Mosier to Groveland Drive: Route Essentials

This route begins in Mosier, Oregon, a town that sits atop the Columbia River Gorge basalt, a remnant of Miocene-era floods that scoured the Pacific Northwest 15 million years ago. Your destination, Groveland, California, lies near the western flank of the Sierra Nevada, just 26 miles from Yosemite’s Big Oak Flat entrance. The 750-mile drive traverses the Cascade Range, the Modoc Plateau, the Sacramento Valley, and the Sierra foothills, offering a dramatic shift from lush river valleys to high desert and then to granite monoliths.

Direct driving time is approximately 11 hours and 45 minutes without stops, but the journey rewards a slower pace. You’ll cross two states (Oregon and California) and pass through the ancestral lands of the Confederated Tribes of Warm Springs, the Modoc, and the Miwuk.

The route showcases two UNESCO World Heritage Sites: Crater Lake National Park (Oregon) and Yosemite National Park (California). Crater Lake, visible as a brief detour off US-97 near Prospect, is the deepest lake in the US (1,943 ft) and formed in the caldera of Mount Mazama. Yosemite’s iconic valleys and giant sequoias are just 45 miles from Groveland via CA-120.

In between, the Modoc Plateau presents volcanic tablelands teeming with birdlife at Tule Lake National Wildlife Refuge, where you might spot bald eagles. The town of Burney offers Burney Falls, a 129-foot waterfall that President Teddy Roosevelt called the “Eighth Wonder of the World,” a worthy stop for a short hike.

Local commerce thrives in small towns: Sisters, Oregon (detour west of US-97) has a Western-themed main street with indie bookshops; in Dunsmuir, California, an old railroad town, you can grab a beer at a historic hotel. At Groveland, stop at the Iron Door Saloon, an 1852 gold-rush-era bar with a bullet-riddled tin ceiling. The local farmers market in Sonora (May–October) sells Sierra-grown apples and olive oil.

Climate shifts dramatically: Mosier sees 15 inches of rain annually, while Groveland receives 32 inches. Summer temps range from 80°F in Mosier to 95°F in the Central Valley, but nights cool to 50°F in the mountains.

Your path follows US-97 south from Mosier to Klamath Falls, then connects to CA-89 through the Modoc National Forest, and finally joins CA-120 (Tioga Road) toward Yosemite, ending at Groveland. This routing avoids the congestion of I-5 but demands careful fuel planning. Longer stretches between stations exist, especially on CA-89 between Tulelake and Burney, where services are sparse.

• Fuel stops: Mosier (last in OR), Klamath Falls, Tulelake, Burney, and Sonora (closest major town to Groveland).
• Average gas price (CA): $4.20/gal vs. OR: $3.80/gal, so fill up before entering California.
• Total fuel cost for a standard sedan (30 mpg): ~$105–$120, depending on current prices.

Road conditions are generally good, with mostly two-lane highways. Be prepared for a twisting descent on CA-120 from Tioga Pass (elevation 9,945 ft) into Groveland during summer; snow closes this pass from October to late May, so check Caltrans. If you travel in winter, you must detour via CA-49 or I-5, adding at least 2 hours.

Safety prioritizes: on two-lane roads, watch for logging trucks; on CA-89, deer are common at dawn. Emergency services are sparse between Klamath Falls and Burney—cellular coverage drops in the Modoc National Forest, so carry a paper map or offline GPS. For pet owners, many rest areas lack shade, but the Tulelake State Park offers a leash-free trail; in Groveland, several vacation rentals accept pets, and the Yosemite National Park prohibits pets on trails, so plan kennel options.

For children, the drive offers the College of the Siskiyous' dinosaur trackway in Montague, a free outdoor paleontology exhibit; in Oakdale, the “Cowboy Museum” has interactive displays. Caves at Lava Beds National Monument (near Tulelake) fascinate kids, but helmets are recommended and flashlights are mandatory.

Fatigue management is essential: rest stops on US-97 are spaced every 30 miles; the Klamath County Visitor Center in Klamath Falls has a garden and picnic area. On CA-89, pullouts near Burney Falls offer picnic tables. The state maintains safe rest areas at 20-mile intervals on CA-120, though signage is limited.

Suitable family lodging includes the historic Groveland Hotel (circa 1849) with family suites, and in Klamath Falls, the Running Y Ranch resort offers a pool and bike rentals. For a unique night, book a yurt at Crater Lake’s Lost Creek Campground (summer only).
