The Marshall Canyon Trail is in La Verne, CA, starts at Oak Mesa Park and features 1,310 feet of climbing, reaching a max elevation of 2,424 feet. Known for its oak tree cover and lush terrain, itβs often referred to as "Sherwood Forest" due to its green, shady environment. The lower section is relatively flat, with more climbing occurring deeper into the canyon. For mountain bikers, there are many variations off the main trail that can add both milage and elevation to your ride. Adding the Claremont Loop, for example, can extend the ride by 4-5 miles and 800 vertical feet. The trail and surrounding area provides a refreshing NorCal feel, with shaded trails and a creek, contrasting with the typically hot and dry surrounding hills.
