Come experience Limestone Canyon’s beauty from the back of your horse. Designated trails will be open for self-guided access hiking, biking, and equestrian use during Wilderness Access Day in Limestone Canyon. Equestrian riders who have trail riding experience with a fit and able horse will enjoy the historic ranch roads of days gone by. Take in the awe-inspiring vistas from the mighty ridge tops and drink in the cool canyon shade through the oak grove.

There is limited space for equestrian parking. Riders must also have the ability to transport their horse to the staging area.

Please note that you are asked to adhere to the following measures during the activity in order to participate:

  • Arrive with all necessary equipment to keep you safe on the trail, including water, proper attire, and footwear, first aid, medications, etc.
  • Restrooms will be available, but facilities will not be sanitized for each individual.

Additionally, in an effort to respect and protect all employees, volunteers, and participants, please do not sign up or attend if you are not feeling well, exhibiting any symptoms of illness or have been in recent contact with someone who was ill.

Do not stop or park anywhere along Santiago Canyon Road. The entrance gate will not open until 8am.  Anyone stopped or parked along Santiago Canyon Road prior to the opening will be subject to citation. Thank you for your cooperation with regard to the safety of everyone on the road. Please plan your drive accordingly.

Participants are required to stay on designated trails at all times. In addition to being a rare and sensitive habit, the Irvine Ranch Open Space is under strict protection. There are often unseen dangers just off-trail including, but not limited to: mountain lions, poison oak, ticks, poisonous spiders, and venomous snakes. OC Parks Rangers may issue citations for visitors found off-trail so for your safety, please stay on the designated paths during your stay in Limestone Canyon.

Other Important Notes:

  • Visiting the highly popular “The Sinks” is a 9-mile round trip hike over moderate terrain and can take the majority of the designated event time.
  • OC Park Rangers require all trails to be cleared for closure by 2:00pm.
  • No new trail users will be permitted onto the trails at least one hour prior to closing.
  • Dogs are prohibited on the Irvine Ranch Open Space. No matter how cute yours may be, 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 18 and under, must be registered by a parent or guardian.
  • Adult mountain bikers and equestrians are requested to wear helmets. Minors are required to wear helmets per state law.
  • Once registered, please email info@irconservancy.org at least 72 hours prior to the event so that we may verify whether your trailer can be accommodated in our parking configuration. Trailer parking is very limited and is subject to “first come, first served.”
  • Inclement weather or fire danger will cause the program to be cancelled.

Multi-use trail etiquette: Please Remember that bikers yield to hikers and that bikers and hikers yield to equestrians. Click here for more trail tips.

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 wildlife needs.
