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.

Pulling Together at Quail Hill

Stewardship
Pulling Together at Quail Hill

North African Knapweed, Centaurea diluta, is a recently introduced invasive plant and we need your help to get rid of it! Invading weeds degrade habitat for wildlife, exacerbate wildfire risks, and reduce overall biodiversity. Help us keep wildlife healthy by weeding North African Knapweed from Quail Hill in Irvine.

This activity takes place on some uneven terrain, and sturdy hiking boots are highly recommended. Training and tools will be provided to ensure your safety and comfort. Rattlesnakes are occasionally seen here and generally avoid people, but protective gear will be provided.

We will meet at the Quail Hill Trailhead parking lot, then walk 15-20 minutes on a bikeway adjacent to the 405 Freeway to the work site.
