Tuesday Morning Fitness Hike on Paved Hicks Haul Road

Hiking & Fitness
Hiking & Fitness

Ready for a workout? Forget the gym for the day and head outside! Join us for an exhilarating morning fitness walk on the paved Hicks Haul Road. This hike allows you to choose between a 3, 6, or 8 mile route, all of which are conducted at the speed of about 3.0 to 3.5 miles per hour.

Reviewing the 1-through-5 Difficulty Ratings will help you evaluate your readiness to participate in this level-3/4 activity on the land.

The road is paved and the terrain is smooth, so this is a great walk 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.

Walkers should be confident in their ability to hike 3, 6, or 8 miles at a steady pace. Ages 16 and up. Low interpretation.

Intermediate Mountain Bike Ride from Irvine to Limestone Canyon

Mountain Biking

We start our ride on the paved Hicks Haul Road, the extension of Jeffrey Rd north of Portola Pkwy. As we warm up on the climb to the top of the road, we enjoy increasingly beautiful views over Irvine. We then follow Loma Ridge to the East, with fantastic vistas of Orange County, the surrounding wildlands, and even Catalina Island on clear days. From Loma Ridge we fly down into Limestone Canyon and then visit the Sinks, Orange County’s own “Grand Canyon.”

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

After a snack break on the viewing deck, we continue to the Box Springs, which provides year round water for wildlife like deer. Oak trees provide shade and acorns, which the Indians used to grind into acorn meal. We can still find traces of their work. On our way back, we ride down on Limestone Ridge, a fun singletrack that leads us towards the Augustine Staging area, enjoying views of Saddleback and Santiago Canyon. From there we will follow the Shoestring Trail to climb back up to Loma Ridge, and then coast back down on the paved Hicks Haul Road to our starting point.
