Spetses is a small island but it has enough to keep you busy for a week, or at least for a long weekend. Close to Athens and well connected, so you will not face troubles in transportations. The port is very picturesque and I liked it ever more at nights, with the small lights like candles. Best beaches Agia Paraskevi and Agia Marina. Go to the beaches by taxi boats. The special thing is that on Spetses there are no cars, only carriages and bikes for your transport.
