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 OCParks’ 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.

Seasonal Science Series: Western Spadefoot Toad Habitat Enhancement
Join us for a slow-paced interpretive hike related to current IRC projects focused on research, monitoring, and conservation. The series will rotate through the landscape based on the season and project.
The Western Spadefoot Toad (Spea hammondii) success depends on IRC’s project to protect, restore, and enhance its breeding habitat. In collaboration with United States Geological Survey, IRC staff and volunteers have been monitoring vernal pools located at Shoestring. Although these areas are sensitive habitat, we feel it’s important to highlight some of our ongoing projects that benefit some of our rarer and at-risk species. Want to learn more? Perfect! This hike will be approximately 3.5 miles out and back from the Augustine staging area along Shoestring single track up to the ponds where we will discuss the project in depth.
