Skiathos is a small Greek island situated in the northwest Aegean Sea, serving as the westernmost landmass of the Northern Sporades archipelago. Located east of the Pelion peninsula in Magnesia and west of Skopelos, it functions as the primary entry point for the region due to its sole airport and status as the first port of call for most ferries. The island features a north-south axis, measuring approximately 12 kilometres long and 6 kilometres wide, with an indented coastline comprising inlets, capes, and peninsulas that define its geographical character.
