Early Morning Fitness Hike on Hicks Haul Road: 6-miles

Hiking & Fitness
Early Morning Fitness Hike on Hicks Haul Road: 6-miles

Join us for an exhilarating morning fitness hike on the paved Hicks Haul Road. This hike is a 6-mile route as a group – which is conducted at the speed of about 3.0 to 3.5 miles per hour.

The group may spread out for social distance reasons but generally will remain together for the entire hike.

The footing on the asphalt paved road is smoother than dirt roads and single-track trails normally found in Limestone Preserve but is beginning to show its age with cracks, crevices, and an occasional dip. Otherwise, the terrain is smooth, so this is a great hike for anyone who wants a “wilderness experience” without getting dirty! We will have two fairly steep hill ascents and descents. Along the way, you will have sweeping views of much of Orange County and the Santa Ana Mountains. Various animals, like hawks, deer, and lizards are also frequently seen in this area.

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

  • Each individual adult must bring with them a signed liability waiver. Minors may be added to the waiver of their respective parent or legal guardian. The form will not be available on site.
  • The waiver can be accessed and downloaded for print at home use here:  IRC Liability Waiver 2020.05
  • Be registered in advance, no walk-up registration is permitted.
  • Arrive with all necessary equipment to keep you safe on the trail, including water, proper attire, and closed-toe footwear, first aid, health needs etc.
  • Restrooms will be available, but facilities will not be sanitized for each individual.
  • You may be prevented from participating if you do not adhere to the above protocols.

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.

Reviewing the 1-through-5 Difficulty Ratings will help you evaluate your readiness to participate in this level 4 activity on the land.

Fast-Paced Fitness Hike: Hicks Haul Road

Join us every Wednesday night for a faster-paced, fitness-focused, hike on the paved Hicks Haul Road. Hikers will enjoy wonderful sunset views and a panoramic view of Orange County. This hike travels about 3.5 miles, up to the top of Loma Ridge and back down. This fitness hike is much faster than a walk and some participants may speed walk or run.

Note that this paved surface is uneven and eroded. It contains cracks and dips in the road, you may wear regular running or walking shoes. Trail shoes are fine, but not required. You must be mindful while hiking, jogging, or walking. Please bring adequate water!

UCI Loma Ridge Global Change Experiment Study Talk Series- No. 3

Special Events
UCI Loma Ridge Global Change Experiment Study Talk Series- No. 3

Irvine Ranch Conservancy is proud to host a Zoom presentation led by Nikki Fiore

We are pleased to introduce a series of talks surrounding the studies of climate change impacts from soil to landscapes, and lessons learned from the Loma Ridge Global Change Experiment. If you have hiked in the Limestone Canyon Preserve you may have seen the Loma Ridge Experiment site high above East Loma Ridge. Join us to learn more about what research takes place at the research site. Later in the series, learn more about upcoming hikes to tour the site.  

This third presentation in a series of four talks will be presented by Nikki Fiore, Ph.D. Candidate regarding soil properties on the annual grassland & coastal sage scrub boundary. She conducts studies at the UCI Loma Ridge Global Change Experiment Study Center site.

Soils are formed through the interaction of five state factors: climate, organisms, relief, parent material, and time. Any combination of these factors lead to the creation of a totally unique soil. My research uses the annual grassland/ coastal sage scrub boundary at Loma Ridge to examine how vegetation type (grass versus shrub) impacts soil properties when all other state factors are held constant. 

We are excited to share these discoveries and complex interactions with you. After registering for this activity you will receive a Zoom link before this event date and time. Thank you for your support of the Irvine Ranch Landmarks.
