Yellowstone, WY → Yosemite, CA

The 844-mile journey from Yellowstone National Park to Yosemite National Park takes you through some of the American West's most dramatic landscape transitions. You'll depart Yellowstone heading south through Wyoming on US-191, then connect to US-287 south toward Idaho Falls. From there, you'll pick up I-15 heading south through Idaho and into Utah, where you'll transition to I-70 eastbound, then eventually south on US-89 as you approach the Utah-Arizona border. The final leg takes you through Nevada on US-395 north before entering California's eastern Sierra Nevada region and arriving at Yosemite's eastern entrance. This routing, covering approximately 14 hours and 9 minutes of driving time, weaves through the Great Basin and Rocky Mountain regions while gradually descending toward California's dramatic mountain ranges.

As you drive south from Yellowstone, you'll experience dramatic elevation changes that define this route. The drive begins around 7,000 feet in elevation and takes you through high mountain passes, including several sections above 8,000 feet in Utah and Nevada, before descending into the Sierra Nevada valleys. You'll cross the expansive, high-desert terrain of southern Idaho and Utah, where sagebrush-covered plateaus stretch toward distant peaks. The landscape transforms noticeably as you move from the volcanic Yellowstone region into the canyon country around Bryce Canyon and Cedar Breaks, where brilliant red rock formations punctuate the horizon.

You'll pass through or near several notable communities that break up the rural stretches, including Idaho Falls, Provo, and Cedar City in Utah. The drive includes substantial rural sections through Nevada's Great Basin, where you might drive 50+ miles without seeing services, so plan fuel stops accordingly. The final approach to Yosemite via US-395 offers some of California's most stunning scenery, with the Sierra Nevada rising dramatically to your west as you drive through the Mammoth Lakes region.

This epic drive is most enjoyable during late spring through early fall, when all mountain passes are reliably open and weather is stable. Winter driving, particularly November through March, presents significant challenges with snow-covered passes, especially in the Utah and Nevada sections, potentially adding hours to your journey or requiring route modifications.

Seasonal Driving Considerations

Mountain passes along this corridor can be treacherous from October through May, with chain requirements, road closures, and whiteout conditions at higher elevations. Summer brings its own challenges — afternoon thunderstorms are common above 7,000 feet, and construction season narrows lanes on key highways. Always check pass conditions before departing, and carry emergency supplies during the colder months.
