Itinerary

The cruise departs in the morning from Agia Anna Port in Naxos, where you board a traditional excursion boat and set sail toward the Small Cyclades. After a scenic crossing, the first stop is typically Kato Koufonissi, a quiet, uninhabited island known for its clear waters and ideal swimming conditions.

The journey continues to Ano Koufonissi, where you’ll have time to explore the small harbor village or relax at nearby beaches like Ammos. In the afternoon, the boat heads back toward Naxos, stopping at Rina Cave, a sea cave accessible only by boat where guests can swim in emerald waters and snorkel around the rocky entrance.

During one of the stops or while anchored, a fresh BBQ meal is served onboard, accompanied by local wine and refreshments before returning to Naxos in the late afternoon or early evening.

Who is this experience best for

This cruise is ideal for travelers who want a classic Aegean island-hopping experience in one day without planning multiple ferries. It suits couples, families, and groups who enjoy swimming, relaxed boat time, and visiting both inhabited and uninhabited islands in a single itinerary.

Insider notes

This is one of the most popular day trips from Naxos, especially in summer, and boats can reach high capacity. Expect a structured schedule, where time at each stop is limited but well-organized. Koufonissia is often a highlight, but some travelers prefer it as an overnight stay if they want more time on land.

Sea conditions can affect the order of stops, especially at Rina Cave, which may be adjusted depending on wind and safety. Bringing water shoes, sunscreen, and a waterproof bag is strongly recommended since most of the day is spent in direct sun and saltwater.
