Muir Valley is a nonprofit nature preserve and rock climbing park run by climbers, for climbers. We provide an unforgettable outdoor experience through public access to world class climbing routes at all skill levels, well maintained hiking trails, and opportunities for volunteerism to give back to the community through environmental and climber safety stewardship. Located in the Red River Gorge area, Muir Valley is approximately 360 acres in size, walled in by over seven miles of majestic cliffs of hard Corbin Sandstone that range in height from 20 feet to over 200 feet. Over 400 climbs – both trad and sport – provide a spectacular experience to visitors from all over the world. Waterfalls, caves, and mountain streams add to the natural beauty. Mountain laurel, rhododendron, and many other species of wildflowers and plants grace the valley floor and hillsides.
