Observe trails: Stay on trails to prevent erosion as well as to avoid poison oak, stinging nettles and ticks. Do not shortcut on switchbacks.

Observe trail closures: Please observe all trail closures and barriers. Trails are closed for a variety of reasons, such as for visitor safety, to protect endangered species, to prevent erosion, and/or to allow new sections of trail to harden. Visitors who disregard trail closures may endanger themselves and any potential rescuers, harm threatened and endangered species, exacerbate erosion, or prevent new sections of trail from properly hardening, which results in the degradation of the trail surface, which in turn may require the closing of the trail for repair. Thank you for your cooperation.

Caution along cliffs: Stay away from cliff edges. Loose soil can give way suddenly and you may fall. Do not climb cliffs.

Clothing: Dress appropriately. Wear layered clothing and be prepared for changing conditions.

Food & water: Always carry food and water for longer hikes. Dehydration is a common cause of exhaustion, fatigue and headaches. Raccoons and other animals can quickly find and ransack unattended food and daypacks.

Drinking water: The protozoan Giardia lamblia may be present in natural sources of water and can cause severe illness. Do not drink water from streams and all other natural sources without treating. Water may be treated by boiling, filtering, or using iodine or other chemical water purifiers. Potable drinking water is available at visitor centers and in campgrounds.

Horses: If horses are passing on the trail, step to the downhill side and greet the rider so the horse knows you are there; do not touch the animals.

Trail information: There may be trail closures in effect. Please check at the visitor center before heading out on the trails.
