Technical Ratings & Terrain

Avg Technical Rating: 2-3

Peak Technical Rating: 4

Typical Terrain: The track features a solid amount of moderate trails. In addition to these rockier, steeper, and bumpier trails, there is still a significant amount of graded dirt and gravel roads, and some interconnecting pavement.

Recommended Vehicle / Moto / Adventure Vans

Recommended Vehicle: Stock 4x4

Recommended Moto: A mid-weight bike is recommended given some of the moderate terrain.

Adventure Vans: Sprinter 4x4s can take on a modified version of the track. To bypass some of the moderately rated sections that are likely to give Sprinters trouble, take While Sprinter's can explore large portions of this track, there are numerous sections which may pose challenging for Sprinter 4x4s. These include Josie Morris Trail, McKee Bench, and Sears Canyon just to name a few. It is possible to bypass these sections take the following alternative routes: Blue Mountain Bypass, Diamond Mountain Bypass, and Crouse Canyon. More info is available under the alternative routes sections.

Fuel, Provisions, and Recommended Gear

Fuel: Depending on where you fill up, it's roughly 160 miles to reach fuel in Vernal area (you'll need to leave the main track). From Vernal it's roughly 235 miles to reach the end of the track and fuel in Maybell. These distances can be cut down by skipping many of the out-and-back portions of the track, such as the drive to Zenobia Peak. There is an option to refual near Flaming Gorge, but this is 32 miles (one way) from the John Jarvie Historic Ranch. Provisions: Provisions can be obtained in the same general vicinity as fuel. Gear: no specialized gear is recommended for this adventure.

Alternative Routes

Blue Mountain Bypass Distance: 33 miles Technical Rating: 1 (pavement)

Sprinter vans and other vehicles that may not be well suited to moderate trails should take the Blue Mountain Bypass, which skips the moderate terrain along the Josie Morris trail. Diamond Mountain Bypass

Distance: 11 miles

Technical Rating: 1 (pavement) This is another bypass recommended for Sprinters and similar vehicles to skip the moderate trails up McKee bench to Diamon Mountain.

Crouse Canyon

Distance: 14

Technical Rating: 2

Crouse Canyon is the alternative to taking on the more moderately rated Sears Canyon. Crouse Canyon is a relatively dirt road that passes through the rather scenic and rugged Crouse Canyon. The scenery through both Sears and Crouse Canyons is rather impressive, so it's hard for us to choose which one we enjoy more!

Camping Recommendations

Dispersed camping is not permitted within Dinosaur National Monument. However, there are a number of impressive campgrounds within the national monument with spectacular views of the Green River and Yampa River canyons. Most campgrounds within the park are first come, first serve. If you're camping outside of the monument, please make sure you're on public lands, as there is a significant amount of private property along the sections north of the monument. We have marked a number of dispsered sites on public lands to make finding camp easier. Some of our favorite places to camp along the track

• Echo Park (first come, first serve)

• Rainbow Park (first come, first serve)

• Deerlodge Park (FCFS, but requires short walk to campsites)

• Diamond Mountain/Rim Road vicinity

• Crouse Canyon

Route Details

Dinosaur National Monument is at the center of the Jurassic Discovery Trail. At over 200,000 acres, the park spans the northern borderlands of Utah and Colorado. Fossils were first discovered in Dinosaur National Monument in 1909. Six years later, in 1915, after additional discoveries, the area was declared a national monument, and in 2019, Dinosaur National Monument was designated an International Dark Sky Park.

Many of the park's incredible river canyons, like Echo Park, were nearly flooded in the name of the Colorado River Storage Project. After much debate and controversy, conservationists were able to protect the canyons along the Yampa River from the proposed Echo Park Dam. Sadly, other canyons, like Glen Canyon, succumbed to the project needed to support growing populations in the American Southwest.

The track begins and ends at the pavement of Highway 40, and while it's possible to explore the loop in either direction, this guide follows a counterclockwise orientation. Your adventure begins on a wide dirt road that eventually leads to Yampa Bench Road. For the most part, Yampa Bench Road is a wide dirt road with occasional bumps and washboards. As you make your way into the park, the rugged and deep canyons the Yampa River has carved out over the eons begin to come into view. Traveling west along the bench, overlooks like Wagon Wheel Point (discovery point) and Hoarding Hole feature incredible vistas of the Yampa River as it twists and turns through the canyons.

Yampa Bench Road eventually leads you to Echo Park Road, which descends to a campground of the same name. Before reaching the Green River, be sure to stop at the Historic Chew Ranch (discovery point). Jack Chew built his house and ranch here in 1910. In 1966, his son Rial Chew sold 1,900 acres of the ranch to the national monument, and the park has preserved many of the old ranch buildings and much of its farm equipment as well. Echo Park Road eventually leads to the Green River near its confluence with the Yampa River. Here, Steamboat Rock (discovery point) is the star of the show. Dispersed camping may not be permitted within the national monument, but impressive campgrounds like Echo Park take full advantage of nature's splendor.

Retrace your tracks back up the hill and then continue on through Sand Canyon (discovery point). Like many places along Colorado's Western Slope, the terrain here is filled with a variety of geological oddities and unique rock formations. The rocks of Sand Canyon are a pale khaki, unlike the red rocks that abound on the descent down to Echo Park. Next up, follow the pavement to the end of the road for a quick hike out to Harper's Corner (discovery point). Harper's Corner may feature the best view (at least one that's easily accessible) within the national monument. You'll get a totally different view of Steamboat Rock and Echo Park, which sit over 2,000 feet below.

From Harper's Corner, the track jumps onto one of the local favorites, the Josie Morris Trail. The dirt road climbs to the top of the Blue Mountain Plateau before it abruptly begins descending down the mountain. This is another moderate section of the track, with numerous opportunities to test your rig's hill climbing abilities upon reaching the red rock badlands near the bottom of the mountain. The track leads to Josie Morris' cabin (discovery point) and the Hog Canyon Trail. Josie was a legendary figure in the American West. Popular legend claims that she harbored well-known outlaws on the run at her remote cabin, which seems to be supported by her close ties to Butch Cassidy's gang. Just around the corner from Josie's cabin is the scenic Hog Canyon.

The trail from Josie Morris' cabin to the Quarry Exhibit Hall is a mixture of graded dirt, moderate trail, and then a short stint on pavement leads to the hall and park visitor center. The Quarry Exhibit Hall (discovery point) is easily one of the highlights of Dinosaur National Monument. With over 1,500 fossilized bones, there are eight species of known dinosaurs remaining in the quarry wall, dating back to 150 million years ago (Jurassic period). The Fossil Discovery Trail (discovery point) is a nice complement to the hall. The 1.2-mile trail passes through the Morrison Formation, which features an outcropping with small fossil fragments in addition to a few large remains of dinosaur bones.

The track continues north into the remote backroads and trails of the Uinta Mountains. Follow McKee Bench to the top of Diamond Mountain, which features fantastic views of the canyonlands within the national monument. The track follows the rim, eventually wrapping around to the rugged Sears Canyon (discovery point). This tight and narrow track crosses several streams and was once a mail route. Follow the route until crossing the Green River, which leads to John Jarvie Historic Ranch (discovery point). After visiting the ranch, continue east above the Green River below, but be sure to stop at the Swallow Canyon Overlook (discovery point). Just around the corner, you'll cross the Browns Park Swinging Bridge (discovery point). This one-lane suspension bridge, built in 1913, is a favorite point of interest, but keep in mind, your vehicle must be less than 8'6" in width to make it across the bridge (which shouldn't be a problem unless you own a behemoth of a rig!).

The remainder of the track follows a series of dirt and gravel county roads through the junipers of the high desert. A short out-and-back brings you to the Gates of Lodore Campground. You'll want to take the short 0.75-mile hike to get the best view of the Gates of Lodore (discovery point). Working your way towards the pavement, there is an option to drive up to Zenobia Peak lookout (discovery point), which is the highest point along the entire track at 8,993 feet. The final discovery point can be reached by driving to Deerlodge Park, and another short hike will take you to spectacular views of the Steps, Vale of Tears, and the Yampa River Canyon (discovery point). Follow the pavement of Dinosaur Park Service Road back to the highway, where the route officially concludes.
