Seattle to Denver Road Trip Guide


Seattle or the “Emerald City” is the largest city in the Pacific Northwestern United States. It is the birthplace of Starbucks Coffee and the home of “grunge rock”, a genre of rock music that gained popularity in the late 1980s and early 1990s. Seattle might get a lot of rain on a yearly basis, but on a good day you can see Mount Rainer off in the distance in all of its towering majesty. Rain or shine, people still venture out to Seattle and explore some of its awesome sights like the Space Needle or the Pike Place Fish Market. If you have some good catching abilities, you can probably catch one of the gigantic fish that gets tossed around a lot before it’s sold to its next customer.

As you are leaving Seattle and head east, you’ll be visiting some of the most beautiful and dense forests the Pacific Northwest has to offer. Most of the forests that you’ll be traveling through from Seattle to Denver will be federally protected forests. With Mount Rainier slowly disappearing off in the distance, you’ll still be surrounded by plenty of mountains as you continue you on with your trip that will span out across seven days. Lots of forests, mountains, and a world-famous national park will definitely be in your future when you travel from Rainer through the Cascades and right down to the Rocky Mountains. This road trip is an outdoor fanatic’s dream.

Denver is no stranger to outdoor enthusiasts. However, there are plenty of places that you can check out in the Mile High City. If you are a sports fan, check to see which sports are in season. You could watch a Rockies or Broncos game if it fits somewhere on the schedule. Plus, if you are traveling by way of RV, Denver has you covered with the number of RV Parks in the city or suburbs.

Point of Interest

Space Needle

Before leaving Seattle, you might want to check out the iconic Space Needle. You can check out the observation deck of this towering landmark and take in the view of the entire city of Seattle. Of course, you will also get a good look at Mount Rainier off in the distance. At nearly 14,000 feet it stands as one of the tallest mountains in the lower 48 states. Once you have finished observing the Space Needle, you can spend the rest of the day in Seattle. Especially if you are just spending the day in the city before you rest up and head farther east.

After exploring Seattle, there are a couple of RV parks that you can check out that are both located in the suburb of Bellevue that is just east of the city. One such place is the Vasa Park Resort, which is situated on the shores of Lake Sammamish. This park has plenty of activities that you and the entire family can enjoy.

Okanogan-Wenatchee National Forest

As you are heading east on I-90, you’ll be in the southern half of the Okanogan-Wenatchee National Forest. It is a forest that combines with a couple of national landmarks including the Mt. Baker-Snoqualmie National Forest and the Northern Cascades National Park. The forest has plenty of hiking trails for you to check out if you are more of the hiking type.

After hiking the trails, you’ll be able to see Chimney Rock West within your view. After a day of hiking, you can settle in for the rest of the day and night at Whispering Pines RV Park. It’s peaceful, serene, and will accommodate your RV or camper for the night.

Umatilla National Wildlife Refuge

If you are a fan of bird watching and love animals, you can check out the Umatilla National Wildlife Refuge. This refuge sits on the banks of the might Columbia River, but you’ll be able to catch much of the action on the Oregon side. Just take US Route 730 and head west out of Umatilla. Don’t worry, you’re not going far out of the way. While you are at the refuge, you can talk a nature walk, do some fishing, ride horses, and even observe the wildlife.

After a day at the refuge, you can spend the night at the Boardman Marina and RV Park just off the westbound side of I-84. You won’t be too far off the Interstate since you’ll be hopping back on it the next morning (only this time in the other direction).

Morley Nelson Snake River Birds Of Prey National Conservation Area

If you cannot get enough birdwatching, you might want to check out the Morely Nelson Snake River Birds Of Prey National Conservation Area deep in the heart of Idaho. This is a place that is surrounded by beautiful landscapes and is home to many birds like falcons, hawks, and eagles. Whether you want to observe with binoculars or take plenty of pictures, you have so many opportunities to do so. You should check out the area that is located due south of Boise. You can also do plenty of hiking here if you are more inclined to do some walking around and exploring.

The closest RV parks will mostly be located in the City of Boise. The Mountain View RV Park is a great place to settle in for the night. Even if your RV is large, you can still be able to get a good amount of space to set up and relax.

Craters Of The Moon National Monument & Preserve

After spending much of your travels in Idaho on I-84, it’s time to turn off the Interstate and hop on US Route 26 outside of Twin Falls. Your first “must-stop” on this roadway is the Craters Of The Moon National Monument Preserve. More than thousands of years ago, this part of the United States was volcanic. And it’s uncertain when the next batch of activity will happen next.

These mounds of land were formed by dried lava. It might change over the course of many years. People have said that volcanic activity will likely occur here again at the craters. But the question of “when” is often asked. Once you have finished your day of exploration, you can settle in and grab a bite to eat at Mountain View RV Park and Restaurant (not to be confused with the RV Park in Boise). Only this time it has a restaurant located on the grounds. If you are not in the mood to cook on the grill, you can grab yourself something close to a home-cooked meal.

Caribou-Targhee National Forest

At this point, you’ve probably been through so many national parks, forests, and landmarks. But this is just one of many as you are traveling towards Denver. The Caribou-Targhee National Forest covers most of Idaho and Wyoming but also covers portions of Idaho and all the way down into Northeastern Utah. This part of the forest you’ll be going through will sit due west of Yellowstone National Park. Depending on the season, you can do plenty of outdoor activities here like hunting, fishing, hiking, and walking. If you are a skier or snowboarder, you’ll enjoy carving through some fresh, untracked snow. You can explore the forest on foot or on horseback. No matter how you do it, you’ll be able to soak in nature the way you want.

After exploring the day in the forest, you can settle in for the day at some of the RV campgrounds like the Warm River Campground on the southern edge of the forest. Alternatively, there are plenty of RV parks near Yellowstone National Park on both the Idaho and Wyoming side of their respected borders.

Yellowstone National Park

This is probably one of the most famous national parks in America and for very good reason. You can witness the awe of the numerous amounts of hot springs and geysers erupting, including Old Faithful. Of course, Old Faithful erupts consistently and right on schedule. You do not want to miss it, even if you have to wait a couple of hours (trust us, it’s worth it). Geysers, mountains, bison, and so much wildlife inhabit this park. You’ll want to spend at least a day or two here depending on the schedule.

Don’t be shocked if the RV parks near Yellowstone are busy and space can be hard to come by. There are plenty of them located near the park or as you are heading towards Grand Teton National Park. Or, you can save yourself the headache and stay an extra night at your previous spot before heading south to our next destination.

Grand Teton National Park

Just to the south of Yellowstone is the mountainous Grand Teton National Park. This is where you can partake in so many outdoor adventures like hiking, rafting, and so much more. We were not kidding around when we said that this was the road trip of a lifetime for anyone who loved the outdoors. This is a great place to stop in visit no matter what time of year it is. If you are traveling while there is snow still on the ground, that’s where the mountains really pop visually.

Once again, this is a park with plenty of RV parks than you know what to do with. If one of them has little to no space available, you’re always bound to find something elsewhere within a close range.


Finally, you have reached the Mile High City after visiting so many national parks and monuments along the way. You have managed to travel through the Cascades region to the Rocky Mountains. By this time, you might have a love and even deeper appreciation for those majestic bodies of land. Denver has plenty of activities that you and your entire family can enjoy. If you are a sports fan, you can catch a Rockies baseball game at Coors Field or a Broncos game at Mile High Stadium. You can also explore the many parks and museums in the downtown area while you are out walking around.

Denver does have some private and public campgrounds where you can park your RV. But if you want a bit of peace and quiet, you can find one that’s a bit out of the way. One suggestion is the Clear Creek RV Park. It’s close to a lot of hiking trails and is located on the outskirts of the Denver Metro area.
