Start your weekend off by exploring the Agua Chinon wash and the Sinks through this self-guided opportunity. Designated trails will be open for self-guided trail use in OC Parks’ Irvine Ranch Open Space. Trail routes vary in distance and level of difficulty with choices ranging from easy one-hour walks to a strenuous 9.5-mile trek. Whether traveling by feet or on two wheels, this exploration day is a treasure waiting to be discovered by hikers and mountain bikers alike. Visitors to the Open Space during this activity are able to hike or bike to the West and East Sinks viewing areas.

Please review our Trail Tips page and FAQ page to prepare for this challenging hiking and biking opportunity.

Patrol Laguna Niguel Regional Park for visitor service, handle shelter check-ins, ensure visitor safety, address fishing issues, and possibly respond to neighboring Aliso and Wood Canyons Wilderness Park for assistance.

If you use the Wilderness Parks for hiking, biking, photography or just relaxing, Trail Work might be right up your alley! Get up close and personal with the trails you use; you’ll see them in a whole new way. No experience necessary. This is FUN hard work. Whatever your skill level is, there is a job to do: clearing drains to get the water off the trail, pruning vegetation back to keep users on the trail, moving dirt to rebuild eroded tread, and restoring impacted areas are just some of the tasks we will accomplish. We will be using tools such as loppers, picks, shovels, and McLeod’s to improve the user experience, protect the fragile habitat and increase the sustainability of our trails. Expect to hike up to 4 miles while carrying tools.

Join us every Monday night for a fitness-focused hike on the paved Hicks Haul Road in the Irvine Open Space Preserve. During the spring, summer and fall, hikers will enjoy wonderful sunset views and a panoramic overview of Orange County. This hike travels about 3.5 miles, up to the top of Loma Ridge and back down. The hike is conducted at about 3-3.5 miles per hour, but you may travel a bit faster or slower, at a walk, run, or jog depending on your comfort level. Most participants finish the route in about 1 hour. Because of the paved surface of the road, you may wear regular running or walking shoes. Trail shoes are fine, but not required.

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.

Total round trip distance is 6 miles with an elevation gain of 1200 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.
