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 in OCParks’ Irvine Ranch Open Space. 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 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 hike for anyone who wants a “wilderness experience” without getting dirty! We will have two fairly steep 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.

Nighttime Bugs: Augustine Staging Area in Limestone Canyon

Join us for this evening program in OCParks’ Irvine Ranch Open Space, as we explore biodiversity at the local level with that most diverse group of organisms, the insects! Taking advantage of the fact that UV light is highly visible to most insects, we will attract them by using black-lights (low energy/low frequency UV lights). We can then examine them up close, record the different types (and their numbers). Don’t forget your camera as you’ll see creatures that are normally buzzing around, but not highly visible. You will be able to help us document what we find.
