Hiking & Fitness
After Work Fitness Hike on Paved Hicks Haul Road

Join us every Monday night for a fitness-focused hike on the paved Hicks Haul Road. During the spring, summer and fall, hikers will enjoy wonderful sunset views and a panoramic overview of Orange County.

This hike travels about 3.5 miles, up to the top of Loma Ridge and back down. The hike is conducted at about 3-3.5 miles per hour, but you may travel a bit faster or slower, at a walk, run, or jog depending on your comfort level. Most participants finish the route in about 1 hour. Because of the paved surface of the road, you may wear regular running or walking shoes. Trail shoes are fine, but not required. Please bring adequate water!

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.

Hiking & Fitness
Distance Hike to Mini Moab: Fremont Canyon

Come along with us on this epic hike from the bottom of Fremont Canyon to the bold, sandstone outcrops marking the ridgeline locally known as “Mini Moab.” This extremely challenging out-and-back hike is for experienced, physically fit distance hikers. We climb steeply along ranch roads past an abandoned coal mine, the Fremont Weather Station, remnants of a rare stand of Tecate cypress, and Lizard Rock. Less than a mile after entering the Coal Canyon Ecological Reserve, we reach our destination. The view from Mini Moab is nothing short of spectacular! After a break for snacks and to enjoy the view, we’ll retrace our steps back to the Fremont Staging Area.

Sahara Mustard Pull at Loma Ridge

Stewardship
Sahara Mustard Pull at Loma Ridge

Sahara mustard is a nasty non-native plant that has invaded thousands of acres across Southern California and has encroached at spots on the Irvine Ranch National Natural Landmarks. Now is the time to act to keep this highly invasive plant at bay! Loma Ridge was the initial encroachment and this population has been contained and steadily reduced over the last six years through hard work performed largely by volunteers. Your help is needed to search for and remove any new mustard plants that have come up from seed. This event will include bending, kneeling and walking across slopes and uneven terrain. All training and tools will be provided. We hope you can join us!

We will be riding from the staging area to the work site in a safari type vehicle.
