About Red River Gorge — Muir Valley

Muir Valley is a 400-acre privately protected preserve in the northern Red River Gorge, with 400+ sport and trad routes across more than 30 walls of hard Corbin sandstone (20–200 feet). Cliffs face every direction, so climbers pick sectors by season — south-facing walls shine on cool days, north-facing steep bunkers stay shaded through summer. Managed by the non-profit Friends of Muir Valley; access is $15 daily parking or a $150 annual membership (includes 12-month parking pass) plus a signed waiver via muirvalley.org/waiver. No dogs (or unattended dogs in vehicles), no hammocks, park in the official lot only. Cumberland sandstone wet-rock ethic still applies — wait until dry. October, November and April are prime; midwinter climbs on warm sunny days; June–August is oppressively humid.
