Traveling to Raynolds Pass by RV

Highway 20 provides the main access to Raynolds Pass, connecting West Yellowstone, Montana with Island Park, Idaho.

The nearest significant services sit about 20 miles east in West Yellowstone or 30 miles west in Island Park.

Chain requirements can pop up during severe weather, so check road conditions before heading over the pass.

Overnight parking options are limited in the immediate area. The rest area itself doesn't allow overnight stays, but dispersed camping opportunities exist on nearby Forest Service roads for those comfortable with boondocking. Most RVers use this as a through route rather than a destination stop.

Explore the Raynolds Pass Area

Fuel up before crossing the pass – the nearest gas stations are back in West Yellowstone or ahead in Island Park. Stock up on groceries and supplies in those towns too, since you won't find much between them. The elevation here means cooler temperatures even in summer, so don't be surprised if it's 15-20 degrees colder than the valleys below.

Cell service can be spotty on the pass itself, though it improves once you reach either side. If you're towing a car, test your brakes before the descent – the grades aren't extreme but they're long enough to heat up brake systems on heavy rigs.
