Enjoy an evening hike through stunning rock formations and fragrant native plants as you listen to the sounds of nature. This hike is done at an easy walking pace. This out-and-back program travels 2.5 miles round trip up to scenic Loma Ridge and back down.

Birds are among the most colorful and entertaining forms of wildlife on the Irvine Ranch Natural Landmarks. Bring your binoculars and join us on a slow/medium paced walk in OC Parks’ Red Rock Wilderness, as we search for resident and visiting birds of the local coastal sage scrub, oak woodland, riparian, and grassland habitats. We will discuss the diverse features of the birds we observe and how they match the season, their habitat and lifestyle. We will travel mostly on ranch roads, usually without shade. Beginners to advanced bird enthusiasts are welcome. Please wear sturdy shoes suitable for hiking and bring water, along with sun protection such as a hat and sunscreen. Bring a small birding field guide if you have one. A few binoculars will be available to borrow.

Come out and enjoy the evening with us on the Orchard Hills loop trail. This trail meanders around an avocado orchard on the edge of the open space preserve and provides fantastic ridge-top views of Irvine and the Pacific coastline.

The three-mile loop has several very steep climbs and uneven terrain. This hike is done at a moderate pace. Your effort is rewarded with a beautiful, unobstructed view to the west. This hike is not suitable for children under 12. Wear sturdy, closed-toed hiking shoes, bring water and a red LED flashlight.

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. Please bring adequate water.

Come along with us on this morning hike through beautiful Limestone Canyon Nature Preserve, part of OC Parks’ Irvine Ranch Open Space.

This hike involves steep climbs and descents on both double and single-track trails.

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.

Come and explore Newport Beach’s Buck Gully Reserve trail system. Beginning from the Oasis Senior Center, we’ll hike up through the almost 3-mile length of the canyon, then along San Joaquin Hills Road for a bit, stopping at Canyon Watch Park where we will take in the panoramic view of the reserve and the Pacific coastline before descending back into the canyon along the Bobcat Trail. Please bring water, a light trail snack, sturdy closed-toe shoes and supplies to keep you safe during the journey. Sunscreen and a hat are highly recommended. This activity is conducted at a walking pace, approximately 3 miles per hour.

Total round-trip distance is 6 miles with an elevation gain of 1000 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.

Explore Aliso and Wood Canyons Wilderness Park with OC Parks and Laguna Canyon Foundation Volunteers, where you might see deer, bobcats, and hawks.
