West Yellowstone to Alpine, WY: Ultimate Road Trip Guide

Stretching roughly 90 miles along U.S. Route 191 and U.S. Route 26/89, this drive connects two gateways to the Greater Yellowstone Ecosystem. It's a route where you can see the Continental Divide, cross the Snake River, and spot wildlife within minutes of leaving West Yellowstone.

This guide covers everything from driving times to hidden gems, ensuring you make the most of this iconic journey.

This journey passes through the John D. Rockefeller Jr. Memorial Parkway, which links Yellowstone and Grand Teton National Parks. The area is not a UNESCO World Heritage Site itself, but both adjacent parks are. Along the way, you'll encounter the Continental Divide at an elevation of 8,300 feet, where water flows either to the Pacific or Atlantic oceans.

Local commerce is limited but includes the Flagg Ranch Resort, offering lodging, groceries, and fuel. For a taste of local culture, visit the Colter Bay Visitor Center in Grand Teton, which features Native American exhibits.

The drive typically takes 2 to 2.5 hours of pure driving time, but plan for at least half a day to enjoy the scenery and stops. The route is well-paved and maintained year-round, though winter conditions can be challenging.

Fuel is available in West Yellowstone, but after that, the next reliable gas stations are in Moran and Alpine. It's wise to fill up before leaving.

• Last major cell service: West Yellowstone and a few spots along the route.
• Restrooms: Available at visitor centers and developed pullouts.
• Speed limits: 45–65 mph, slower in wildlife zones.

Wildlife, including bison and elk, frequently cross the road—especially at dawn and dusk. Drive with caution and expect sudden stops. The road is safe when you follow park speed limits and remain alert.

For families, the National Museum of Wildlife Art in Jackson, WY, is a great indoor stop, but on this route, consider a short walk at Grassy Lake Road or the Jackson Lake Overlook. Services are sparse, so pack snacks and water.

• Rest areas: Scenic pullouts at Jackson Lake and Oxbow Bend offer safe spots to stretch.
• Pet-friendly: Pets are allowed on leashes in many pullouts and picnic areas, but not on trails.
• Fatigue: Stop at the Flagg Ranch or Colter Bay for a break.

Hidden off-route spots: A short detour on Forest Road 300 leads to the Huckleberry Hot Springs, a natural thermal area; check local regulations before soaking.
