ABSOLUTELY DO NOT TAKE AR HWY 74 to Devil’s Den with a rig your size.
Hwy 220 from Cedarville is the least traffic, least grade into Devils Den, however it is 15 miles of unpacked road.
Hey 170 from West Fork is my preferred route. There is a mildly steep uphill grade from West Fork. The grade down into the campground is quite steep for the last half mile. Neither is a challenge to your truck.
270 is a good 2 lane road, but not much shoulder. Just take it easy and enjoy the view.
The best sites are in a level shaded two loop full hookups area right near where 170 meets 74 and 220.
Call the park before you leave West Fork, or other entry route and verify which space you will be using. Drop the trailer before you go to register.
There is not room for your trailer at the park office.
There is no cell service or TV/ radio reception in the main area of the park. It is a steep sided valley and the campground is on the bottom alongside the creek.
Devils Den has been my favorite campground anywhere since my first visit in Oct 1970. I don’t get back there as much as I like. Usually only once a year. But I love it.
