Intro to Cardio Hike: Weir Canyon Rifle Range Loop

Hiking & Fitness
Intro to Cardio Hike: Weir Canyon Rifle Range Loop

Thinking the cardio hikes might be too fast for you? If so, join us in beautiful Weir Canyon for this slightly slower introduction to cardio hiking. Along the trail, you’ll pass through coastal sage scrub, grasslands, and oak woodlands where deer and bobcats are frequently observed. Multiple steep climbs and descents, and sweeping views, are included throughout this 6-mile hike. Please make sure you are in excellent physical condition! Even though this is a slower cardio hike, it is faster than a walk. You must be able to hike 3+ miles per hour the entire time without stopping.

Tuesday Morning Fitness Hike on Paved Hicks Haul Road

Hiking & Fitness
Tuesday Morning Fitness Hike on Paved Hicks Haul Road

Ready for a workout? Forget the gym for the day and head outside! Join us for an exhilarating morning fitness hike on the paved Hicks Haul Road in OC Parks’ Irvine Ranch Open Space. 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. The footing on the asphalt paved road is smoother than dirt roads and single track trails normally found in Limestone Canyon Nature 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 walk for anyone who wants a “wilderness experience” without getting dirty! The 6 and 8 mile routes experience two fairly steep ascents and descents. The 3 mile route takes you to the top of Loma Ridge and back down. 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.
