RV route guide
Denali Highway — Paxson to Cantwell
135 miles of remote Alaska Range scenic. Mostly gravel. Genuinely empty country. Plan for a slow day.
The Denali Highway runs 135 miles from Paxson, Alaska, to Cantwell, Alaska, connecting the Richardson Highway with the Parks Highway. Only the first 21 miles from Paxson and the last 3 miles to Cantwell are paved; the central 111 miles are gravel. Despite the gravel surface, the road is maintained at moderate quality and accommodates RVs with reasonable suspension. The byway crosses the Alaska Range south of Denali and offers some of the most isolated scenic driving in North America.

Can I drive my RV on the Denali Highway?
Yes if you accept driving gravel. The central 111 miles are gravel — well-maintained, but rough enough that vibration is constant and dust is real. Class A motorhomes routinely make the drive but the brake and suspension wear is non-trivial. Many RV rental contracts prohibit driving on unpaved surfaces — verify before driving. The route is closed roughly October-May for snow.
- 135 miles, mostly gravel surface

What Alaska tourism + The Milepost doesn't tell you
The Denali Highway gets a fraction of the Parks Highway and Seward Highway traffic. That's a feature for travelers willing to drive gravel. The byway crosses some of the most isolated scenic country in North America with views into the Alaska Range that the more-traveled Parks Highway cannot match.
Tourism boards undercommunicate the gravel reality. The 'highway' designation suggests paved; only the endpoints are. The Milepost is honest about the gravel surface, but many online sources are not.
BLM dispersed camping along the route is a feature. Free, primitive, scattered along the corridor. Class B campervans pack in and enjoy the experience.
Frequently asked questions
- Is the gravel rough?
- Maintained at moderate quality. Class A motorhomes drive it with patience. Expect dust and vibration.
- Can I camp anywhere?
- BLM dispersed camping along the corridor allowed. Use no-trace practices.
