The Müstair valley is one of Switzerland's most beautiful mountain valleys – and is home to the worldwide unique biosphere reserve in the Romansh language region.
The Rom flows through the through the 18-km-long Münster Valley in many guises: sometimes as a placidly winding brook in flower-covered meadows, sometimes as a thundering mountain stream between pebble banks and riverside woodland.
Hiking tour from Fuldera to Santa Maria in Müstair along the Rom embedded in a landscape of great variety. This mountain stream has retained its untamed nature, rushing freely and unfettered through the landscape. Six idyllic villages dot this 18 km long valley, each defined by a charm all its own.
