Highway 140 serves as your main artery into Mariposa, connecting seamlessly with Highway 99 and Interstate 5 from the Central Valley. The route climbs gradually from Merced through rolling foothills, gaining about 1,500 feet in elevation over 30 miles. Motorhome drivers won't encounter any serious grade concerns or tight curves on this approach, making it suitable for larger motorhomes and long trailers.

Stick to Highway 140 if you're pulling a big rig or prefer straightforward driving. The town itself sits at the intersection of these highways, so navigation stays simple once you arrive.
Overnight parking options remain limited in downtown Mariposa, with most RVers continuing to established campgrounds or heading into Yosemite. The nearest Walmart sits 30 miles west in Merced if you need supplies or overnight parking. Local businesses generally don't accommodate motorhome parking, so plan your stops accordingly.
Winter brings occasional snow to the area, though Highway 140 typically stays clear with regular maintenance. Chain requirements rarely affect the Mariposa area itself, but conditions can change quickly as you head higher into Yosemite. Check current road conditions before making the climb, especially between December and March when storms can create challenging driving situations for RVs.
