Islands Near Athens: The Saronic Gulf Day-Trip Guide
The islands and coastline our cruises explore — Agistri's pine-fringed coves, Aegina's pistachio harbour and ancient temples, the crystal swim stops at Moni, and the Athens Riviera. Each guide shows what to see and which cruise takes you there.
The closest islands to Athens are the Saronic Gulf islands— Aegina, Agistri and Moni — all about an hour's sail from Piraeus, which makes them the easiest Greek islands to visit on a day trip from Athens. A single day cruise from Marina Zeas visits all three with swim stops, lunch and drinks aboard, returning by evening (from €134 booking direct). Poros and Hydra are a little farther — better as longer trips — and the Cyclades (Santorini, Mykonos) are too far for a day trip.
