Come enjoy an early morning hike in Fremont Canyon Nature Preserve, part of OC Parks’ Irvine Ranch Open Space. Our hike climbs steeply from the mouth of Fremont Canyon, past an abandoned coal mine up to the Fremont Weather Station where winds have been clocked at up to 100 mph. After enjoying the view, we’ll hike back the same way to our starting point. This hike involves steep hills and a 1200’ elevation change but the rewards are panoramic views of Orange County, the Santa Ana Mountains and surrounding areas as well as possible wildlife sightings. Please arrive 15 minutes early; the entrance gate will be shut and locked 5 minutes before start of the activity. Be sure to come prepared with a sturdy day pack, water, snacks, closed-toe hiking shoes or boots, sunscreen, first aid, and all other supplies to keep you safe and healthy on the trail.

Thinking the cardio hikes might be too fast for you? If so, join us in beautiful Weir Canyon for this slightly slower introduction to cardio hiking. Along the trail, you’ll pass through coastal sage scrub, grasslands, and oak woodlands where deer and bobcats are frequently observed. Multiple steep climbs and descents, and sweeping views, are included throughout this 6-mile hike. Please make sure you are in excellent physical condition! Even though this is a slower cardio hike, it is faster than a walk. You must be able to hike 3+ miles per hour the entire time without stopping.

If you are new to mountain biking and interested in getting started the right way, or if you just want to hone your existing skills developing terrain-influenced bike handling over several types of man-made features, this is the clinic for you! The class begins with a brief overview of rider fundamentals starting with platform position and weight transfer then covering equipment basics & setup, braking, gearing and a brief bike maintenance Q&A session followed by a series of exercises demonstrating terrain-influenced bike handling over a variety of man-made features including log piles, rock step-ups, A-frames and many more. These riding techniques will be taught and practiced at the Mountain Bike Skills Development area. This activity originates in the City of Irvine and travels into OC Parks’ Irvine Ranch Open Space.
