Where to stay: I stayed at Avra's Studios. It was a last minute reservation. Skyros has a number of good hotels to choose from. There is also a big number of small houses that you can rent per night.
Where to swim: Pefkos beach, the most beautiful one. Kyra Panagia nice sand beach feels like being in Cyclades island with a beach bar and sunbeds and umbrellas. Molos is huge with two nice beach bars. Juicy is the most famous. Agios Petros and Kareflou are smaller and secluded ones.
What to see: Skyros Town is beautiful and nice to walk. Skyros' small horses are also famous and make sure you ride before you go. You may find them at Restaurant Mouries and to the way to the airport.
