Discover the Greek islands of Hydra, Poros, and Aegina on a full-day cruise from Athens with sightseeing, free time, and a delicious onboard buffet lunch.
Exploring the Saronic Islands: A Full-Day Cruise from Athens
Taking a day trip from Athens to explore the nearby Saronic Islands is a popular way to escape the city’s hustle and experience some of Greece’s most charming seaside towns. This particular tour, offered by Key Tours, promises visits to Hydra, Poros, and Aegina —three islands with distinct personalities— all packed into a 12-hour adventure. The experience is especially appealing for those who love scenic boat rides, free time for wandering, and a relaxed, all-inclusive vibe.
What we like most about this cruise is the combination of beautiful coastal views from the open deck, the freedom to explore each island at your own pace, and the generous onboard buffet lunch. The fact that you get to hop around three islands in one day makes this a practical choice for travelers short on time but eager to see more than just Athens’ ancient ruins. That said, a potential drawback is the limited time on each island, which might leave those wanting a deeper dive feeling a little hurried.
This cruise suits travelers who want a taste of island life without the hassle of multiple bookings or long ferries—perfect for first-timers or anyone looking for a scenic, well-organized day out. If you’re after a mix of sightseeing, casual exploration, and good value, this tour hits the mark.

The cruise first heads to Hydra, often hailed as the jewel of the trip. The dock is a dramatic scene, with steep slopes and old stone buildings that look straight out of a postcard.

One reviewer praised the guide’s local insights, noting that the boat staff, including a guide named Georgina, was knowledgeable and friendly. The short time means you’ll want to prioritize a quick walk or a visit to a local café for a quick frappe and some people-watching.

You’ll get roughly two hours to explore independently, with options to join a guided tour to the Temple of Aphaia for an extra fee. The temple, perched on a hill, offers panoramic views and a glimpse into ancient Greece.
