Flume Trail (Dry Fork, Vernal)
The Flume Trail is a singletrack along Dry Fork, northwest of Vernal. It features beautiful
scenery plus some butter-smooth singletrack interrupted by a smattering of technical challenges.
The epic ride is 20 miles, with 1600 feet of climbing to an altitude of 8300 feet. But because
of the multiple trailheads, there are options for shorter rides and for non-technical cruises.
Overall, the ride is intermediate in tech requirement, but there are a few areas that non-advanced
riders will walk. The ride follows the course of Dry Fork at a gentle rate of climb. You're
surrounded by aspen, fir, and pine forest with occasional breakout views. While the highlight
of the ride is a visit to the old flume site, the trail itself is one of the best you'll do.
Bridge across Dry Fork at Trailhead 2, which is the first trailhead on the Dry Fork Road. At the water's edge, birch trees add to the greenery.
A nice buff trail section. Riding downhill is a grin-generating experience.
View over non-dry Dry Fork. Pretty ride! And a bit different from other Vernal trails.
A line-picking exercise. Good bike control and balance gets you through this tight spot. The arrows show the route.
The lower two miles offers the most technical riding. The trail twists as it goes up and down,
with a few rock gardens that are fun to navigate. The first mile is a bit of work both uphill
and down. This first section would be upper-intermediate in tech requirement, with a few tiny
After the next trailhead (at mile two), the trail is quite mellow for a couple of miles. This
is the easiest section both in terms of aerobic grunting and technical control. I recommend
the section between trailhead #2 and Brownie Creek for beginners. It's a great cruise.
A log has been converted into a rollover. These are all on the lower section, including a couple between the alternate trailhead #1 on Sawtooth Cove Road and trailhead #2.
Lumber ramp over a side-stream. It tips a bit side to side. I think it's less scary to ride than to walk across.
After mile 3, there are three spots where the trail briefly joins the gravel road. Ride up
the road and watch for a 4x4 post on your left to resume the singletrack. On the day of my
ride, all of these sections had flags placed in the brush, marking where new trail is going
to be cut to avoid these detours onto the road.
At the campground by Brownie Creek, the continuing trail curves 0.4 miles toward Dry Fork.
This section has a lot of boulders and deep sand. You need to ford the creek to continue. On
the day of my visit, Dry Fork was Not Dry. Thigh-high water made crossing a potentially-deadly
impossibility. If water prevents safe passage, backtrack and continue a couple of miles up
the road to catch the upper trail.
The passage through the creek is closed by high water on June 3.
Just a sample of a rock garden waiting to hang up your front wheel. I didn't have to walk any of them. Big bike, big muscle, and big speed gets you through.
There are periodic rock gardens. When you hit these, pick your route quickly and carefully.
Keep your speed up and you can bang over them. I appreciated full suspension and 29-inch wheels
on these spots. Intermediates who want to "take it slow and careful" will get tossed off their
bikes. It's "ride it fast or don't bother."
At the primitive upper camping area (mile 17 from Vernal), there's a nice 1/2 mile nature hike.
The trail is well-maintained, with markers corresponding to teaching material in self-guiding
pamphlets. Bikes are allowed, but I'd recommend walking if significant numbers of hikers are
on-trail. Good spot for kids.

Upper trailhead. The footbridge takes you to the 5-mile loop featuring the ruins of the flume.
Many riders opt to do only the upper loop, driving directly to the top trailhead. OK. But the
lower canyon is soooo much fun. The upper loop has a mile of fairly tricky trail that's not
at all suitable for beginners. Or timid intermediates. The northern (return) side of the loop
is one long rock garden. Advanced riders won't think it's so bad.
The upper trail starts with three miles of very nice buff singletrack as you climb. Then the
monster emerges. The trail turns downhill and gets rough. Embedded boulders, loose rocks, as
the trail twists through pine forest. Sometimes it's hard to quickly spot what's trail and
what's mountainside. After about 2/3 mile of this, you hit a "T" intersection. Turn left to
go down to the flume site. The right fork will be your return trail to complete the loop.
Sample trail view as we climb uphill on the loop.
Heading downhill toward the flume site, trying to pick out trail among the shadows of the pines.
At the flume site, several log towers remain. The flume was an elevated "ditch" -- an attempt
to channel water past a sink where it disappeared into the earth. That's why Dry Fork becomes
dry once the early runoff is complete. The flume was built in over 4 years in 1893-1897, but
leaked so badly it washed its own towers away. The flume (and the small town of workers at
the site) was abandoned.

From the middle of Vernal, go north on Highway 44 to 1500 North (Highway
121 to Lapoint) and turn left. Drive west to 3500 West and turn right.
Zero your odometer here. Drive north on 3500. It will veer to the west as
it becomes Dry Fork Road. 8.4 miles from 1500 North, you'll reach an
intersection where Dry Fork Road turns a sharp 90 degrees right. (You'll
see it descending to cross the creek.) Straight ahead is
Deep Creek Road. Turn right to follow the Dry Fork Settlement Road north through the valley. At
mile 9.2, turn left (Dry Fork Road = Red Cloud Loop Road).
