By Pat Dorri | Updated on 25 March 2022

The majestic Rocky Mountains separate the cities of Portland and Denver. If you want to go on a memorable adventure driving through the heart of this famous mountain range, consider a road trip from Portland, Oregon to Denver.

The 1,600-mile road trip from Portland to Denver takes 29 hours of pure driving. Notable attractions include Umatilla and Payette National Forests, Craters of the Moon Monument and Preserve, Rocky Mountain National Park, and Salt Lake and Twin Falls.

If the sound of a mountain road trip intrigues you, read on for more details about where to stop, the best route to take, and what to see along the way.

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

The road trip from Portland to Denver is approximately 1,600 miles. You could drive this in as little as three or four days, although it would be better to take at least a week if not more. Try to factor in at least one extra day for every city or town you might want to stay in.

The route encompasses dramatic mountain scenery and interesting cities, so it would be a shame to rush the trip - all the prettiest forests and parks come in quick succession on this trip, so slowing things down will definitely be rewarding.

There are a few areas where traffic could be a problem, notably Boise, Salt Lake City, and the outskirts of Denver. The best advice would be to avoid these areas at rush hour, so consider your timing before you set off.

With all that said, Salt Lake is technically an optional stopover along this route anyway, so all things considered, you can expect the majority of the drive to be relatively free of congestion.

The route mainly consists of interstate driving, which makes it a very quick and easy route. This also makes the route suitable for winter driving, and many of the destinations on this road trip are popular winter sports places.

Best road trip route from Portland to Denver

The best road trip route from Portland to Denver will take you across the breathtaking Rocky Mountains, past the Great Salt Lake, and into Denver. This route also happens to be the one packed with the most scenery, making it your best pick by default.

There is a small fork in the road in the second half of the route that offers some variation depending on the time of year you visit - neither pick is 'better' than the other, so consider taking one on the way to Denver and the other during the return trip to change things up.

Take Interstate 84 out of Portland, driving between Mt Hood and Gifford Pinchot National Forests. Just before reaching Snake River, the route is flanked by Umatilla, Malheur, and Wallowa Whitman National Forest - explore these places before pulling into Idaho.

Next up are Payette, Boise, Sawtooth, and Salmon-Challis National Forests, followed by Twin Falls. Take a break here, then move on to visit Craters of the Moon Monument and Preserve just north of town.

Once you're done there, you have two options for the rest of the drive - one thing you can do is stick to Interstate 84, then taking Interstate 15 through Salt Lake, followed by Route 40 past Ashley State Forest in Utah.

Past Manti-la Sal National Forest, get onto Interstate 70 and travel east, passing the likes of Uncompahgre, Gunnison, and White River National Forests before finally arriving in Denver.

For something a little different, back at Twin Falls, you can switch to Interstate 86 instead and cut through Wyoming - this gives you the option to detour to Idaho Falls, Bridger-Teton National Forest, or even Yosemite National Park if you have the time.

Once you're done there, Get to Pocatello, then follow Routes 30, 129,28, and 287 to Interstate 80 in Rawlins. Take the interstate and drive past Medicine Bow-Routt National Forest and Pawnee National Grassland before pulling into Denver.

Best time to go on a road trip from Portland to Denver

One of the best aspects of this road trip from Portland to Denver is that you can go at any time of year. While the mountains will get cold in winter, there is still plenty to do, and the roads remain drivable.

One thing that's amazing about the drive itself is that, with so much to see on the way, you can find something to enjoy no matter the season - for example, even if the forests are closed in the winter, you'll be passing by countless mountains and skiing resorts you could access.

Speaking of which, winter in some of the mountain resorts can be as busy as summer, particularly places like Vail. This means the hotels remain expensive year-round so travel when best suits you.

Denver is very cold and gets regular snowfall in winter. Comparatively, in summer, it is very warm and sunny, although Colorado isn't generally the kind of place people visit to bask in the sunshine!

If you enjoy skiing and winter sports, then I would recommend a winter road trip. However, if you detest the cold and enjoy going hiking, summer or the shoulder seasons are a better time of year for you.

Whenever you choose to go, be sure to pack lots of warm clothes - mountain climate can be unpredictable, so you won't want to have your stay ruined by an unexpectedly cold day.
