The Wilderness Society and National Parks
The Wilderness Society works to ensure that portions of our National Parks are preserved as federally protected wilderness, the highest level of protection afforded by the government.
These wilderness designations are important because they ensure the most pristine portions of national parks remain unblemished from industry and development for all Americans to enjoy year after year.
