Getting there

The airport and ferry ports of the island as our sources record them. We do not copy timetables or fares, because they would go stale; where an official source exists it is linked below.

The island has no airport on the list of commercial airports. The nearest is Paros National Airport (PAS), on the island of Paros, 36.3 km in a straight line from the main town. The journey is not a straight line and may cross water. Airport page

The number of terminals shows how closely the harbour is mapped, not how large it is or how many ferries call.

Sea: NOAA OISST v2.1, period 1991–2020, nearest cell about 15 km away (0.25 degree grid). Daylight: calculated for the 15th of each month. These are regional model values and typical conditions, not a forecast.

Beaches

The 11 official sites with the most seasons of Excellent water since 2011; ties are settled by the latest classification (2024 season). It is the EU's classification by season, not a reading on the day.

Also mapped, not officially monitored

Named beaches in OpenStreetMap that are not on the official bathing-water list. They have no water class in our data, which says nothing about how clean the water is.

Nature and land

The land of the island

Open/natural land (grassland, bare ground) 75%, Water 10%, Woodland or shrubland 10%.

Source: ESA WorldCover 2021, a 10 m satellite classification generalised to a ~1 km grid and counted inside the island's outline. Shares are rounded to 5% and describe what covers the ground, not land use or building rights. On small islands the grid is coarse and coastal cells may read as water.

How the numbers were counted

The island is a place=island outline in OpenStreetMap and its area is computed from it. Settlements, beaches, airports and ports belong to the island when their point lies inside the outline (or, for beaches and ports, up to 250 to 500 m outside it).

A municipality counts as being on the island when its seat or main town is there, or when at least half of its settlements are. A port is a group of ferry terminals mapped in OpenStreetMap within 1 km of each other; the name is the nearest settlement.

The page exists because the island has a city, town or village (or a hamlet with an official bathing-water site or a ferry port) and at least two of: an official bathing-water site, a port or airport, a settlement with a page of its own, a Wikidata item.
