Moderate Paced Mountain Bike Ride: Baker and Fremont Canyons

Mountain Biking
Moderate Paced Mountain Bike Ride: Baker and Fremont Canyons

Enjoy riding in the wilderness on empty trails? Then join us on a docent-led mountain bike ride that loops through Fremont, Baker and Black Star Canyons. The route features expansive views, as well as the flora and fauna of the Fremont Canyon Nature Preserve and Black Star Canyon Nature Park. If you are very physically fit and in excellent cardio shape, this is a great opportunity to enjoy this seldom visited wilderness of Orange County!

This is a moderate-paced ride designed for the experienced beginner to intermediate rider who is in excellent cardio shape and is physically fit, but sometimes needs to move slower on steep ascents/descents. We will ride both fire roads and largely non-technical single track trails. The ride will regroup and rest as needed and an opportunity will be provided for a snack break.

Please note, the ride is approximately 15 miles long with 2300 feet of elevation gain. The route has climbs with some extended steep sections.  The climb to Cathedral Rock is a 3+ mile climb that gains 1500+ feet in altitude (average 9% gradient with a number of steeper pitches). Motorized Mountain Bikes of any class or type are not permitted.

Scatology 101 (or who's poop is this?)

Join us on a stroll through Baker Meadow as we look for animal scat. That’s right! The biproduct of the animal’s waste. Find out how this discarded material is used by animals to communicate, protect from predators and the elements, and attract mates. We will dissect an owl pellet and determine what prey is consumed by owls. And how a coprolite (fossil scat) is used by scientists to reveal essential information about the diets and environments of ancient creatures, showcasing ecological interactions and changes over time.
