Aegina, Poros and Agistri boat trip from Kinetta with optional lunch

You'll board the boat at Hotel Kinetta Beach and set sail into the Saronic Gulf. Your first port of call will be Aegina, whose maritime prowess once rivalled that of Athens, and is now one of the main pistachio producers in Greece. The island is famous for the hilltop Temple of Aphaia, too, and you'll have time to visit if you wish. Next up is Poros, where, if you book the option with lunch included, a taverna meal will be followed by some free time. Stroll around the main town, built on the slope of a hill, before boarding the boat towards your final stop at Agistri. The island's forest-topped interior and bright blue coves provide the perfect respite for the afternoon heat – and plenty of refreshing swimming opportunities.
