Discover the beauty of Koufonisia and Rina's Cave on a full-day boat cruise from Naxos, featuring swimming, local cuisine, and stunning Cycladic scenery.
Taking a boat trip around the Cyclades offers a fresh perspective on Greece’s iconic islands, and this Naxos-based excursion to Koufonisia and Rina’s Cave is no exception. With a well-rounded itinerary that combines scenic cruising, swimming in crystal-clear waters, and authentic local food, it’s a solid choice for anyone eager to experience the islands from the sea.
One of the standout features of this tour is the opportunity to visit Rina’s Cave — a location reachable only by boat that promises a unique swimming and diving experience. Plus, the chance to stroll through the charming villages of Koufonisia adds a cultural touch to the day. The lunch onboard, featuring homemade Greek delicacies, is another highlight, making this a full-package day of fun and relaxation.
That said, there are a few considerations to keep in mind. The trip runs for about 9 hours, which might feel a bit long if seas are rough or if you prefer shorter excursions. It’s also not ideal for pregnant travelers, those with mobility issues, or individuals prone to seasickness. Nevertheless, for lovers of the outdoors, scenic boat rides, and authentic Greek island vibes, this tour offers excellent value.
If your travel style revolves around relaxed adventures that combine nature, culture, and good food, then this cruise from Naxos could be just what you’re looking for. Let’s dive into the details.


The adventure kicks off at Agia Anna Port in Naxos, a convenient starting point if you’re already staying on Naxos. The tour lasts approximately 9 hours, so it’s a full day of sun, sea, and sightseeing. The exact start time varies based on availability, so it’s worth checking in advance.
The boat departs along Naxos’s west coast, offering travelers sweeping views of the coastline as you cruise towards the first stop — Rina’s Cave. The journey there takes about 1.5 hours. The cave itself is a highlight and a must-see for adventure lovers. It’s a magnificent location only reachable by boat, offering an excellent opportunity to swim in its waters, which are reportedly clear and inviting.
One reviewer mentioned that the cave is perfect for swimming and diving, with some daring guests jumping from above into the water. The nearby pebble beach, with a natural water spring, adds to the intrigue, and many find the whole experience both scenic and invigorating. The stop here is about an hour long, giving plenty of time to enjoy, explore, and snap photos.
Next, the boat heads to Kato Koufonisi, where a delicious BBQ lunch is served onboard. The food is made from homemade Naxian ingredients, and there’s a good selection to cater to vegetarians and vegans. The inclusion of local wine, water, and soft drinks makes the meal feel like a true Greek feast without extra cost.
Following lunch, the boat visits Ano Koufonissi, with about 2 hours of free time. This is your chance to stroll through the quaint village, pop into shops, or relax on the nearby beaches. Several reviews highlight how well-organized the experience is, and some guests appreciated the optional sea taxi service that makes it easy to visit other beaches on your own, at a low cost.
After exploring Koufonisia, the boat departs around 5:15 pm to head back towards Naxos. You’ll arrive at Agia Anna port by 7:00 pm, just in time to freshen up after a day on the water.

Throughout the trip, you’ll be accompanied by a host or guide who speaks English. Reviewers mention the crew as friendly, careful, and attentive to passenger needs. Although there’s no formal commentary or guide explaining the sites, the crew’s friendly attitude and organization make the experience smooth and enjoyable.
The onboard lunch is frequently praised as authentic and tasty, with locals making sure vegetarians and vegans have options. The drinks during lunch are included, which adds to the laid-back, all-inclusive vibe.

The trip isn’t suitable for pregnant women, people with mobility issues, or those prone to seasickness. The open sea, long duration, and boat nature mean it’s best suited for those comfortable on the water and eager for a full-day adventure.

Many travelers have shared glowing reviews, emphasizing the stunning scenery, friendly staff, and delicious food. One reviewer noted that there’s no commentary, so it’s more of a leisurely cruise than a guided tour, which suits those who prefer a relaxed, unstructured day.
Another mentioned that the boat’s space and cleanliness made the experience comfortable. The free time in Koufonisia allows for independent exploration, which many travelers find invaluable, as it offers a perfect balance between guided activity and personal adventure.
If you’re after a laid-back day filled with scenic views, swimming, and authentic Greek cuisine, this cruise is ideal. It’s perfect for couples, friends, or solo travelers who enjoy a social yet relaxed environment. The trip’s focus on natural beauty and local flavor makes it a great choice for those wanting to see lesser-known spots like Rina’s Cave and Koufonisia’s charming villages.
However, if you’re sensitive to seasickness or require mobility assistance, you might want to consider other options. The long duration and sea-based nature mean it’s best suited for adventurous, seaworthy travelers looking for an authentic Cycladic experience.
This Naxos boat cruise to Koufonisia and Rina’s Cave strikes a great balance between adventure, relaxation, and culture. The inclusion of a home-cooked lunch and the opportunity to swim in remarkable locations elevate it past many typical island tours. The friendly crew, scenic routes, and flexible stops make it a good investment for those keen to experience the Cyclades from the water.
While the trip’s length and the lack of guided commentary might not suit everyone, it’s a fantastic way to enjoy Greece’s famous islands with minimal fuss and maximum authenticity. Whether you’re after a fun day of sunbathing, exploring quaint villages, or snapping memorable photos of Rina’s Cave, this cruise offers a memorable slice of Greek island life.
