California’s gnarliest mountain drive dares you to cross a skinny lane at 8,700 feet

It’s one of the Sierra’s last quiet crossings

Most people crossing the Sierra Nevada pick a wide, fast highway and barrel through. You don’t have to.

The asphalt shrinks to a single lane with curves demanding attention. The Ebbetts Pass Scenic Byway covers 61 miles between Arnold and Markleeville along Highways 4 and 89, climbing from 4,000 feet to nearly 8,700 feet through what locals call the California Alps.

The road earned its National Scenic Byway designation in 2005, one of only seven in the state. Most Sierra passes feel like highways.

This one feels like a back road that forgot to get wider.

Silver miners paid tolls on this road in 1861

John Ebbetts surveyed this route in the 1850s, looking for a railroad crossing through the mountains. He never got one. But the pass may go back even further.

Historians believe Jedediah Smith used it in 1827 during the first recorded non-Native crossing of the Sierra. By 1861, silver miners heading to Nevada’s Comstock Lode paid tolls to use the road.

Today, it cuts through the Stanislaus and Humboldt-Toiyabe National Forests and runs along the edges of the Carson-Iceberg and Mokelumne Wilderness areas, with a state park anchoring each end.

Walk among the largest living trees on Earth

Calaveras Big Trees State Park sits at the western end of the byway and has drawn visitors since 1852, making it what historians consider the longest continuously operated tourist attraction in California.

The park holds two groves of giant sequoias. The North Grove has about 100 mature trees and a 1.5-mile loop flat enough for strollers and wheelchairs.

If you want more, the South Grove trail runs about five miles and leads to the Agassiz Tree, which stands 250 feet tall and measures more than 25 feet across.

See from Mt. Diablo to Yosemite on one trail

Arnold sits right at the snow line on the byway’s western end, and the Arnold Rim Trail starts nearby. The trail system stretches 17 miles and welcomes hikers, mountain bikers, and horseback riders.

On clear days, you can see from Mt. Diablo in the San Francisco Bay Area all the way to Mt.Lyell near Yosemite.

Cougar Rock and a viewpoint called Top of the World are two of the highlights. The first section is paved, so you can bring along anyone who needs a smooth path.

Glaciers left giant boulders balanced on the roadside

Pull over at Hell’s Kitchen Vista, and you walk straight into a field of glacial erratics, huge boulders that ancient ice flows dropped here thousands of years ago.

Balancing Rock is the one everybody notices.

Travelers on the Emigrant Trail wrote about it back in the 1800s. A short path winds through the boulders, and you’ll see rock climbers working the faces.

Interpretive panels explain the eagles and hawks that hunt the area. Just east on the road, keep an eye out for Whale Rock, one of three character rocks along the pass.

A trout-stocked lake at 7350 feet in a granite bowl

Lake Alpine fills a granite basin at 7,350 feet, ringed by red fir and lodgepole pine. The lake covers 180 surface acres and gets regularly stocked with rainbow trout, so bring your rod.

A four-mile trail loops the water, with about two miles paved and wheelchair accessible. You can swim, kayak, canoe, or just spread out a picnic on the shore.

If you want a climb, a side trail heads up to Inspiration Point, a rocky overlook above the lake that adds about 1.8 miles and 600 feet of elevation.

This alpine village hosts a two-week music festival

Bear Valley sits at about 7,100 feet and works as a base camp for the high country. You’ll find lodging, a general store, a post office, and a small museum in town.

Every late July and early August, the Bear Valley Music Festival brings two weeks of classical and contemporary performances to the mountain.

Come winter, Bear Valley Mountain Resort opens more than 1,200 acres of skiing and snowboarding. The cross-country trail system covers about 3,000 acres with 35 trails for Nordic skiing and snowshoeing.

Wildflowers and bedrock mortars in the high meadows

Stanislaus Meadow opens up along the headwaters of the Stanislaus River, and in late spring, wildflowers flood the ground. You’ll see mule’s ears, scarlet gilia, Indian paintbrush, and blue flax spread across the grass.

Trails from the meadow lead into the Carson-Iceberg Wilderness and out to Bull Run Lake. A few miles on, Hermit Valley centers on the Mokelumne River with dispersed camping and more wildflowers.

Look for bedrock mortars carved into the granite here, left by MiWuk and Washoe people who traveled through for thousands of years.

Twin lakes feed two different river systems at 8600 feet

The summit of Ebbetts Pass hits 8,736 feet and carries a California Historical Landmark marker. From up here, you look west to the Folger Peak ridge and east down into Silver Creek canyon.

About a mile west of the summit, a dirt road leads to Highland Lakes, a pair of alpine lakes sitting at 8,600 feet.

What makes them unusual is that one feeds into the Mokelumne River and the other into the Stanislaus, two completely different watersheds from the same high basin.

Late summer fills the meadows around the lakes with wildflowers.

Hikers leave oranges at this trailhead around July 4th

The 2,650-mile Pacific Crest Trail crosses Highway 4 just east of Ebbetts Pass. You don’t need to be a long-distance hiker to use it.

Head north about three miles to reach Upper Kinney Lake, passing smaller Sherrold Lake on the way. Go south to enter the Carson-Iceberg Wilderness, climbing four miles to Noble Lake with views of Noble Canyon and Highland Peak.

Around the Fourth of July, through-hikers pass through, and trail angels leave oranges and notes of encouragement at the trailhead.

A parking lot and restroom sit at the south trailhead.

Soak in 104-degree mineral springs below 10,000-foot peaks

Grover Hot Springs State Park anchors the eastern end of the byway at 5,900 feet in an alpine meadow with peaks above 10,000 feet on all sides.

Six mineral springs feed the hot pool, kept between 102 and 104 degrees, with a cool swimming pool right next to it. The park also has a 76-site campground, picnic areas, hiking trails, and a trout creek.

Nearby Markleeville is the county seat of Alpine County, California’s least-populated county, with about 1,200 residents across 743 square miles.

Every year, the town hosts the Death Ride, a 129-mile cycling challenge that climbs more than 15,000 feet over five mountain passes.

Nearly all the land you see from the road is yours

Two wilderness areas flank the byway.

The Carson-Iceberg Wilderness covers about 161,000 acres and straddles the Sierra crest between Ebbetts Pass and Sonora Pass, with peaks above 10,000 feet, broad river valleys, granite slopes, and meadows.

The Pacific Crest Trail alone runs more than 26 miles through it. To the north, the Mokelumne Wilderness protects the headwaters of the Mokelumne River.

About 96 percent of Alpine County is federal land, so nearly everything visible from the road is public and permanently protected.

Drive the Ebbetts Pass Scenic Byway in California

You pick up the byway in Arnold on Highway 4 and finish at Markleeville, where Highway 4 meets Highway 89. Without stops, the 61 miles take about two hours.

With stops, give yourself five.

The upper portions of Highway 4 close in winter, typically November through May, so check Caltrans road conditions before you go. Weather shifts fast at these elevations.

Stockton sits about 90 minutes from Arnold on the west side, and South Lake Tahoe is about an hour from Markleeville on the east.
