01
Steep local classic
Training Hill Trail
South Of Newcastle Near Cool • Leg-Burning Foothill Climb With Big Canyon Views • Best For A Serious Workout
A relentlessly steep climb from the American River that rewards strong legs with wide-open views over the canyon and surrounding foothills.
Locals treat Training Hill as their go-to conditioning route, thanks to sustained grades that start right out of the parking area and barely let up. Expect exposed sections, loose bits, and plenty of switchbacks, so an early start and good shoes make a big difference. On clear days, the payoff is a sweeping look back toward the river and the patchwork of ranchland around Newcastle.

Best mellow river walk
Quarry Trail, Auburn State Recreation Area
American River Canyon Near Auburn • Riverside Rail-Grade Path Through A Rugged Canyon • Relaxed Half-Day Outing
Following an old rail bed along the Middle Fork, this mostly gentle trail pairs easy walking with canyon walls, river views, and old mining history.
The Quarry Trail is a good choice when you want scenery without brutal climbing, as it follows a gradual grade beside the river with occasional side paths to explore. You’ll pass old limestone workings, tunnels, and rock walls that hint at the area’s mining past while the river runs below. In warmer weather, hikers often time this route for cooler mornings and bring plenty of water, since parts of the canyon can feel hot and reflective.
03
Most versatile trail network
Hidden Falls Regional Park
West Of Newcastle In The Foothills • Oak Woodland And Creek Canyon Network With Waterfalls • Best For Varied Mileage
A well-marked maze of loops through oak-studded hillsides and shady creek bottoms, anchored by several viewpoints of the park’s namesake falls.
Hidden Falls offers short family strolls and longer figure-eight loops, so you can tailor the distance to your group and the weather. Trails roll through open ranchland, dip into cooler creek corridors, and converge at overlooks where you can watch the water spill through the rocks. Parking reservations are often required on busy days, so locals tend to plan ahead, then linger to make the most of the drive out.
04
Water-focused favorite
Clementine Trail to Lake Clementine
North Of Auburn Along The North Fork • River And Lakeside Canyon Trail With Bridge And Dam Views • Scenic Water-Centric Route
This popular out-and-back climbs gently above the North Fork before ending near Lake Clementine, offering river, bridge, and dam views along the way.
Starting near the confluence, the trail works its way up-canyon with steady but manageable grades and frequent glimpses of the turquoise river below. The route offers a mix of shade and sun, with standout views of the Foresthill Bridge and, further on, the lake and dam. It is a busy local favorite, so early starts or weekday visits help keep the experience more relaxed.
05
Classic foothill loop
Olmstead Loop Trail
Cool, Across The Canyon From Auburn • Open Meadow And Oak Savanna Loop With Rolling Terrain • Best For Shoulder Seasons
A broad loop through grazing land and scattered oaks that trades big climbs for long views, seasonal wildflowers, and a spacious foothill feel.
Olmstead Loop has a more open, pastoral vibe than the tight river canyons, with doubletrack and singletrack winding through grasslands, rocky outcrops, and pockets of woodland. The gentle ups and downs add up over the miles but rarely feel punishing, making it a good choice for steady, conversational hiking. Many locals favor it in spring for flowers and green hills, or in fall when the heat backs off and the light gets soft.
