Come enjoy an early morning hike in Fremont Canyon Nature Preserve, part of OC Parks’ Irvine Ranch Open Space.

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.

The cache is titled “The Sinks- Irvine Ranch Wildlands, GC1ZB6V.” This hike is open to existing geocachers, those curious about geocaching and non-geocachers alike. There will be as much time as needed spent at The Sinks so all geocachers can record their data and make their observations to confidently log their visit to this cache site.

If you are new to mountain biking and interested in getting started the right way, or if you are an intermediate rider wanting to broaden your existing bike skills, this is the clinic for you!

Class begins with an overview of rider fundamentals: Balance, Body Position, and Wheel Placement. You will learn which is your “Chocolate Foot,” why the mantra ‘Heavy Feet / Light Hands” is essential, and how to “Fly Your Head Like a Cheetah.” Theory will always be followed by a cycle of demonstration, practice and feedback. Difficulty will be tuned for individual participants with levels for Beginner, Experienced, and Challenge. These riding techniques will be taught and practiced at the Mountain Bike Skills Development area.
