Livingston to Pocatello Road Trip: Montana to Idaho Guide

This route traces the Yellowstone River south on US-89 through Paradise Valley, then follows I-15 south from Butte. The 330-mile drive takes about 5.5 hours without stops.

• Key highways: US-89 south from Livingston to I-90 west, then I-15 south to Pocatello.
• Notable junction: I-90/I-15 interchange near Butte (mile marker 125).
• Historical note: The route passes through the path of the 1959 Hebgen Lake earthquake, which reshaped the Madison River canyon.

Driving fatigue is a risk on long I-15 stretches. Plan stops every 2 hours. Rest areas at mile markers 102 (Butte), 44 (Spencer), and 22 (Rigby).

Natural attractions are family-friendly: Yellowstone National Park (West Entrance 90 mins from Livingston), Grizzly & Wolf Discovery Center in West Yellowstone.

Pet-friendly: Many rest stops have pet areas; I-15 allows pets at rest areas. Hotels: Best Western in Dillon and Comfort Inn in Idaho Falls accept pets.

• Family stop: Idaho Falls' Tautphaus Park Zoo offers a midday break.
• Hidden gem: Earthquake Lake (Hebgen Lake) viewpoint near the 1959 quake site—a quick off-route turnoff at mile marker 37 on US-287.

Road safety: I-15 has good lighting and shoulders; US-89 between Livingston and Bozeman has deer crossings. Carry a spare tire. Winter travel requires chains or snow tires.

Fatigue management: Use the Pulsar rest area (I-90 east of Butte) for naps. Coffee stops: Joe's Parkway Diner in Butte, The Royal Coffeehouse in Idaho Falls.

Fuel and rest stops are plentiful along I-15, but US-89 between Livingston and Bozeman has limited services. Plan your tank at Bozeman or Butte.

• Best stops for fuel: Bozeman (Costco, multiple stations), Butte (cheapest prices), Dillon (last stop before Idaho).
• Road quality: I-15 is well-maintained; US-89 is two-lane but paved. Watch for winter snowpack from November to April.
