One of the loveliest in Greece, with smooth boulders, striking rock formations like the enourmous Petra with its centre arch and blue-gree waters. Access is by boat only, from the harbour or in your own. There is nothing ther so take your food and water. If visiting Skiathos then I can highly recommend a trip to Lalaria beach. The beach itself can not be reached by road, the only way to get there is by boat, because of this it is beautifully undisturbed (a man with a cool box is the only commercial thing you will find there!). It is made up of white pebbles and the sea is clear blue, it really is a gorgeous beach to visit in Skiathos. If you don’t fancy hiring a boat yourself then there are many boat trips which stop at Lalaria beach on their tour round the island. I chose the trip that left Troulos and picked up in Koukinaries in the morning for around €15 and dropped you back mid-afternoon.
