Attention, in order to protect endangered fauna, access to the chalky peaks in the commune of Haute-Isle is prohibited every year from March 1 to June 30 by prefectural decree. The paths to mass in Chantemesle are therefore cut off. In addition, following a collapse this summer, the Piton du Colombier is prohibited for obvious safety reasons until the end of the securing work.
