01
Best crowd-pleasing loop
Claremont Hills Wilderness Park Loop
Claremont Foothills • Busy Foothill Loop With Wide Dirt Roads • Best After-Work Workout
A popular 5-mile loop with steady climbs, big Inland Empire views, and a social trail scene morning and evening.
If you ask locals where they hike, this loop is usually the first answer. The wide fire roads make it approachable for newer hikers, but the steady grade still delivers a solid workout. Go at sunrise or near sunset for cooler temps and the best views over Upland and the valley lights.
02
Best waterfall hike
Etiwanda Falls Trail (North Etiwanda Preserve)
North Rancho Cucamonga • Scenic Canyon Walk To A Seasonal Waterfall • Best For Waterfall Lovers
A gently climbing dirt road leads to a shaded creek and waterfall area that feels surprisingly tucked away above the suburbs.
Starting from the preserve parking lot, the trail climbs gradually through scrubby foothills before dropping into a cooler, greener canyon. The falls themselves are modest but refreshing, especially when flow is good in spring. Expect some sun exposure on the way up and weekend crowds when the weather is nice.
03
Best shady canyon ramble
Marshall Canyon Trail
La Verne Foothills • Shaded Multi-Use Canyon And Ridgeline Trail System • Best For Longer Shady Rambles
An oak-lined canyon with side trails and loops that let you tailor a quiet, mostly shaded hike just a short drive from Upland.
Marshall Canyon feels more like a classic wooded ravine than a dry foothill wash, with creek crossings, horse tracks, and birdsong under the trees. You can keep things mellow by staying low in the canyon or add mileage and views by climbing to the higher ridges. It is a great pick on warmer days when more exposed routes are baking.
04
Best quick summit challenge
Potato Mountain via Claremont Wilderness
Above Claremont Wilderness Park • Steep Summit Hike With Wide-Open City And Mountain Views • Best For Short, Steep Workouts
A punchy climb to a rounded summit known for its sweeping vistas and the tradition of decorating the summit potato.
From the trailhead off Mt. Baldy Road, the route wastes no time gaining elevation, making it a favorite for locals who want a fast but satisfying workout. The summit view takes in the Inland Empire, nearby canyons, and on clear days a long line of San Gabriel peaks. Bring water, sun protection, and a sense of humor if you decide to add your own potato to the summit shrine.
05
Best high-country escape
Icehouse Canyon Trail to Icehouse Saddle
Mt. Baldy / Angeles National Forest • High-Elevation Forest Canyon Into The Cucamonga Wilderness • Best For Experienced Hikers Seeking Alpine Feel
A classic San Gabriel trail that climbs from a creek-lined canyon into cool pine forest and big-mountain terrain above Upland.
Starting near the village of Mt. Baldy, the trail follows a lively creek past old cabin ruins before switchbacking into higher, cooler forest. The saddle offers expansive views toward Ontario and Cucamonga Peaks and down into remote side canyons. Expect a sustained climb, thinner air, and mountain weather that can change quickly, making this a rewarding choice for prepared hikers looking for a full-day outing.
