Officially known as Muir Valley Nature Preserve, Muir Valley is one of Red River Gorge's crown jewels. Originally the area was privately owned by Rick and Liz Weber, but in March 2015 the Webers gifted the land to the non-profit Friends of Muir Valley (FOMV), a 501(c)3 organization. FOMV is now 100% responsible for the ownership, in addition to funding and up-keeping the property.
The valley is home to more than 30 separate climbing walls, all open to climbers at no charge, a $15 fee is charged per car for parking to offset maintenance costs.

Some important rules must be followed to ensure future access and enjoyment by all. A complete list can be found at muirvalley.org/tabs/#pills-1 , but the most important are listed below:
