By Dianne Titos | Published on 25 March 2022

A road trip from Portland to Yellowstone National Park will encompass some of the best of the American West. You can traverse the mountains like the pioneers that settled America. It might surprise you how much there is to see in Oregon, Idaho, and Wyoming.

The road trip from Portland to Yellowstone covers 950 miles and take 18 hours of driving. Along the way, stops include the cities of Boise, Twin Falls, Idaho Falls and Jackson, as well as Payette and Bridger-Teton National Forests.

Read on to find out what route is the best, where to stay along the way, and some of the best sights to see during this legendary road trip.

How far is Yellowstone from Portland and how long will the road trip take?

The 950-mile road trip from Portland to Yellowstone National Park will take you about 2 to 3 days of driving. However, if you can spare the time, I would suggest you allow yourself up to a week. This will allow you to slow down and really enjoy the journey.

This route will take you through some breathtaking scenery. You will get to see the Columbia River Gorge, Craters of the Moon National Monument, and the world famous Teton Mountains, topped off by what is arguably America's most iconic national park.

The route is mostly interstate driving, which makes it relatively fast. However, there are also some great detours that will take you off the interstate, so the driving is varied and interesting.

Traffic should not be much of an issue. The only major city on the route is Boise, so if you can avoid going through it at rush hour, then you shouldn't have any problems. Either way, the drive is relatively long, so you'll have plenty of places to stop on the way if you see traffic ahead.

From Portland, head directly east on Interstate 84 along the Columbia River Gorge. Follow the interstate as it meanders through small cities like La Grande and Baker City. At Ontario, you will cross the Snake River before heading into Nampa and Boise, a major city on the route.

Follow Interstate 84 through Boise and south to Twin Falls, where the iconic Shoshone Falls are located. Take Highway 93 north from Twin Falls before turning onto Highway 26 at Shoshone.

Highway 26 will lead you to the otherworldly Craters of the Moon National Monument and Preserve. After visiting the monument, follow Highway 26 to Arco, where you will turn south towards Idaho Falls.

You need to merge onto Highway 20 shortly after Arco, as this will lead you directly to Idaho Falls.

Stay on Highway 20 through Idaho Falls, and then re-join Highway 26. The snake river twists and turns alongside the highway until you turn away from it at Swan Valley.

Follow Pine Creek Road, or Route 31, to the small town of Victor. Turn onto Highway 33 at Victor, heading south towards Jackson. Follow this road as it crosses the border with Wyoming and becomes Teton Pass Highway.

Teton Pass Highway will lead you to the edge of Jackson, where you will turn north onto Highway 191, leading to Grand Teton National Park and then to the south entrance of Yellowstone National Park.

Temperature-wise, you can't go wrong with visiting in the summer if you don't mind the crowds. The low 70s are the perfect temperature for exploring, and there are loads of events in the towns around Yellowstone in the summertime.

Winter is a great time to visit Yellowstone, as the park is quieter than in summer. You can also indulge in some great skiing at nearby Jackson. Hotels will remain expensive year round because of the popularity of the area for winter and summer sports.

That said, winters in Yellowstone can be very cold, so you must be well prepared if you want to visit in winter. There is no perfect season for a road trip from Portland to Yellowstone, as every season has its benefits and drawbacks.
