Wilderness.net's GIS/GPS data download options offer data obtained from the wilderness management agencies in formats intended for easy and accessible public use. Wilderness.net is in no way condoning or endorsing the application of these data for any given purpose. It is the sole responsibility of the user to determine whether or not the data are suitable for the intended purpose. It is also the obligation of the user to apply those data in an appropriate and conscientious manner. Although Wilderness.net attempts to use the most current and complete geospatial data available, accuracy varies.

If you don't have a GPS unit, you can still access wilderness data on many smartphones. Many smartphones also offer GPS capabilities.

- Google Maps and Google Earth apps: These do not mark the actual wilderness boundaries, but a name search will pinpoint one or more locations.
- Avenza app: Increasingly used by the Forest Service to provide access to PDF travel maps. Search for maps by National Forest name. Free PDF maps and for-pay maps are available through this app.
- ArcGIS app: Provides access to maps created by ESRI, other companies, and individuals on ArcGIS online.

These files (.kmz format) are for use in Google Earth. Since Google Earth often has performance issues with large files (errors have been reported to this effect), a single file containing all wilderness areas is no longer available. Instead, state-wide files have been created. All of the state files, with the exception of Alaska, California, Nevada and Washington can also be viewed using Google Maps by clicking on the view link provided. In these four cases, multiple files for each state are provided in addition to the state-wide file.
The National Wilderness Preservation System is comprised of wilderness areas managed by the Bureau of Land Management, Fish and Wildlife Service, Forest Service and National Park Service. The dataset available here was created by mining and combining the best available data from these federal agencies into a single dataset representative of the entire wilderness system. The Wilderness Institute at the University of Montana's College of Forestry and Conservation, through a unique partnership with these four agencies, maintains and serves this public dataset online in both map service and shapefile format.
Shapefiles are for use by those with GIS mapping software and expertise using and manipulating geographic data. You can download a shapefile of the entire NWPS
or select a wilderness below to download just the boundary for that area. You can also connect to our public wilderness feature service
and map service
(you may need to omit "rest" when adding from ArcGIS). Feature level metadata is available for boundaries that have been updated since 7/22/2009. This Excel spreadsheet
provides the date of last update and contact information for the person from which the data was obtained. Boundaries are generally reobtained from the managing agencies and updated within this dataset yearly.
Official Boundary Descriptions
By law, boundary descriptions of wilderness are available to the public. Boundary descriptions for all Forest Service wilderness areas
are available for download online. For wilderness areas managed by the Bureau of Land Management, Fish and Wildlife Service, and National Park Service, boundary descriptions can be obtained by contacting the managing office.
