Wear comfortable clothes and sturdy shoes and bring water for the hike.

You will enjoy a gorgeous sunset with panoramic views of Orange County while hiking in OC Parks’ Irvine Ranch Open Space on the paved Hicks Haul Road. This hike travels 6 miles, out and back crossing over Loma Ridge. This is the perfect activity for you to get your work-out in and view the sunset. The hike is conducted at an average pace of 3 miles per hour, but you may travel a bit faster or slower, at a walk, run, or jog depending on your comfort level. 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.

It’s easy to think many of the birds we see and hear look and act the same. But do they? Bring your binoculars and join us on a slow/medium paced walk in OC Parks’ Irvine Ranch Open Space, 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 start your week with us on our Super Treks in the Landmarks. Join us as we explore Weir Canyon, part of OC Parks’ Irvine Ranch Open Space.

We will return through a beautiful oak woodland. Please wear hiking shoes/boots and bring water, a trail snack, sunscreen, hat, and any other necessary equipment to keep you safe on the trail. Participants must be able to hike 9+ miles with an accumulated elevation gain of 1800 feet at an average moving rate of 3 miles per hour.

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.

Join us for a tour of the canyons enjoying the oak woodlands of Weir Canyon and the vistas of the Fremont Canyon high ridges. This hike will start at the mouth of Fremont Canyon and cross over to Weir Canyon via the hills above Irvine Regional Park. We’ll enter Weir Canyon at Rifle Range Rd and walk to the very top at the Overlook. After a quick snack break, we’ll begin the return circuit through Upper Blind Canyon gaining the upper ridges of Fremont Canyon and descending to the starting point passing an abandoned coal mine along the way. Distance is 14 miles with 2400 feet of elevation gain at an average of 3 mph – designed for advanced hikers. Periodic brief breaks are planned. Participants must be physically fit and have distance hiking experience.

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.

Please join us as we enhance habitat adjacent to the East and West viewing areas at the Sinks in Limestone Canyon. This area is characterized by beautiful geological formations that resemble a mini–Grand Canyon. Volunteers will travel for approximately 20 minutes in an open-air safari style truck to the project sites. The morning will be spent watering native shrubs and rebuilding berms. We will be using small shovels and other tools. No experience necessary.
