Ossoue (Upper)

verified Ungraded Unknown flood risk Gavarnie, Hautes-Pyrenees

Gargantan d'Ossoue is a narrow, constricted gorge above Gavarnie, limestone walled, fed by permanent snowmelt flow that runs high early in the season.

Wetsuits are mandatory per the beta on file: the water stays very cold even once the snowmelt flow eases off in late summer. Best run late summer into early fall, after the highest meltwater has passed. Permit status is unverified; the generic placeholder note on file is not a researched rule.
