Getting the Lay of the Land

Jefferson to ThielsenThe headings lower down on this page provide quick information for each wilderness. More generally, the best place to go for wilderness information is www.wilderness.net. wilderness.net is an interagency portal covering wilderness management, research, and trip planning. There is a lot of cool stuff there. But since you have arrived on our trip planning page, we think probably what you're most interested in is their interactive map of all of the wildernesses in the United States. Each wilderness has its own individual web page with general information, plus an area management tab with details on regulations specific to a particular wilderness.

From north to south, here are the links for the wildernesses we help steward. Check them out! They're also shown in green in the image at right, which also shows ranger districts (lavender) and non-mechanized trails (red).

Basic regulations for these wildernesses include avoiding camping or campfires within 100 feet of water, and the maximum group size is 12 people and 12 stock. In high use areas, camping is limited to designated sites and a permit issued by the Forest Service is required. These are summarized below.

There is also a middle use category where camping within 100 feet of lakes and trails is prohibited. Check the area management tab of the wilderness.net page for details.
