Skip I-90 once and discover northern Idaho’s most rewarding 35-mile drive

What’s waiting along Highway 97’s lakeshore

Northern Idaho’s panhandle holds a two-lane road that most people blow past on Interstate 90 without a second glance.

The Lake Coeur d’Alene Scenic Byway runs 35 miles along Highway 97, tracing the eastern shore of a glacial lake so wide it takes an hour just to drive its length.

There are eagles here in winter, a rail trail in a national Hall of Fame, ponderosa pines older than the country, and a small town that fills to the brim every summer. And it all connects.

A lake carved by ice, named by fur traders

Lake Coeur d’Alene didn’t always look this way. Near the end of the last Ice Age, glacial floods and sediment dammed the Spokane River system and carved out this basin.

The result is a lake roughly 25 miles long and up to three miles wide, fed by the Coeur d’Alene and St. Joe rivers, draining out through the Spokane.

French-Canadian fur traders gave the name “Coeur d’Alene” to the Schitsu’umsh people, a Native American tribe whose name means “The Discovered People.”

They’ve lived in this region for thousands of years and maintain stewardship of the lake and surrounding land to this day.

More than 200 bald eagles descend on Wolf Lodge Bay each winter

From November through February, bald eagles move through Wolf Lodge Bay and Beauty Bay by the hundreds.

They’re here for the kokanee salmon, a species introduced to the lake in 1937 that eagles figured out during their southward migrations.

The Bureau of Land Management has tracked the eagle population at Wolf Lodge Bay since 1974, and in peak seasons, more than 200 birds have gathered in the area.

You can watch them dive for fish from Higgins Point, the Mineral Ridge Boat Ramp, or the Mineral Ridge Trailhead.

Hike 700 feet above the lake on Mineral Ridge Trail

The Mineral Ridge National Recreation Trail is a 3.3-mile loop that climbs about 700 feet above Lake Coeur d’Alene near Beauty Bay.

The Bureau of Land Management built the trail in 1963 as its first recreation site in Idaho, and it earned National Recreation Trail status in 1982.

Along the way, 22 marked interpretive stations point out local plants, animals, and forest ecology.

At the top, the lake spreads out below you in both directions, with Wolf Lodge Bay and Beauty Bay framed by tree-covered ridges. The trailhead sits about 11 miles east of Coeur d’Alene.

Beauty Bay is where you stop, get out and just look

Beauty Bay Recreation Area sits along the northeastern shore of the lake, managed by the Bureau of Land Management.

A paved 800-foot path leads to a viewing deck over the bay, and a short half-mile trail gives you more of those lake views from above the shoreline.

An additional half-mile loop winds through forest with more looks at the water.

If mountain biking interests you, the Beauty Bay Loop runs roughly 20 miles of forested singletrack nearby.

But sometimes the best thing here is the simplest one: you park, you walk to the deck, and you watch the light move across the water.

Osprey, moose, elk and bears all live along this road

The lower Coeur d’Alene River holds one of the region’s largest concentrations of nesting osprey. Idaho Fish and Game reports more than 50 pairs on the lower river and another 30 near the mouth of the St. Joe.

Researchers have studied and banded these birds for more than 35 years, following them as they migrate each winter to Mexico and Central America.

Away from the water, the forests along the byway support moose, mule deer, white-tailed deer, elk and black bear. The lake’s wetlands draw tundra swans during seasonal migrations.

Winter brings the eagles, summer belongs to the osprey.

A 73-mile paved rail trail built on a Union Pacific corridor

The Trail of the Coeur d’Alenes stretches 73 miles of smooth asphalt from Mullan, near the Montana border, to Plummer, near Washington.

It follows a former Union Pacific Railroad corridor, opened in March 2004, and the Rails to Trails Conservancy inducted it into its Hall of Fame in 2010.

The Coeur d’Alene Tribe, Union Pacific, the U.S. government and the State of Idaho built it together. Cyclists, walkers, inline skaters and wheelchair users all use it year-round.

Twenty developed trailheads and scenic waysides with picnic tables line the entire route.

Cross the lake on a 1921 railroad trestle

The Chatcolet Bridge started as a railroad trestle when Union Pacific built it in 1921. It ran as a swing trestle back then, rotating to let boats pass on the St. Joe River.

During trail construction in the early 2000s, crews raised and fixed the bridge in place, and they kept the original operator’s hut on top.

The crossing runs roughly 3,100 feet, gaining elevation as you go, so by the time you reach the far side you’re looking out over the lake and mountains in every direction.

The Harrison-to-Chatcolet Bridge stretch is the most traveled section of the whole 73-mile trail.

Harrison is a town of 300 that draws thousands on summer weekends

Harrison sits at the mouth of the Coeur d’Alene River on the eastern shore of the lake. Fewer than 300 people live here full time, but on busy summer days the town swells with cyclists and boaters.

The town was founded in the 1890s and incorporated in 1899, named for President Benjamin Harrison.

Because it sits at the lowest elevation point on the trail, it draws riders finishing long stretches from both directions.

A public beach, marina and waterfront park give you easy access to the lake for swimming, paddling or doing nothing in particular.

Heyburn State Park has been here longer than any other park in the Northwest

Congress created Heyburn State Park in 1908, making it the oldest state park in the Pacific Northwest.

President William Howard Taft signed the deed granting about 5,744 acres of land and 2,332 acres of water from the Coeur d’Alene Indian Reservation to the state.

Three lakes sit inside the park’s boundaries: Chatcolet, Benewah and Hidden. The St. Joe River winds along the eastern edge.

Some of the ponderosa pines here are more than 400 years old.

The Trail of the Coeur d’Alenes runs straight through, and a 6.2-mile Whitetail Loop trail gives hikers even more ground to cover.

Thousands of migrating birds stop over near Harrison every year

Between Harrison and Cataldo, the Coeur d’Alene River Wildlife Management Area stretches along the river, managed by Idaho Fish and Game since 1964.

The Thompson Lake segment inside the area includes wetlands, forested habitat and food plots that pull in thousands of migrating birds each season.

Tundra swans, raptors, shorebirds and waterfowl all move through during spring and fall migrations. Anderson Lake, near Harrison, runs quieter than the main lakeshore and draws birdwatchers and wildlife photographers.

The trail weaves through portions of the management area, putting you right in the middle of the habitat.

October turns the byway into a corridor of gold and crimson

When the larch, cottonwood and deciduous trees change in autumn, the byway becomes one of the most photogenic drives in Idaho.

The bright fall colors sit against deep blue water and dark evergreen forest, and the contrast runs for miles. Crowds thin out in the cooler months, so the trails and overlooks feel like yours.

By late November, the first bald eagles begin arriving at Wolf Lodge Bay, overlapping the tail end of fall color season.

The road stays open year-round, so every season brings something different to this stretch of northern Idaho lakeshore. October just happens to bring everything at once.

Drive the Lake Coeur d’Alene Scenic Byway in Idaho

You can pick up the byway at the junction of Interstate 90 and Idaho Highway 97, about 35 miles east of Spokane International Airport in Washington.

The route runs roughly 35 miles south, ending at Idaho Highway 3 near the White Pine Scenic Byway.

The road is two-lane and winding with few passing lanes, so give yourself at least 90 minutes for the drive without stops.

For current road conditions, hours at specific recreation areas and trail access information, check the official website for the Idaho Department of Transportation or the Bureau of Land Management.
