The river Doubs lends its name to Doubs Nature Park. Forty kilometers long, the river forms the border of the French Departement bearing the same name. To the south, the Freiberg Mountains with their typical forest and meadow landscape are part of the 300-square-meter Nature Park.
Splügen lies at the foot of the Splügen Pass and its idyllic village image is well known far beyond the regional borders.
