Located on the largest wetland of altitude in France (the Drugeon Basin), the town of Frasne includes an area of Tourbière, classified as Regional Nature Reserve, which has been developed to allow its opening to the public. Wishing to connect the centre-bourg and the TGV station with the Tourbières site, the municipality has thus embarked on the development of several sections of soft links. The route will also be marked with explanatory panels and totems to discover the small local heritage.
