Photo Journey Limestone Canyon: The Sinks, Loma Ridge Backcountry and Sunset

Join us in the back-country wilderness for a journey filled with beautiful sights that are photographic and artistic sketching opportunities. Our journey begins in the afternoon. We will be deep in a secluded canyon, where time is measured in centuries, even millennia, in the sandstone cliffs of this ancient place called Limestone Canyon. You will board a 4-wheel drive vehicle for a 13-mile tour of the canyon and hills surrounding it. We will stop frequently for 15-30 minutes to admire the views, take photos, sketch landscapes, and answer questions.
Twilight Fitness Hike in Limestone Canyon

Limestone Canyon is a treasure waiting to be discovered. Join us for an afternoon, fast paced, 5.5-mile fitness hike with 750 ft of elevation. The hike will be a great introduction to fitness, cardio-style hikes as well as OC Parks’ magnificent Irvine Ranch Open Space. Views of Limestone Canyon, and the surrounding wilderness, from Limestone Ridge will be the highlight of our tour.
Twilight Hike in Orchard Hills

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.

Slow Paced Hike Exploring Spring Wildflowers in Bloom

Join us for a slow-paced hike in Irvine Ranch Open Space, specifically Limestone Canyon. Our pace will be around 2.5 MPH for this 5.5-mile hike with an elevation gain of about 400 feet. Slowing our pace will encourage us to experience the land with all of our senses. We will be able to see, smell and hear the sounds of the Open Space! If you enjoy recording your sightings of wildflowers, please download the App called SEEK (INaturalist) prior to reaching the Augustine Staging area. We will use SEEK to identify native and non-native wildflowers. Our hike will take us along Limestone Canyon and then over to Dripping Springs. Dripping Springs is a year-round spring where we will encounter water that is expressed through the side of a vertical rock face. Due to shade and moisture, we will find that the plants in Dripping Springs are very different from the plants and flowers found in the meadow area of Limestone Canyon.
After Work Fitness Hike on Paved Hicks Haul Road

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.
