Clothes should be light, a sweater or jacket is required at nights on most islands. A hat, sunglasses and plenty of sun protection. A beach towel, the boats do have towels on board but we prefer that these are not used on the beach. And most of all don't forget your camera. Anytype of medication as some of the perscription drugs are not avialable in Greec. The documentation you require to bring is your passport, tickets, your charter contract .
