Cross the RD208 to reach the village of Viven, turning left at the town hall. Head south, crossing the RD208 again, then the bridge over the A65 towards a long gravel track leading to the wooden footbridges over the St Peyrus stream. Continue straight ahead on the tarmac road to reach the dam dyke, which you follow to reach the Argelos woods, following the signposts (the track through the meadow is private property).
