Springs and streams abound, and there are also two small lagoons. The length of Skiathos' coastline is a remarkable 44 kilometres. It consists of successions of coves and bays that feature more than 60 beaches which offer some of the best swimming in Greece. There are several smaller islets around the island. There is just one major road, leading from the town down along the south coast to the many small bays and beaches.
Transport is by bus or taxi.
The north coast is less easily accessible, while the island's verdant and hilly interior is ideal for walking in spring when the flowers and bushes are blossoming. Skiathos enjoys almost constant sunshine during the high season. A two kilometres long stretch of golden sand, azure water and green pines, Koukounaries is probably the most famous beach in Greece. If there is only one beach you can visit, this is it. Behind the pine forest lies the lagoon of Strofilias, an important location for migrating birds.
