Looking for Native Animals in Your Backyard: Round Canyon

There are critters in your backyard: big ones, little ones, furry ones, ones with feathers, and ones with scales. They go about their business and pay little attention to you. In fact, they would rather not be bothered unless you were a tempting morsel of food. Round Canyon is teeming with wildlife, and waiting for you to experience the solitary bobcat, the elusive ring-tailed cat, the mighty great horned owl, and playful ground squirrels, among many others.

Understanding the 1-through-5 Difficulty Ratings system will help you evaluate your readiness to participate in this level-2 activity on the land.

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.
