Some roadside stops are easy to pass. Frostop Drive-In in Ashton is not one of them.

Parked right on Highway 20 about 50 minutes north of Xhale. This retro drive-in has been serving cold root beer and honest American food for decades. It sits at a natural pause point on the drive toward Yellowstone or Mesa Falls, and once you've pulled in, you'll understand why regulars don't skip it.

What to Order

The menu is straightforward: classic burgers, crinkle fries, onion rings, and milkshakes. The Bacon Blue Frostop Burger has a loyal following, and the huckleberry milkshake is worth ordering on its own. But the thing Frostop is actually known for is the root beer which is served fountain-fresh in frosted mugs, creamy and smooth with a thick foamy head.

If it's your first time, order the root beer float. House-made root beer, vanilla ice cream, a frosted glass. It's the clearest reason this place has been around since 1926 and the simplest way to understand what all the fuss is about.

How Long to Budget

Give it 30 to 45 minutes. Most people treat it like a gas station stop — grab a drink and keep moving. That's the wrong approach. Sit in your car or at one of the outdoor tables, order food alongside your float, and let the place slow you down for a few minutes. That's the whole point of it.

Practical Details

  • Hours: Daily 10:00 AM – 7:00 PM (seasonal — call ahead to confirm: (208) 652-7762)
  • Service: Drive-in stalls, takeout, and outdoor seating
  • Parking note: The drive-in stalls run narrow — larger vehicles are easier to park in the main lot

Where It Fits in Your Day

Frostop lands right in the middle of the most-traveled stretch of Highway 20 between Xhale and Yellowstone. It works naturally as a fuel stop on the way up to the park, a lunch break on the way to Mesa Falls, or an easy reward on the drive home after a full day outdoors. A cold float and a hot burger after hiking beats anything from a gas station cooler by a wide margin.
