A typical full-day boat tour from Athens takes you into the Saronic Gulf to visit three islands: Hydra, Poros, and Aegina. Expect about 9–10 hours total, with roughly 1.5–2 hours on each island and long stretches of sailing in between. The boat itself is usually a large tourist vessel (sometimes a wooden-style sailing ship) carrying 100–400 people. You get basic lunch, loudspeakers with commentary, and stops long enough for a quick walk, coffee, or swim. The views are genuinely good once you clear Piraeus, especially the approach to Hydra, but the experience is very much group tourism rather than a quiet sail.
Best time is late spring (May–early June) or early autumn (September–mid October). July and August are hot, crowded, and the boats feel packed. Expect to pay around $130–$180 per person for a standard full-day cruise including transfer from central Athens, onboard lunch, and basic drinks. Smaller sailing boats or semi-private options usually start around $220 and go up from there.
Pick the classic three-island route if it’s your first time; it’s the most established and gives the best mix of scenery and time ashore. Skip the ones that add “swimming stops” in high summer – the boat is usually late and the stops are rushed. If you get seasick easily, take something beforehand; the Saronic Gulf can get choppy in the afternoon meltemi winds.
