Join us on a slow-paced hike along the back-country ridges and valleys of Limestone Canyon, part of OC Parks’ Irvine Ranch Open Space. We’ll travel on rough old ranch roads passing by woodlands of majestic oak trees and expanses of Coastal Sage Scrub. Enjoy wonderful vistas from Loma Ridge. Total round trip distance is 6 miles with an elevation gain of 1100 feet at an average moving rate of 2.0-2.5 miles per hour. Some of the hills are strenuous and we will take breaks as needed. Participants should be in good hiking condition and have previously completed a similar distance hike. Please come prepared with a backpack, plenty of water (at least 1 liter), snacks, sturdy closed-toe hiking shoes or boots, sunscreen, first aid kit, and all other supplies to keep you safe and healthy on the trail. Each hiker must carry their own water and supplies. Under-prepared participants may be denied access to the event.

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.

For Wildfire Awareness Month spend the morning learning about fire dependency, resiliency and management of the Tecate Cypress tree, as well as, helping to water and nurture newly planted Tecate Cypress trees and Coast Live Oak trees at the Fremont Staging area. Please be aware that you may be instructed to use tools for this activity such as but not limited to pliers, mallets, trowels and shovels.

Enjoy an evening hike through stunning rock formations and fragrant native plants as you listen to the sounds of nature. This hike in the Irvine Open Space Preserve is done at an easy walking pace. This out-and-back program travels 3.5 miles round trip to scenic Loma Ridge and back down. Please bring a red-tinted flashlight as the return portion of the hike may be after sunset.

Join us for an extremely challenging and strenuous hiking adventure in the scenic Fremont Canyon Wilderness Area. This 15-mile loop hike is for experienced, physically fit distance hikers. The hike is on fire/SCE dirt roads with numerous significantly steep, unrelenting climbs and descents. We hike the entire rim of Fremont Canyon, passing by an abandoned coal mine, the Fremont Weather Station and the remnants of a rare stand of Tecate cypress. Along the way we’ll have sweeping views of Orange County, the Santa Ana Mountains and surrounding mountain ranges.

Spring is in the air and birds are rejoicing! Join an experienced OC Parks Volunteer as you stroll through Santiago Oaks Regional Park searching high in the trees for our flittering friends and low in the scrubs for bouncing birds.

Monitoring, management, and removal of these plant species is an important aspect of land management and habitat restoration.

Snake chaps, gloves, and tools will be provided but please feel free to bring your own if you have them. Please wear long pants, long sleeved shirts, close toed shoes, and protective sun protection.
