This is a natural area characterized by certain inherent dangers including: mountain lions, rattlesnakes, poisonous plants and insects, weather extremes, loose rocks and rugged terrain.

Other Important Notes:
- OC Parks Rangers require all trails to be cleared for closure by 2pm
- No new trail users will be permitted onto the trails beginning one hour prior to closing.
- Dogs are prohibited on the Irvine Ranch Open Space. By nature, dogs are predators; their presence and their lingering scent disturb the indigenous wildlife and disrupt vital routines long after a dog has left the area.
- Minors, ages 17 and under, must be accompanied by a parent or guardian.
- Adult mountain bikers are requested to wear helmets. Minors are required to wear helmets per state law.
- Inclement weather or fire danger will cause the program to be cancelled.

To minimize the human impact on wildlife and their habitat, there may be unannounced trail closures or the rotation of areas being open and closed. This is an adaptive management approach to accommodate both the human users and the wildlife needs.
