Heber City to Island Park: Scenic Route Guide

Leaving Heber City, Utah, and heading to Island Park, Idaho, means tracing the edge of the Wasatch Range and crossing the Snake River Plain—a route that’s part of the Greater Yellowstone Ecosystem. The drive covers roughly 180 miles via US-189 north through Kamas, then US-40 into Wyoming, and finally ID-47 into Island Park. You’ll pass through three mountain passes, each with a distinct character.

The watersheds on this route are a geographic curiosity: streams along the Wyoming stretch drain into the Colorado River system via the Green River, while water in Island Park flows west to the Pacific via the Snake River. This continental divide boundary is crossed silently at the ID-UT state line. Knowing this adds a subtle appreciation to the drive.

Near Soapstone, Wyoming, you’ll cross the Bear River Divide at 8,000 feet—the highest point of the drive. The river itself rises in the Uinta Mountains and flows opposite to most regional rivers, falling into the Great Salt Lake instead of the Pacific. This geological oddity makes a good photo stop.

The route passes near Oregon Trail landmarks, including Piedmont (a ghost town) and the Hams Fork Crossing. While you can’t see them directly from the highway, the interpretive signs at the Wyoming/Idaho border offer historical context.

In Paris, Idaho, the Paris Tabernacle (1860s) stands as a monument to early Mormon settlement and is open for tours in summer. Just west of Montpelier, the Bear Lake Monster lore is a quirky local selling point; locals will happily tell you about the lake’s supposed creature, and the Raspberry Shakes at Bear Lake are a regional icon.

For things to do between Heber City, UT and Island Park, ID, the Carr Hardware store in Paris has been in business since 1872, offering a step back in time among its tools and goods. In Geneva, Idaho, 10 miles off the route, a tiny post office serves as a de facto community hub, and the nearby Geneva Museum displays pioneer-era artifacts.

US-40 between Evanston and Montpelier is mostly two-lane with passing opportunities, but the 7% grades on both sides of Little Mountain demand attention. The entire route is well-maintained, but winter brings heavy snow; the division bridges near Sage Creek can be icy. In the warm months, watch for livestock crossing between Kemmerer and Cokeville.

For a lunch stop with a playground, the park in Afton (on the way via ID-89 northern option) has picnic tables and a swing set. If you’re taking my recommended route via Montpelier, the National Oregon Trail Center in Montpelier has interactive exhibits and a paved pathway for stretching.

To manage fatigue, plan to stop at the rest area near Border, Wyoming (both sides of the road, with vending machines). The Montpelier City Park is another safe spot with shaded benches and a public restroom. As for pets, Bear Lake State Park's North Beach allows leashed dogs, but the state park’s main beach does not; the Idaho portion of the route is also dog-friendly for roadside stretches.

If you’re wondering is it worth driving Heber City, UT to Island Park, ID, the route’s varied landscape and low traffic on weekdays make it worthwhile for those who photography or want to avoid the congestion of Interstate 89. For extra adventure, take the gravel road from Geneva to the Wind Cave, a 3-mile hike to a natural limestone cavity.

For a great side trip, consider detouring to the Bear Lake National Wildlife Refuge, where you can see sandhill cranes and trumpeter swans; it’s a 2-mile gravel loop. And if you want to learn more about planning such detours, this how to find the best stops and hidden gems between cities guide offers tips.

Expect about 3.5 to 4.5 hours of driving time without stops, depending on weather and roadwork. For the best stops Heber City, UT to Island Park, ID, plan an all-day excursion to fully enjoy the scenery. The most direct highways are US-40 east and US-89 north, but taking US-189 through Kamas and then US-40 via Evanston offers a more scenic alternative.
