Fremont Canyon Nature Preserve, in all its beauty, is situated in the Santa Ana Mountains of Orange County. Fremont Canyon is often referred to by some as “the Yosemite of Orange County,” because of its picturesque granite rock formations, caves, ridgelines, and steep canyon walls. The peak of Fremont, situated at 2,376 ft., one can take in the breathtaking views of the snow-covered San Gabriel Mountains and as far north as Los Angeles and Palos Verdes. The one loop course will take you past many varieties of endangered plants, including coastal sage scrub, chaparral, oak woodlands, and the rare Tecate cypress. This diverse habitat of Fremont teems with wildlife, including cactus wrens, bats, Granite Spiny lizards, San Diego mountain king snakes, Bell’s sage sparrows, rock wrens, mountains lions, mule deer and golden eagles.
Come join us for the unique experience to race in Limestone Canyon. The 1 lap course is 21 miles of fire-road and single track. It has a mix of everything from technical trails, switch backs, and steep inclines and descents
Limestone Canyon offers riders the experience of seeing “original California” in its fall glory. The course will meander under a canopy of thick oaks, alongside seasonal creeks, a year-round dripping spring and past a striking geological formation known as “the Sinks.” This pristine canyon will give riders a sense of calm solitude as they race through serene meadows and rolling hills. Once on the ridge you will be captivated by panoramic views of the Pacific Ocean, Catalina Island, Irvine Lake, and the Cleveland National Forest.
OC MTB Races works as a partner with OC Parks and the Irvine Ranch Conservancy. We encourage our mountain bikers to contribute time to the land by volunteering for activities with OC Parks and The Irvine Ranch Conservancy. We also encourage our riders to adhere to all trail safety rules. Pre-riding the course is not allowed unless it occurs on wilderness access days or docent-led activities. Pre-riding the course may jeopardize our ability to offer these events.
