Seasonal Closures
To protect the peregrine falcon, an endangered species, the following areas of the park are closed to all use from February 1 until May 31 each year:

• The Southeast Rim Trail and a portion of the Northeast Rim Trail from the Boot Canyon/Southeast Rim junction to a point just north of Campsite NE-4.
• All Southeast Rim campsites as well as Northeast (NE) campsites 4 and 5 are closed during this period. Technical rock climbing on rock faces within ¼ mile of known peregrine eyries, as posted, will not be allowed between February 1 and May 31.

The park does not plan to close any other areas but restrictions may be modified if Peregrine behavior or nesting sites do not follow traditional trends.
