Dinosaur National Monument
Harpers Corner

Yampa River canyon

Harpers Corner is a long drive from anywhere, and when you finally arrive you might think you've seen all you could see on the drive in. You would be wrong - the views as you walk are astounding.

Different views are seen as you move along - a road deep in a canyon far below, tall cliffs foreshortened to small bumps, rushing rapids made tiny by the vast distance but still audible in the palpable silence.

From the junction of US-40 and US-191 in Vernal Utah, follow US-40 east 35.2 miles to the entrance road to Dinosaur National Monument.
Take a left onto the entrance road and follow it north 31.5 miles to the end, where there will be a parking lot for the Harpers Corner Trailhead. There are numerous overlooks along the way, and I would highly recommend stopping at each and taking a look.
Be sure to stock up on water before leaving US-40.
Coordinates for the hike: 40.5241700,-109.0205800
Parking / Trailhead amenities
The parking lot is paved and large. There is a pit toilet adjacent to the lot, but no other facilities.
Trail observations
Harpers corner is a moderately easy out and back trail with stunning vistas of the surrounding canyon country. The views are incredible, and there is a lot to look at. I recommend bringing binoculars and giving yourself plenty of time for site-seeing.
I've hiked this trail in winter, spring, and fall, and I've felt overheated every time. Bring plenty of water on this hike!
