From July to October

Biosfera Trail

Every kilometre is a real pleasure. Through Valbella and up to Piz Terza, immerse yourself in fragrant larch forests and on varied trails to the crystal-clear Lai da Rims, at a brisk trot through the wild and romantic Val Mora.

One trail – five stages

The Biosfera Trail is perfect for runners who enjoy varied trails in a spectacular natural landscape. Beautiful panoramas, exciting daily stages, cosy hotels in picturesque villages and delicious regional food round off this sporty and enjoyable experience perfectly. The circular trail comprises a total of five stages. The number of stages can be freely selected and each stage is available in an easier (il sportiv) or tougher (il dür) version. The start and end points of all stages can be reached by public transport (free of charge from the first overnight stay in Val Müstair) and the valley is very clearly laid out. You can easily make an accommodation in any village your base and tackle the various stages from there.
