The Cascadelles trail is located in the municipality of Arvrieux and is a remarkable heritage path located at 1500 m altitude, used summer and winter, therefore conducive to the diversification of activities. Alternative to the path of small happiness already funded by the ERDF, it is accessible to a wide audience. However, it has become impracticable because of the collapse of the Servier bridge allowing to cross the NANT River. the purpose of this file is therefore the financing of security and rehabilitation operations by the construction of two Himalayan footbridges (one on the Sévèr Bridge and one on the ravine of the Pavots) and a last wooden one that will be reinforced.
