Before you go
Length, time and ascent follow the department’s description (route no. 30, yellow waymarks).
The department warns that the stretch along the Siagne can be difficult when the river is high. Do not linger under the weakened viaduct pier.
EDF works operate on the Siagne: the water can rise at any moment. Do not go down into the riverbed.
Hunting season runs from September to December, so wear bright clothing.
From mid-June to mid-September, access to the forests of the Alpes-Maritimes depends on the daily fire risk map by commune: risque-prevention-incendie.fr/alpes-maritimes. On a “red” day, entering the forest is banned.
