Colorado plays host to a myriad of breathtaking mountain roads that will inspire awe and wonder in equal measure. They span the length and breadth of the state, encompassing some of the most beautiful scenery that you’ll find in the entire of North America.
There is something for every taste and every level of experience – from the hair-raising heights of the unpaved Mt. Bross mountain road, famed for being the highest road in the United States, to the paved Mt. Evans Scenic Byway, which is ideal for intrepid beginners, you name it and you’ll find it in the Centennial State. If you’re looking for adventure, fun and profound natural beauty, then check out the highest roads in Colorado!
What is the highest road in Colorado?
The highest unpaved road is Mount Bross at 14,178 feet. It’s located in northern Park County beside Alma. This rocky dirt road just barely beats out the highest paved road is Mount Evans at 14,130 feet. The latter can be accessed by nearly anyone with a working 2WD low clearance usually from late May to mid October. Whereas that is not the case with Mount Bross where you’ll need a solid 4×4 and additional skill behind the wheel.
Colorado’s Highest Paved and Gravel Roads

Often the higher you get the better the views. You can be assured an incredibly scenic journey on one of the following roads. Most are gravel rocky roads only suitable for high-clearance 4×4 with an experienced driver. The asphalt ones are usually suitable any commuter car to make it to the top.
Aside from Pike’s Peak and Loveland Pass, which are accessible year round and only close temporarily due to winter weather conditions like snow, all the rest of the highest roads in Colorado are seasonal and usually require you to wait until at least after Memorial Day to think about driving up it. Some not until later in the summer.
Most of these roads are all seasonal, only granting access after the winter snow melts from their roads in late spring to early fall. You’ll also need a durable, high-clearance 4×4 if you going to make most of these treks. If that doesn’t sound like you, consider some of Rockies top mountain passes that give you a taste of high alpine life.
On the other hand if you’d prefer looking up at the mountains as you drive instead of down at the clouds, consider one of these scenic byways. They ensure a remarkably stunning drive with plenty of tourist stops on the way. It’ll also limit your exposure to heights and mountain switchbacks. Safe driving!
