Official travel information
Routes and connections can change by season. Confirm times and service directly with the operator before travelling.
How the numbers were counted
Each municipality belongs to the region and regional unit that OpenStreetMap records for it, and the figures on this page add up its municipalities. Beaches, airports, ports and sights belong to the municipality that contains them (up to 3 km outside the boundary for those on the shore).
Ports: a port is a group of ferry terminals mapped in OpenStreetMap within 1 km of each other (a harbour is mapped as many berths). The name is the nearest settlement. The number of terminals shows how closely the harbour is mapped, not how large it is or how many ferries call.
Fires: the count covers EFFIS burnt areas (roughly 30 hectares and above) whose reference point lies in a municipality of the area, with dates from 23 Mar 2016 to 12 Sept 2026. Natura 2000: each site is counted once, even when it overlaps several municipalities.
Zone prices: the lowest and highest value among the 2021 objective-system zones whose reference point lies in the area. They are tax values, not market prices.
