Only have a few days in Greece but need a taste of island life? Hopping over to one of the Saronic isles is the perfect solution. Called the "offshore islands" by day-tripping Athenians, they are treasured for their proximity to the burly city. Just south of hectic Piraeus, Aegina still feels like another world. Heading southward you'll find chic and cosmopolitan Hydra, a fitting stage for one of Sophia Loren's first forays into Hollywood. Finally, there is splendid Spetses, anchored off mainland Kosta—a playground prized by carefree vacationing Greeks.

The Saronic Gulf islands, whose ancient city-states rivaled Athens, are now virtually a part of the capital. Aegina, one of the most-visited islands in Greece because of its proximity to the capital, is 30 minutes from Piraeus by hydrofoil, while Spetses, the most "remote" and the greenest of the Saronic islands, is 120 minutes away. South of the Argolid, the peninsula that divides the Saronic Gulf from the Gulf of Argolis, rests Hydra, poor in beaches but rich in charm.

Aegina’s pretty country villas have drawn shipping executives, who often commute daily from the island to their offices in Piraeus. Here pine forests mix with groves of pistachio trees, a product for which Aegina is justly famous. Hydra and Spetses are farther south and both ban automobiles. Hydra’s stately mansions, restaurants, and boutiques cater to the sophisticated traveler and art lover. Spetses has both broad forests and regal, neoclassical buildings. Rather than being spoiled by tourism, all four islands have managed to preserve their laid-back attitude, well suited to the hedonistic lifestyle of weekend pleasure-seekers arriving by yacht and hydrofoil.
