you board, so you don't need to arrange or carry any.

What if I don't want to snorkel? Can I just swim or stay on the beach?

The equipment is there if you want it, but you're free to swim without it or stay on the beach at Kato Koufonski and Ano Koufonski. At Rina's Cave, snorkeling is how you explore the cave itself.

Does the price include lunch and drinks?

Lunch is included: a BBQ with local pork and poultry, salads with olive oil, and seasonal Naxos fruits. Water, soft drinks, juices and wine are free throughout the day. Coffee and cocktails cost extra if you order them.

What time does the boat leave and return?

The boat departs daily from Agia Anna's Port. The full journey is about nine and a half hours, so departure and return times depend on the season and the operator's schedule. Check when you book for the exact times.
