Bonneville Shoreline Trail
The Bonneville Shoreline Trail is a series of trails along the slope of
the Wasatch Mountains where the old shoreline of Lake Bonneville met the hills. Sections
of trail are found from Brigham City to Payson. This section is 10.5 miles from
Ogden Canyon to North Ogden Canyon. See the main Ogden
BST page for southbound BST information from Ogden Canyon, and the Pleasant
View BST page for northbound from the North Ogden Divide Road.
Looking up at the mountains, an
unfinished marker post will guide riders past a connector trail. Original
review 2006. Photos
and updated ride descriptions by Bruce on April 25,
2012 for south of the Nature Center and June 9, 2015 for the new trailcut
north through Coldwater Canyon.
|The main trail connections are to the BST northbound (Pleasant
View) and southbound (Ogden), and to the
North Ogden Divide (via Parallel Canyon Rd aka Old North Ogden Pioneer Rd)
trailhead for Northern Skyline and Lewis
Peak trails. There are several connectors to trailheads and
neighborhood roads along Harrison Blvd, which becomes North Mountain Road.
See big topo map.
The Paved Ogden River Trail passes
under highway 39 directly to the trailhead. This invites
pavement-plus-dirt loops for the locals. If you work south of the Rainbow
Gardens parking, you'll find the southbound Ogden BST.
||Originally, I considered this trail advanced technical
because of steep hillsides with narrow trail plus gnarly rock gardens on
the singletrack north of North Jumpoff. With some reworking of these older
sections in 2015, I can now recommend the ride for intermediate riders.
You can skip some of the more technical trail by taking the lower trail
northbound from the
Nature Center, see below.
Stronger riders can do the entire thing out-and-back, or one-way with a
road return. Most riders will do either the northern or southern half, so
this page will be split into two parts: south and north.
Just getting started. We're climbing
north away from the trailhead.
Part 1: Southern Half, Ogden Canyon to Ogden
Nature Center trailhead
|From the south end, the ride begins at a new paved parking area on the north
side of Highway 39, right across from Rainbow Gardens. There's a bathroom
at the trailhead. The trail is on the eastern end of the pavement. It
immediately begins seriously climbing the hill.
As we rise on the mountain, we spot
dirt jumps in the old gravel pit.
||Keep right at the first fork 1/2 mile up the mountain. The
left fork takes you to a subdivision road above the gravel pit. Climb on
The terrain has a mix of rough granite, gneiss, and quartzite. These
rocks are Precambrian -- some of the oldest rocks in Utah.
It's a bit of a smoggy day. We're
looking northwest across the wildlife refuge at the northern end of the
Great Salt Lake.
|As you reach the gravel road, turn left to find the
continuing singletrack on the uphill side. (If you want a look up Ogden
Canyon, pedal south on the gravel road as it turns around into the canyon.
Then clamber up the cement stairs to the viewpoint. Return to the trail
crossing to continue your ride.)
The canal road provides another riding option. It's an easy cruise
northbound. After about 1/3 mile, there's a gated fence between two rock
outcrops. This gate is sometimes locked. Real bikers do NOT ride the canal
We're about to get into some crunchy
rough rock, as we pass outcrops of granite intruding under the quartzite.
||The trail will climb up and over a ridge, with plenty of
views over the Ogden Valley. When wind clears out the valley smog, you can
see a long way out over the western desert. For the ride from Ogden Canyon
to the Nature Center, altitude gain is 500 feet, with about 800 vertical feet of
total climbing each way.
A rider climbs up and over the ridge
at the southern half's high point.
|The next connector trail is at mile 1.4, just as the trail
turns into a small canyon. Keep uphill and to the right. There will be
bailouts to the canal road and to subdivisions below it periodically along
Arrowleaf balsamroot blooms in the
April sunshine. Balsamroot looks a lot like the mule's ear you see at
upper altitude. But balsamroot has only flower per stem and the leaves are
large, arrow-shaped and fuzzy. Mule's ear has branched blossoms and
spear-shaped shiny smaller darker leaves.
||The trail descends back to the level of the canal before
climbing away from it again. Keep generally to the right and uphill as you
pass the Douglas Trail and Polk Trail.
The trail is pretty well marked for
the first four miles. Here the Superfly rests against a marker for a
subdivision connector trail.
|The next connectors will be South Jumpoff and North Jumpoff,
which will join lower in Jumpoff Canyon and connect to a subdivision
trailhead. Beyond North Jumpoff, the trail gets significantly more
technical, with some bumpy rock gardens and tight derailleur-killing
After coming around Jumpoff Canyon, we
see Ben Lomond in the north. Our destination is the broad area at the base
of the mountain, where we can continue on the BST past North Ogden Canyon.
||Intermediate riders can make a loop around the Jumpoff
Trails (North then climbing back up on South) to head back. Or you can
drop down to the Nature Center for a road return. If you're
headed northbound, you can take the nature either descend to just east of
the Nature Center parking and take a northbound trail for a less-techy
ride. But as of 2015, the challenging tech rock just north of the Nature
Center connector has been blown up and beaten down to an intermediate
If you're planning a road return from the Nature Center, it's 3.5 miles
back via North Mountain Road (Harrison Blvd) then Highway 39.
Ahhh... I really miss those truly nasty sections of bike-breaking quartzite.
This is nothing.
|Northbound riders who want to skip the big climb around
Coldwater Canyon can bail onto the canal
road at mile 4.7, which will take you to North Mountain Road just south of
the Pit (Coldwater Canyon) trailhead. (At this point, if you're not
"done" you can climb up and finish the BST northbound, or
bushwhack 1/2 mile through some complex trails to the Divide road TH, or
head west a bit on 2750 North until you reach a northbound 1050 East which
will take you to 3100 North -- the Divide road.).
Heading back southbound, Mount Ogden
sits on the skyline.

Part 2: Northern Half, North Ogden Canyon (Divide) Road to Ogden
Nature Center trailhead
The trail starts on the south (downhill) side of the North
Ogden Canyon (Divide) Road. There's parking space for 5 to 6 vehicles but
no other trailhead stuff. (Across the street and a bit uphill is the northbound
BST.) Drop downhill, keeping straight as you pass the connector to the
Old Pioneer trail. The trail will descend a bit as it heads east into
North Ogden Canyon, before crossing the broad trail in the bottom of the
canyon. This trail is known as Parallel Road, North Ogden Divide Trail,
and Old North Ogden Pioneer Road. (If you want a mean climb, head uphill
on this trail. It ends at the Northern Skyline
and Southern Skyline trail parking.
from around mile 0.8, as we've crossed the broad trail heading from the
Pit trailhead up to the top of the pass. These photos June 9, 2015.
The trail will climb gently as it heads back to the west out of North Ogden
Canyon. As it rounds the corner to turn southbound above the valley, there's
a trail fork (unmarked June 2015). Keep left and uphill for the BST.
The right fork is a connector that descends 1.1 miles to the Pit
trailhead. It's also known as the Coldwater Canyon trail. Locals use this
trailhead to access the BST. (By parking along the Divide road, you marked
yourself as a tourist. How embarrassing.) A loop from Pit trailhead to the
Nature Center with a road return (see below) is already a favorite.
showing the layout of the area around the Pit trailhead. If you need a
bathroom, it's just inside the fence of the Equestrian Park, 1/10th mile
south on North Mountain Road.
Kudos to the trail crews for their work on the turns.
Switchbacks are well-placed with plenty of turning radius and beautiful
berm. I really liked this northern section of trail and the Pit Trailhead
Typical bermed turn.
The trail continues to climb southbound. As the trail gains altitude, it
runs into an occasional rock outcrop requiring a steeper pitch. Feather the
pedals to get the legs rested, then spin up some velocity and attack.
If you aren't able to clean these first few pitches, you'll be hating
life when you reach the south side of Coldwater Canyon.
The Superfly rests against a rock after
zooming up a short pitch.
The reaches a temporary high point of elevation (5650
feet, 1000 higher than the Pit trailhead) as it turns east into Coldwater
Canyon. Take a minute to look around and recover. The trail just before
the viewpoint has a tough sustained pitch, but it's very do-able. You're
at mile 2 from the Divide Road.
View west at the turn into Coldwater
After a smooth long descent (with an occasional roller) the trail veers back
to the west on the fir-covered southern side of Coldwater.
View to the east up Coldwater Canyon.
The trail now enters a fir forest on north-facing slope as
you climb to the southwest on the southern side of Coldwater Canyon. At
first, it's a mellow climb. You've got 200 vertical feet to climb in the
next 1/2 mile. Doesn't sound tough, but save some leg because there are
some steep spots coming up.
the climb out of Coldwater.
As the trail reaches areas of rock and small cliffs while traversing the
steep hillside, the trailbuilders were forced to make some tough pitches. In
these spots the tread is a bit narrower. Most can be cleaned by strong
riders with appropriate gearing if the trail surface is packed. But will be
painful. I failed on three spots, once because of loose surface and twice
because the legs wouldn't do it.
If you're heading northbound, instead of southbound per this narrative,
there's one brutal loose pitch just outside the canyon. I couldn't clean it
(uphill). But the south-to-north route is good otherwise. So if a few 50
foot hike-a-bikes will ruin your day, ride south-to-north and you'll have
A sample pitch near the top as we head
southbound, about 60 feet of 15-20% slope but firm tread.
The trail now begins the work of descending from 5750 feet
elevation. There will be one series of S turns that are buffed nicely and
should be easy even for early-intermediate riders.
of those beautiful swooping turns. Ben Lomond is hiding behind the dead
tree in the background.
The trail now descends through long straight sections to get back to the
actual historic Bonneville shoreline zone. When the trail hits the older
sections, there will be the occasional rock outcrop and narrower spots where
the vegetation has grown in. In spots the 2015 trailwork has substituted new
broad trail for tricky tight tree-dodging.
Heading southbound, with quite a bit of
descending to go.
At mile 5.8, you'll reach a bulldozed area. Keep to the
left and uphill on singletrack. At this spot, the Nature Center trail
joins the open area from the south on the downhill side, and doubletrack
goes north along the canal.
You'll reach the turnoff to the
Ogden Nature Center at mile 6.3 from the Divide Road. Just drop downhill
and westbound to North Mountain Road. A road return will be 2.4 miles to
the Pit trailhead.
And by the way, a road return for the
entire 10.5-mile North Ogden BST (Divide Road to Ogden Canyon Road) will
be 6.8 miles.
Old narrow trail meets a
new trailcut as it hits the trees.
Miscellany: Shortcut dirt routes between the Pit TH and Divide Road
Some riders shortcut via dirt between the Pit (Coldwater) trailhead and the
Divide road. It's easy to get lost here. I'll help you (get lost). It's a
bit over half a mile.
West route -- may not be available in the future, as home development is starting in the orchard

Go R on DT then at forks go L, then R (turns back southeast). Hard L on DT
then veer R on ST. Hard R on DT again eastbound uphill (narrows) then hard L
on ST to climb to road.
East route. Go around gate and cross creek eastbound on Sunrise. At the fork
in the doubletrack, go L on the broad Parallel Road trail. Keep L where a
smaller trail cuts R uphill. As the trail turns east, fork L to continue
north. Keep straight 1/10 mile, then veer R on ST. At the two-track, make a
hard R. At the BST, fork hard L and climb to the road.
What was formerly an incredible
boulder-bang is now yo mama's cruise.

||Getting there, trailheads listed north to south:
North Ogden Canyon (Divide) Road TH: Exit I-15 eastbound
at the 2700 North (Highway 134) exit. Continue to 1050 East and turn left.
At 3000 North, turn right toward the North Ogden Divide. After leaving the
homes behind, climb about 1/3 mile uphill to a parking area on the right
side of the road N41 18.926 W111 55.908 right where the big power line
crosses the road. The BST is about 100 feet uphill from parking on the
left (opposite) side of the road. (Note: the trail that drops
southeast from the road connects to the North Ogden Divide trail -- which
climbs east up to the Northern Skyline trailhead.)
Pit (Coldwater Canyon) Trailhead: If northbound, stay on
Harrison Blvd until it becomes North Canyon Road. At 4.8 miles, you'll
reach a T intersection on 2750 North. Turn right and park. Take the broad
trail (Sunrise) east, keeping straight (right) at the fork, then
veer R on ST. Climb 1.1 miles to the BST.
From the north, take the 2700 (Highway 134) exit and just keep going east.
The road will narrow and veer a bit south to become 2600. At the T
intersection on North Mountain Road, turn left and go just over 1/10 mile
north then at the T of 2750 North turn right and park.
Nature Center Trailhead: Northbound on Harrison Blvd, go
to mile 2.6 from Highway 39 and turn right into the paved parking. Keep R
at the first trail fork and climb 0.3 miles on the main path to the BST,
ignoring some old connector trails.
Southbound, take 2700 N (becomes 2600) to the T intersection of North
Canyon Road. From here, drive 2 miles south and turn left into the
Jumpoff Trailhead: At Highway 39 (12th street), go north
on Harrison Blvd. Just past 400 North, 1.8 miles from 39, turn right into
a small parking area and find the Jumpoff Canyon trail eastbound. The
trail will split. Take either one to reach the BST 0.7 miles from the
Rainbow Gardens (Ogden Canyon Road) TH: From the
north, take the 12th Street exit off I-15 and drive towards Ogden Canyon
on Highway 39. Just before you'll enter the canyon, as you see Rainbow
Gardens on your right, turn left into a small paved parking area with a
From the south, get off I-15 in Farmington on US-89 and head north. A
couple of miles after you pass under I-84, turn right onto Harrison Blvd,
just as US-89 turns westward to enter Ogden.) Drive north a few miles on
Harrison until you reach highway 39 for Ogden Canyon. Turn right and drive
about 1/4 mile to the paved parking area on your left, just before
entering the canyon.
The trail starts at the eastern end of the parking lot.
In North Ogden Canyon, the BST connects to the Pleasant
View BST just across and uphill on the Divide road. The North Ogden Divide Trail
aka Parallel or Old Pioneer just downhill from the Divide road TH (see multi-track
GPS file) connects to the Southern Skyline and Northern
Skyline trails. At the south end, it connects under the road to the paved Ogden River
Trail and the Ogden BST.
