Traveling to Sonora by RV

Highway 108 provides the main east-west route through Sonora, connecting directly to Modesto and the Central Valley to the west. From the north or south, Highway 49 runs right through downtown Sonora, offering easy access for RVs up to 40 feet. Both highways handle large rigs without major restrictions, though you'll want to watch for some narrower sections on Highway 49 through the historic downtown area.

If you're heading east toward Yosemite via Highway 108, be prepared for significant mountain grades starting about 20 miles east of town. The Sonora Pass route reaches over 9,600 feet elevation and isn't recommended for RVs over 25 feet or those uncomfortable with steep mountain driving. Most RVers bound for Yosemite take Highway 120 from Manteca instead.

Overnight parking options are limited in the immediate area. Walmart doesn't allow overnight parking in Sonora, and there aren't any 24-hour truck stops with designated motorhome areas. Your best bet for overnight stays involves the various campgrounds and motorhome parks scattered throughout the foothills, many of which offer full service along with service point access.

Timing matters for seasonal access too. Some forest service areas have reduced hours or limited access during winter months, so call ahead if you're traveling between November and March.
