Park permits allow the National Park Service to monitor and manage various Yosemite resources. In addition to
wilderness permits, for overnight backpacking in Yosemite's wilderness areas, park permits may also be required for commercial filming, bus tours, and guiding, as well as scattering cremated remains, research and collection, and weddings. For a more information and a list of Yosemite permits, visit the
NPS site.
