Rims Road — Dinosaur National Monument Echo Park Desert Circuit
Two rivers. One brutal clay descent.
The Echo Park Road off Harpers Corner Drive in Dinosaur National Monument is one of the more deceptive descents in the Colorado Plateau — a 13-mile dirt road that looks manageable on paper until it hits the notorious clay switchbacks above Echo Park itself. When dry, it’s a high-clearance run with sweeping views of Split Mountain, the Yampa and Green River confluence, and Steamboat Rock rising 800 feet from the canyon floor. Whirlpool Canyon stretches below, and the campsites at Echo Park put you at one of the most remote river confluences accessible by vehicle in the American West.
This road closes the moment it rains — the clay section above the final descent becomes impassable even for prepared rigs. Four-wheel drive is required. Traction control helps but isn’t a substitute for momentum management on the way back out. A campsite reservation is required for overnight stays at Echo Park Campground. Fuel and supplies come from either Dinosaur, Colorado or Vernal, Utah — neither is close. Cell service is nonexistent once you leave the highway. Best season is May through October, with June and September hitting the sweet spot before heat and monsoon season respectively.

Frequently asked questions
Can a stock Jeep Wrangler or 4Runner handle this trail, or do I need a built rig?
A stock high-clearance 4WD like a Wrangler or 4Runner can make it, but airing down is non-negotiable. The Steer Ridge clay descent has loose rock and tight switchbacks that will punish street tires and test your skid plates — lockers are a serious advantage, not a luxury.
What happens to the road when it rains?
The clay sections become undrivable when wet — NPS will close the road and you will not make it out without getting stuck or sliding off an edge. Check the forecast before you go and build in a buffer day; conditions can change fast in the high desert.
Do I need a permit to drive Rims Road and camp at Echo Park?
Yes. You need a paid entry pass for Dinosaur National Monument ($25/vehicle as of 2024) and a separate backcountry camping permit if you're staying overnight at Echo Park. Get the camping permit in advance through the park — sites fill up, especially May through September.
How bad is the Steer Ridge descent and what should I actually expect?
It's the crux of the whole route — a steep, narrow clay road that drops roughly 2,000 feet with minimal room for error and no guardrails. Use low-range 4WD, go slow, and know that if you meet another vehicle, one of you is backing up a long way.
Is there any water or fuel available along the route, and how far is the nearest gas?
There is no water or fuel on the trail — the Green River at Echo Park is not a reliable drinking source without heavy filtration. Fill up in Dinosaur, Colorado before you head in; it's the last real fuel stop and sits about 40 miles from the trailhead.
