Discover the beauty of the Saronic Gulf with this full-day cruise to Aegina, Agistri, and Metopi, featuring swimming, scenic views, and a Mediterranean buffet.
Taking a boat trip around the Saronic Gulf is one of those standout options for anyone visiting Athens who wants to escape the hustle and see a different side of Greece’s central coast. This cruise, offered by Key Tours, promises a full day of swimming, scenic island stops, and a delicious Mediterranean buffet—something that most travelers find both relaxing and rewarding.
What we love about this experience is its combination of stunning scenery, manageable group size, and the chance to feel like a local while exploring three charming islands. The boat’s outdoor deck with sun loungers and beanbags makes for a wonderfully laid-back atmosphere, perfect for soaking up the sun while cruising through turquoise waters.
However, one thing to keep in mind is that, depending on the day, the schedule might feel a little rushed, especially if you want to spend more time exploring each island. Still, this tour is ideal for travelers who want a taste of island life without the hassle of planning multiple transport connections and who prioritize swimming and scenic views over in-depth sightseeing.
Whether you’re a first-time visitor eager to tick off multiple islands or a seasoned traveler craving a relaxing boat day, this cruise offers a practical and enjoyable way to experience the Athenian Riviera at a reasonable price.

The experience kicks off at Marina Kallitheas, with the boat called Platytera. Pickup options are available, and the tour is designed to be flexible with starting times, but always check in advance for your specific schedule. Since the tour lasts around nine hours, you’ll want to plan for a full day of relaxation and exploration.
The group size is typically manageable, with reviews highlighting that the crew is friendly and attentive. Some reviews mention that the staff speaks multiple languages including English, French, Italian, and Spanish, making it accessible for international travelers.
The day begins with a cruise that lasts about 105 minutes, giving you your first sweeping views of the coast and a good chance to settle into the boat’s lively yet relaxed atmosphere. This initial cruise sets the tone—beautiful views, gentle sea breeze, and anticipation for the stops ahead.
Next, the boat arrives at Agistri, one of the most praised islands. With about two hours of free time, you can explore, shop for souvenirs, or simply relax on the beaches. Reviewers rave about Agistri’s less crowded, peaceful vibe and pristine beaches, perfect for swimming and snorkeling. One guest mentioned, “The islands were beautiful and not crowded. Cute little shops and restaurants, and the beaches were lovely.”
On the way to Nisis Metopi, the boat cruises for about 20 minutes, offering another scenic perspective of the coastline before anchoring for a swim. At Nisis Metopi, you’ll spend around 40 minutes swimming in clear waters—an activity many find the highlight of the day. Reviewers confirm the water quality is outstanding, with one noting, “The water was completely clear no matter how far I swam out off shore.”
The cruise then moves on to Aegina, the largest of the stops, with around 105 minutes for sightseeing, shopping, and more swimming. Aegina offers a charming blend of traditional Greek culture and scenic beauty, perfect for strolling and soaking in local life. Guests often mention the town’s authenticity and the variety of small shops and cafes.
In late afternoon, the boat returns to the Saronic Gulf for about 105 minutes of scenic cruising, during which you’ll enjoy drinks, music, and a lively atmosphere—perfect for unwinding after a day of exploration. One reviewer called this part “the rise back to Athens with the DJ and everyone dancing,” highlighting that the cruise doubles as a mini party.
The included Mediterranean buffet is described as fresh and flavorful, with plenty of vegetarian and vegan options. Although some reviews suggest the lunch is “nothing special,” most agree it’s perfectly adequate for a day on the water. Unlimited soft drinks, wine, coffee, and spirits are available throughout the cruise, making it easy to toast the views or simply stay refreshed.
Reviewers have particularly enjoyed the selection of drinks, with many appreciating the free-flowing wine and cocktails during the scenic cruising segments. The onboard bar seems to be a hit, especially with a DJ playing during the final stretch back to Athens.
The tour wraps up with a drop-off at multiple locations across Athens. This widespread drop-off service is very convenient, saving travelers the hassle of organizing transport after a long day.

Based on numerous reviews, what really makes this experience stand out is the friendly crew and their ability to keep everyone comfortable and entertained. Many guests mention the crew’s helpfulness, from organizing swimming gear to providing informative commentary about each island.
The scenic swimming stops are another favorite aspect—clear waters that make for excellent snorkeling and relaxing on beaches with minimal crowds. Guests also love the laid-back vibe onboard, where you can lounge on beanbags or dance to the DJ tunes.
While most reviews are glowing, a few mention that the lunch could be more memorable, and some wished for longer beach time at Agistri. The large ferry boat, while stable and less prone to seasickness, may not have the intimate charm of smaller vessels, and you might miss out on some of the classic small-boat “adventure” feel.
It’s worth bringing your beach towels, as some guests note that towels and sunscreen can be overpriced on the boat—so pack these essentials from the start. Also, if you’re looking for in-depth island exploration, this tour provides more of a snapshot than a deep dive.
This cruise is ideal for anyone looking for a relaxed, scenic day with swimming, good food, and island views. It suits travelers who want a balance of sightseeing and leisure, especially those who prefer not to navigate public ferries or hire private boats.
Families, couples, and groups of friends all find it a fun and practical way to see multiple islands without breaking the bank. It’s also a great choice for first-timers to Greece wanting a broad taste of the Athenian Riviera.

This cruise offers a fine balance between scenic beauty, relaxing swimming opportunities, and a lively atmosphere onboard. You’ll love the unlimited drinks, the friendly crew, and the chance to visit three different islands in one day—each with its unique charm. For a reasonable price, you get a full day of sun, sea, and Greek culture without the stress of planning or organizing transport.
While not a deep cultural dive, the tour provides enough time to enjoy the stunning coastlines, take plenty of photos, and swim in beautifully clear waters. It’s particularly appealing for those who want a lively, fun-filled day with a bit of everything—scenery, swimming, good food, and a party vibe on the way home.
This cruise is a smart pick for travelers who prioritize comfort, value, and a taste of island life, all wrapped into one memorable day on the water.
