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, it’s 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.

Cucamonga Peak rises up to 8,862 feet and is one of the most popular peaks that you can access from the Icehouse Canyon Trail. You get an awesome view of the San Gabriel range from the peak, which you should only attempt to run up in the dry season.

Wonderful bike trail, most of which runs off-road parallel to the original Route 66 through the suburbs of Los Angeles. Very relaxed driving. Cafes, restaurants, bike shops, markets, etc. in the immediate vicinity or even directly on the trail.

The bear canyon trail is one of the best in the area, bringing you steep segments, a bit of snow, and incredible views. The first part of the trail is also special as you can hear the creek for about a mile. You might even end up crossing small streams.

Reaching the summit of Cucamonga you know you worked hard! But look around and enjoy the majestic views over the San Gabriel mountains from one of the highest peaks within the mountain range. Bring appropriate gear if you hike in winter conditions. If you hike from the Icehouse Canyon Trailhead please obtain your wilderness permit from the Angeles National Forest, Baldy Ranger Station. If you prefer ascending via Middle Fork Trail, you can obtain the permit from the San Bernardino National Forest, Lytle Creek Ranger Station.

Bear Canyon Trail—also called the Old Mt. Baldy Trail—offers some of the finest scenery and rewarding views in the San Gabriel Mountains high country. The first 1.8 miles to Bear Flat delightfully travels a superb single-track trail adorned with fern under a rich canopy of live oak, bay, and bigcone Douglas-fir. The lively creek gurgles, bubbles, splashes, and cascades down this enchanting canyon. Beyond Bear Flat the trail begins to steeply climb the chaparral-covered southeast flank of Mt. Baldy's great south ridge. You're rewarded with expanding views of Ontario Ridge, Icehouse Canyon, the "Three T's" and Baldy Notch. You'll then enter an open conifer forest with wide-reaching views toward the expansive San Gabriel Mountains to the west. Even without achieving a grand mountain summit, this hike is sure to provide a fulfilling outing for even a diehard peak bagger. http://www.simpsoncity.com/hiking/bearflat.html
