The top steep canyon trails near Walnut range from the moderate 1.8-mile Steep Canyon Loop in Diamond Bar to the challenging 3.3-mile Eagle Scout Trail, offering options for every fitness level and time commitment.
1. Steep Canyon Trail (Diamond Bar)
The signature Steep Canyon Trail is a 1.8-mile loop located just 3.7 miles from the 57 freeway in Diamond Bar, making it one of the most accessible steep canyon hikes in the region. This moderate trail climbs over a ridge with 426 feet of elevation gain and can be completed in under an hour. The route features informational displays about the surrounding landscape and connects with the Grandview Trail for those seeking a longer adventure. Most of the elevation gain happens early on the ascent, rewarding hikers with ridge-top views before a gentler descent through oak forest.
2. Steep Canyon–Grandview Loop (Diamond Bar)
For hikers wanting to extend their experience, the combined Steep Canyon–Grandview Loop offers a more substantial outing while remaining accessible. This loop connects the two trails and takes approximately 1.5 to 2 hours to complete. The route climbs steeply to a ridge, then descends through a shaded oak forest on the return, providing excellent shade and a variety of scenery. The loop is heavily signposted and offers unique geological and botanical features throughout, making it ideal for hikers who want more distance without extreme technical difficulty.
3. Eagle Scout Trail (Walnut Area)
The Eagle Scout Trail is a 3.3-mile out-and-back trail with 872 feet of elevation gain, offering a more challenging option for experienced hikers. This trail takes approximately 2 to 2.5 hours to complete and rewards effort with expansive views of the surrounding foothills. The sustained elevation gain makes this a solid cardiovascular workout, and the trail is popular year-round. This is an excellent choice for hikers building endurance or those seeking a half-day adventure with real elevation challenge.
4. Sycamore Canyon Park Trail (Diamond Bar)
Sycamore Canyon Park offers a 1.6-mile round-trip nature walk through walnut woodlands and riparian habitat. While shorter than other options on this list, the trail features grades up to 10% and provides an intimate look at the region’s native plant communities. The trail is well-maintained and offers a quieter alternative to busier routes, making it ideal for birdwatching and nature photography. Rest areas with picnic tables are available throughout the Walnut trail system, perfect for a post-hike meal.
5. Marshall Canyon Trail (La Verne)
Marshall Canyon Trail is a 7.8-mile segment (part of a longer 15.8-mile system) that begins in Frank G. Bonelli Regional Park and travels through La Verne into the foothills above the city. The southern portion is mostly flat and urban, while the northern section climbs into natural foothill terrain with 1,352 feet of elevation gain over the full route. This trail offers picturesque views of the surrounding landscape and excellent wildlife sightings. Hikers can choose their distance and turn-around point, making it flexible for various fitness levels. Trailheads are open sunrise to sunset, with extended hours during warmer months (8 a.m. to 7:30 p.m. March–October).
