Skiathos is a pine-covered island in Greece's Sporades group, in the northwest Aegean, known for its beaches and lively harbor town, and a rental car is a genuinely useful way to reach the island's scattered coves once you are past the short walk from arrivals. Skiathos Island National Airport (JSI) sits close to Skiathos Town, notable for its short runway that brings landing aircraft in low over a popular beach road, and rental counters here are run by international and local operators, with pickup generally quick given the airport's modest size.
From JSI, Skiathos Town itself is only a few minutes' drive, while the island's famous beaches along the southern coast, including Koukounaries and Lalaria's approach roads, are reached within twenty to thirty minutes along a single main road that loops around much of the island's developed southern half. The northern coast remains far less developed and largely inaccessible by car, reachable mainly by boat, so driving here concentrates on the southern loop connecting the town to its beaches and a handful of hillside villages.
Driving is on the right, as throughout Greece, and Skiathos's main road is paved but narrow and busy in peak season, with heavy pedestrian and scooter traffic near the beaches, so patience and a modest pace suit the island better than speed. There are no tolls on Skiathos, and the island is small enough that most drives take well under an hour regardless of destination. Many visitors combine a rental car with the seasonal ferry network connecting Skiathos to neighboring Skopelos and Alonnisos, useful for day trips, though the car itself typically stays on the island rather than traveling aboard the boat. Fuel stations are concentrated near Skiathos Town, so it is worth topping up before a full day exploring the island's beach roads, particularly in the busy summer months when the harbor area is at its most crowded.
