And many of these hiking trails pass through numerous small quaint villages and hamlets where spectacular vistas and the grandeur of un-spoilt nature compete with old world architecture seemingly frozen in time. There is a particularly important heritage trail that leads from Zernez via Susch, Lavin, Guarda, Ardez towards Scuol and Martina, passing many significant historic sites on the way. Lavin is also the base for hiking in the spectacular Swiss National Park, Switzerland’s largest nature reserve which has a pristine landscape and animal world (Golden Eagle, Marmot, Chamois, Elk etc), making it into a unique hiking and wildlife-watching region.The excellent and super efficient Swiss transportation system (railway, post buses, cable cars etc) operates through the valley, providing easy access to hundreds of walking, hiking, trekking and cycling trails.
