Jackson WY to Pocatello ID Road Trip Guide

Jackass Mail Route once used this corridor; today US-26 and US-89 connect Jackson Hole to the Portneuf Valley. The drive covers 150 miles (2.5 hours without stops), crossing the Snake River Plain and passing the Caribou-Targhee National Forest.

This route offers a compact yet diverse landscape: alpine valleys, lava fields, and historic railroad towns. It's a practical corridor for travelers heading to the Pacific Northwest or exploring southeastern Idaho.

Unlike the tourist-packed drive from Jackson to Yellowstone, this route sees less traffic, offering a calm alternative. However, winter storms can pose challenges. For tips on discovering unexpected detours, see how to find the best stops and hidden gems between cities.

• Speed limits: 65 mph on open highways, 35 mph in towns.
• Emergency services: Limited; nearest hospital in Pocatello (Portneuf Medical Center) or Jackson (St. John's).

Family and Child Suitability

The route is child-friendly, with rest areas with playgrounds (Palisades, Lava Hot Springs). The Lava Hot Springs Olympic Swimming Complex offers a zero-depth entry pool for toddlers.

Road Conditions

US-26 and US-89 are well-maintained two-lane highways, with some four-lane sections near Pocatello. Road quality is excellent in summer; winter requires snow tires or chains due to mountain passes near Alpine and Wayan.

• Cell service: Patchy between Alpine and Soda Springs (Caribou-Targhee).
• Gas stations: Adequate in towns (Alpine, Soda Springs, McCammon), but gaps of up to 40 miles exist.
• Rest areas: Two rest stops—one near Palisades Reservoir (mile marker 50) and one near Lava Hot Springs (mile marker 100).

Gas prices are typically 5-10% higher in Jackson than in Pocatello. Filling up in Alpine or Soda Springs saves money. Average fuel cost for the trip (mid-size SUV) is around $20-25.

• Cheapest gas: Soda Springs (often 5-8 cents cheaper per gallon than surrounding areas).

National Protections and Geologic Wonders

Caribou-Targhee National Forest spans much of the route, offering hiking and fishing. A 30-minute detour to the west of Soda Springs leads to the Soda Springs Geyser, a man-made cold-water geyser that erupts every hour.
