Crete, Greece Sarakinas Canyon - September and October: These are better months as the weather is not as hot anymore. The sea is still really warm and there are far less tourists. The Cretans - especially the ones who work with tourism - although tired from the summer season are getting more relaxed. It is also one of the preferred period for hikers. One drawback is that as it has not rained for several months the nature is really dry.
Zakynthos Island, Greece. - The most famous landmark of the island is the Navagio beach. It's a cove on the southwest (northwest near village of Anafonitiria) shore, isolated by high cliffs & accessible only by boat. The beach & sea floor are made of white pebbles, and surrounded by turquoise waters. It's named after a shipwreck (MV Panagiotis), which sunk on the shore around 1980.
