Auburn to Quincy Road Trip: Sierra Secrets Unveiled

The journey from Auburn to Quincy along CA-49 and CA-70 spans roughly 85 miles, but this deceptively short route through the Sierra Nevada foothills demands a full day to savor. The highway crosses the historic Gold Country and ascends over 3,000 feet in elevation, passing through the Feather River Canyon—a geological marvel carved by the North Fork Feather River. Drivers often pull over at the Plumas County line, where a unique bridge structure spans the canyon, offering panoramic views that hint at the dense forests ahead.

This guide breaks down every aspect of the drive, from road quality to culinary stops, ensuring you know exactly how long to drive Auburn to Quincy and whether it's worth driving Auburn to Quincy.

The route crosses the Sierra Nevada, starting in oak woodlands and climbing into coniferous forests. The Feather River Canyon section from Twain to Pulga is the highlight: sheer granite walls, the river below, and the 1909 Feather River Highway (now CA-70) hugging the cliffs. Watch for the Pulga Bridge, a historic truss bridge that runs traffic over the North Fork.

In Downieville, the Yuba River offers swimming holes accessible via short hikes. The town itself (population 272) is a Gold Rush relic with a single saloon and a museum. For a cultural detour, visit the Plumas-Eureka State Park near Graeagle (15 miles from Quincy), where you can tour a stamp mill and learn about mining.

• Gold Country: Nevada City's preserved downtown (antique shops, theaters) is 12 miles from Auburn.
• Feather River Canyon: Pullouts at historic Cantara Loop (railroad trestle) and Lookout Point.
• Quincy: Plumas County Museum and the Courthouse (1890s).
• Hidden Gem: The ghost town of Seneca (off CA-70 near Chilcoot) features remnants of a 19th-century mining camp.

Best stops Auburn to Quincy include the historic Yuba Pass viewpoint and the B&B complex at Johnsville (site of the first ski lift in California).

Road quality is generally good, but winter (Nov–April) requires chains near Yuba Pass (elevation 5,100 ft). Frequent fog in the valleys (especially Yuba River area) slows visibility. The road lacks guardrails on some canyon curves; stay at or below posted speeds (35–45 mph).

Families will enjoy the Sierra Valley wetlands (30 miles of flat road between Sattley and Vinton), where you can spot sandhill cranes. Stop at the Chilcoot General Store (mile marker 20) for homemade fudge and a restroom break. Pet-friendly stops: the riparian trail in Downieville (leashed dogs allowed) and the lawn at Quincy's Town Park.

• Rest Zones: Pullouts at Table Rock (mile 15 on CA-70), Sloat (rest area with picnic tables)
• Fatigue Management: Alternate drivers every 45 minutes; stretch legs at Graeagle (golf course village)
• Emergency Services: No hospitals along route except Quincy (Plumas District Hospital). For minor issues, Downieville has a small clinic.

Things to do between Auburn and Quincy include visiting the Little Golden Treasure Mine tour in Grass Valley (kids love it) and the Feather River Nature Center near Twain.

The route begins in Auburn at the intersection of CA-49 and I-80, heading north. CA-49 winds through Grass Valley and Nevada City before joining CA-70 at the town of Marysville (though Marysville is a detour; the correct junction is CA-49/CA-70 eastbound near Yuba Pass). In reality, from Auburn, take CA-49 north to CA-20 east, then CA-70 north. The most common path is to follow CA-49 to CA-20 east (at Grass Valley), then CA-70 north at the junction near Yuba Pass.

Gas stations are sporadic: fill up in Auburn (several stations) or Grass Valley. After that, the next reliable fuel is in Downieville (34 miles from Grass Valley) or Portola (20 miles from Quincy). On CA-70, there's a Chevron in Cromberg (mile marker 10). Plan for $4.20–$4.60 per gallon in the foothills, slightly cheaper than Quincy.
