Exploring Rina’s Cave and Koufonisia by Boat: A Full-Day Adventure from Naxos
If you’re after a day of sun, sea, and stunning scenery around Naxos, a group cruise to Rina’s Cave and Koufonisia offers a memorable way to see some of the Cyclades’ best. This roughly nine-hour outing, run by MTM TOURISM GREECE OE, packs in impressive sights, a tasty BBQ, and plenty of water-based fun. While the trip is generally well-loved, it’s not without a few quirks — mainly around the timing for each stop and the communication from the crew.
What I particularly like about this excursion is how smoothly everything is organized — from the easy-to-find meeting point at the Naxos port to the included lunch that caters to vegetarian and vegan diets. Plus, the chance to swim in Rina’s Cave’s crystal-clear water or wander the charming streets of Ano Koufonisi makes it feel genuinely worth the price. On the flip side, some travelers mention that the bulk of the day is spent traveling rather than sightseeing, so it’s good to set expectations accordingly.
One fun detail I love is that the tour combines scenic boat rides with opportunities to stretch your legs on small islands and enjoy authentic local flavors. If you’re looking for a day of relaxed exploration and breathtaking views, this cruise hits the mark. Just keep in mind that if you’re hoping for a leisurely, all-day exploration with lots of stops, this might be more of a scenic boat trip with a few sightseeing highlights — but it’s a solid choice for experiencing the Cyclades from a different perspective.

- Included Lunch: BBQ with vegetarian and vegan options adds great value, especially in a day filled with activity.

Rina’s Cave: The First Stop
The tour kicks off with a visit to Rina’s Cave, located on the southern coast of the islands. This spot is truly a highlight, especially if you’re into swimming and snorkeling. The cave is situated by an unspoiled beach with exotic green waters, a phrase that perfectly captures the striking color palette. The cave itself has some bird nests and a spring providing fresh water, adding to its natural charm. Expect to spend about 1.5 hours here, giving ample time to snap photos, take a dip, or simply soak in the scenery.
One reviewer, Gabriel, calls Rhina’s Cave “unforgettable,” emphasizing the gorgeous blue waters. Others note that the cave visit is relatively brief but sweet, a perfect quick escape into nature after a scenic boat ride.
Kato Koufonisi: The Middle Stop
Next, the boat heads to Kato Koufonisi, often described as a “paradise island.” Here, the scenery is truly special — turquoise waters, golden sands, and the quiet calm of a less crowded island. The two-hour stop means you can relax on the beach, take photos of the Cycladic architecture, or even hire a boat for further exploring. Several reviews highlight how scenic and peaceful this island feels, making it a highlight of the trip.
Ano Koufonisi: The Cultural and Historical Touch
Finally, the cruise arrives at Ano Koufonisi, the smallest inhabited island in the Cyclades.

Some travelers mention the town’s authentic feel and its picturesque setting, perfect for a relaxed afternoon.
Return and Reflection
The boat returns to Naxos in the late afternoon, with most travelers feeling they’ve had a full day of water, scenery, and light exploration. The included BBQ lunch is served on board, with a good balance of options. As one reviewer notes, “the food was simple but delicious,” adding to the sense of casual comfort rather than fine dining.
Who Is This Tour Best For?

This cruise suits those who want a taste of the Cyclades’ natural beauty without the stress of navigating islands alone. It’s ideal for travelers who value scenic boat rides, swimming, and a relaxed pace, rather than in-depth sightseeing. The inclusion of a BBQ lunch and drinks makes it a good value for the price — around $85 — especially considering the transportation, snacks, and island visits.
If you’re traveling with a group, family, or even solo but want to experience Greek islands from the water, this tour offers a straightforward and enjoyable experience. Be prepared for some travel time between stops, and note that the route could shift depending on weather conditions — flexibility is key.
Practical Tips for Making the Most of Your Day

- Bring sun protection: Hats, sunscreen, and sunglasses are essential when spending hours outdoors.
- Arrive early: The meeting point is straightforward but arriving on time ensures you don’t miss the boat.
- Expect a casual atmosphere: The boat is comfortable but not luxurious; it’s about enjoying the day, not fine dining or high-end service.
- Prepare for water activities: Bring your snorkel gear or rent boats at Koufonisia if you want extra adventure.
- Set your expectations: The tour is scenic with some water fun and island exploration, but don’t expect a deep cultural tour.
Price and Value Analysis

At $84.94 per person, this cruise offers decent value, especially considering the included boat ticket, BBQ lunch, and drinks. Compared to similar day trips, the price reflects the convenience of everything organized for you. For those who appreciate scenic water travel, stunning island views, and a relaxing day on the water, it’s a good deal.
However, some reviews point out that a significant portion of the day is spent traveling between stops, so if you’re looking for an intensive sightseeing experience, you might find it a bit limited. Still, for an overall taste of the Cyclades’ top spots, it’s hard to beat.
