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 signsβmany 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 βadvancedβ 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.

Chantrey Flats is the natural end for those riding the Sturtevant Trail. If you shuttled to Mt. Wilson with a friend then this is likely the end of the line for you. Others might need to ride back down to Altadena if they took the shuttle offered by SCOAoutdoors.net. And still others might be climbing their way back up to the top via the myriad of roads and trails that depart from this picnic area.

This telescope was built in 1917 and took over 11 years due difficulty hauling all the components up Mt. Wilson Toll Road. The glass mirror weighs around 9,000 pounds and remains the largest solid glass mirror ever made. This was the largest telescope until the 200" telescope was built on Palomar Mountain. mtwilson.edu/building-the-100-inch-telescope

Gabrielino Trail offers a short cut back to the Chantry Flats parking if you decide to not continue along the Lower Winter Creek Trail. If you come to a metal bridge crossing over a stream, you are going the right way. ,

Mt. Zion offers a great, although sometimes hazy, view of the Angeles National Forest and surrounding peaks. The trail leading up is very well shaded with just the final approach being more exposed to the sun.
