Access. Nelson Rocks used to operate under the name Nelson Rocks Preserve, which was ran by the Hammett's until a few years ago, upon which time it was bought by Camp Horizons in Harrisonburg Virginia. Therefore, as of right now, until access issues are figured out, Nelson Rocks Outdoor center, is technically closed to unguided climbing, currently we are working out access issues for the area, and i will update them as i am informed.
