Monrovia Canyon Truck Trail aka Monrovia Canyon Road aka Sawpit Canyon Fire Road has great views of the Sawpit Dam and canyon. Overall, it's an easy fire road ride that leaves you exposed to the sun. It's a relaxing downhill if you're coming from the top.
Gate restricting vehicles up the trail, easy to ride around, at the Overturf Junction.
