Take a day cruise from Athens to the fabulous Greek islands of Hydra, Poros and Aegina for a relaxing day on the sea. With all your transport, transfers and buffet lunch organized, you can sit back and enjoy your leisurely day cruise with free time on each island to explore. After transferring from Athens to Piraeus by motor coach, you'll set sail for the island of Poros, where you'll have free time for strolling and shopping .   Next, it's on to the island of Hydra. You will have about 1 hour and 45 minutes at leisure to enjoy the unique charms of Hydra island, whose amphitheater shape once served as a safe shelter for Saronic Pirates. From the decks, you will be able to admire the very special architecture and dramatic landscapes of this island, whose old traditional stone houses and mansions silently stand witness to a long and turbulent history.   Upon arrival in Egina (Aegina) you can either join an excursion to the Temple of Aphaia (cost not included) or take a walk around the main town. Aegina is one of the Saronic islands of Greece in the Saronic Gulf. The lovely island is only 31 miles (50 kilometers) from Athens, and is a popular getaway for Athenians during the summer months.   After sailing back to Piraeus port you'll be transferred to Athens.
