June 26, 2025, Monrovia Hillside Wilderness Preserve

Mostly smooth fire road through Monrovia Hillside Wilderness, but with some steep and technical sections that might challenge beginners. Ride counterclockwise from Canyon Park and follow the signs—many side trails cross private land. The descent includes tight switchbacks and a short singletrack section. You can stick to the main road or take the “advanced” trail, Cactus Road, for more climbs, exposure, and a fun technical finish.

Leafy park with lawns and shaded seating, restrooms, drinking water fountains, and a bike repair station. Great for a break or as trailhead to ride west along the dedicated Duarte Bike Trail, a multi-purpose trail that was founded in 1977. It stretches 1.6 miles from Royal Oaks Park at Vineyard Avenue to Buena Vista Avenue. Next to the paved cycling path runs a dirt jogging and equestrian trail shaded by oak trees. The gently sloped trail follows the historic Pacific Electric Railway route, passing an arched bridge that once carried Red Trolley Cars to Los Angeles.
