||Jordanelle Perimeter Trail
This trail is a doubletrack running around the northern and eastern
shores of the Jordanelle Reservoir at around 6000 feet elevation. It's
14.6 miles one-way. For early-intermediate riders, this makes it suitable
for a shuttled point-to-point or a partial-trail out-and-back. Strong
riders can easily hammer out the entire length out-and-back in around four
hours -- 29 miles with 2400 feet of overall climbing.
View east as we ride the eastern arm.
You can see the trailcut on the hillside. Original review 1998, new photos and update June 22, 2015
In the early days of UtahMountainBiking.com, photos
were shot on film using a disposable pocket camera, then scanned on a
flatbed scanner. They were published in a tiny low-resolution version
suitable for dial-up modems. Just for fun, here are fresh scans of the two photos from
the original review on June 11, 1998. These are two of my kids.

vegetation is lush as the trail approaches the water's edge and crosses
the creek. He was just three weeks short of his 16th birthday. He has two

return to the western trailhead just north of the big state park -- now rarely used. Gary was 14 in this photo.
The Perimeter Trail lies within Jordanelle State Park, a fee area. In
2021, that's $10 per car or $5 for a bike ride-in or for a Senior in a car.
(NOTE! The Hailstone area has a higher fee!) You can access the trail from the small-boat launch parking at Rock Cliff
off Highway 32 (east end), from the Old Highway trailhead off Highway 248
(north end), or by finding the old Mayflower trailhead on the west side
north of the main marina and campground.

|Ross Creek (Old Highway) Northern Trailhead
The Ross Creek trailhead on the north end (off 248 reached via the
Kamas exit from US-40) puts you on the old highway. Come prepared to stuff your fee
into the pay envelope -- it's illegal to park along the road uphill. After riding chipped
aging asphault for 0.6 mile from the trailhead, you reach the westbound
trail on your right. The southbound trail is another 0.4 miles further
down the old road. So for a southbound point-to-point (or out-and-back)
you'll find your trail on the left as you head down the road toward the
water, a mile away from the trailhead.
This trailhead also offers riding on the singletrack Wada
Way and Keetley trails.
Here the westbound trail forks to the
right off the old highway. To ride southbound, head another 0.4 miles down
||West (Mayflower) Trailhead
The west-side trailhead isn't used much, but isn't that tough to find.
As you pass the west side of the reservoir, exit US-40 toward Jordanelle
State Park. Immediately turn left. Stay on that road until you see a
settling pond on the left. The paved road drops over the edge toward the
water. (The trail ends on that road down below you, but there's no place
Turn left onto dirt and drive north along the dirt road east of the
pond (with the pond on your left) and pass the mine. 150 feet past the
mine, there's a wide area on the right, with doubletrack going downhill
toward the lake. There are no signs, bathrooms, or kiosk. Just a ramp
downward. Keep left and northbound as you descend.
Typical trail on the west side --
broad and grassy.
|This western section of trail doesn't see much use. It
really needs to link to the campground -- perhaps there are land-ownership
issues that have prevented this. I saw some bike tracks where adventurers
had headed for the Jordanelle State Park on the exposed dirt and rock
above the waterline. But it was bumpy, steep on the side-slope, and thistle-infested, so I don't
recommend you try it.
The State Parks people had mown the grass in the overgrown trail,
and the presence of fresh bike tracks the weekday morning of my ride confirms
that, yes, people still ride this piece of the Jordanelle Perimeter.
Looking east, just past the bridge
over the creek at the northwest corner of the lake.
||Rock Cliff (Nature Center and Campground) Trailhead
On the far southeast corner of the lake is the Rock Cliff
trailhead. It's found next to the bathrooms at the small-boat launch area.
There's a campground and picnic area along the road through the park.
The fee station was unmanned on a weekday, so you need a check or exact
change to stuff the envelope. (See the note below about parking in the Rocky
Top trailhead and paying the lower "ride-in" park fee.) Drive straight west until the road ends at the paved parking lot.
You'll easily see the
doubletrack trail at a ride-around to the right of the bathroom.
Looking west from the parking lot at
Rock Cliff. The trail begins at the sign to the right of the bathroom.
|The eastern arm of the lake will have fishermen moseying
along the first mile of trail. You'll likely encounter swimmers and
kayakers. Once you're past the first climb, you have the trail to
yourself. There were plenty of chipmunks, rabbits, deer, turkeys, geese,
and even a swan and osprey.
Those aren't ducks. It's two swimmers
getting their strokes at 8 am, before the power boaters make it dangerous.
||When westbound from Rock Cliff, the trail will rapidly begin
climbing, well before you've warmed up. The pitches can get a bit steep
and feature loose rock. Beginners will push-a-bike. Ridden east to west
there's one long pitch which, while do-able with pain and careful bike
handling, is such a grunt that all but the strongest elite will quit and
hike up. These four miles along the eastern arm of the lake are probably 90%
of the work of riding this trail.
Heading gently uphill about a mile
from the trailhead.
|If you're doing a point-to-point, I recommend riding north
to south. The slopes are less ugly in that direction. Very do-able in
granny gear for a conditioned rider, although it will be a challenge not
to spin out your rear tire where the surface has loose rock.
Cresting a hill (which you'll do
several times on this section of the trail), we're looking west toward the
ski slopes of Deer Valley.
||This eastern portion of the trail rises high on the hillside
above the steep slopes descending to the lake. Once you're past the rest area
at the "bend" of the lake -- actually just a marker now, the
bench is gone -- it's easy riding from there northbound.
Descending back closer to the shore.
For several miles, you're high on the mountain, well away from the water's
This isn't singletrack. Although motor vehicles are prohibited, regular
trips by maintenance vehicles mean this trail looks like a jeep road. And
like a jeep road. The pitches on the east arm are
too steep for beginners or early intermediates. But new riders would enjoy a
cruise out-and-back on the northern part of the trail. For strong riders,
it's training miles in a beautiful setting. And the rollers are your
intervals. So while Jordanelle wouldn't be a first choice to sample Utah
riding, it's worth doing.
The views of the lake and surrounding mountains redeem
this ride. If you can do it during the early morning quiet -- before the
gasaholics turn the lake into a nest of angry motorboat hornets -- it's a
fun crank. Put aside your "singletrack only" snobbery and you
might find yourself satisfied after 29 miles and 2400 vertical feet.
Looking across the reservoir toward
the state park campground, with a sailboat sitting idle waiting for the
breeze to pick up.
Mayflower (west) TH: On US-40, take the Jordanelle State Park
exit. Immediately turn left and follow this road until it's about to drop
to the water. Turn left on dirt road along a settling pond. As you pass a
small hill on your right, find a spot to park. The trail is the broad path
dropping off to your right. (Unmarked in 2015.)
Ross Creek (north) TH: Take the Kamas exit to Highway 248
eastbound from US-40. After cresting the hill and dropping into a small
valley around 3 miles from US-40, turn right at the sign for Jordanelle
and proceed to the parking area.
Rock Cliff (east) TH: Just south of the dam on US-40, turn east at
the light on Highway 32. After six miles, just as the road drops to the
valley floor and crosses the Provo River, turn left to Rock Cliff. Proceed
to the pay station. Keep straight until you reach the small boat launch
Scrooge McBike money-saver: If you're riding alone,
park just outside of Rock Cliff in the Rocky Top
Trail parking lot. Then ride your bike 1.2 flat pavement miles to the
trailhead. You'll pay the lower $5 "ride-in" rate, saving $5
(2021 fees) compared to the $10 one-car rate.
