About: List of National Natural Landmarks in West Virginia

This is a list of the National Natural Landmarks (NNLs) in West Virginia. There are sixteen in all — five are wetlands (such as bogs and swamps), three are forests, six are limestone caves/karst, and two are rock formations. All are located entirely within West Virginia with the exception of the Cranesville Swamp Nature Sanctuary, which lies mostly within Garrett County, Maryland but also extends into Preston County, West Virginia. Eleven of the sixteen NNLs are within the boundaries of the Monongahela National Forest, although this does not necessarily mean they are on public land.
