Bull Canyon Trail
Bull Canyon is a popular ATV route off the Gemini
Bridges Road north of Moab. I'd heard tales of sand and smoky 4x4s
fumes, and I pedaled right past this route for many years. It is worth
doing, maybe not as a destination ride, but as a side dish to another ride
in the area.

The Bull Canyon road starts as a wide dirt/gravel road. Once
it forks away from the Dry Fork Bull Canyon road, it becomes a narrow ATV
track in a wash. The scenery starts to get pretty. There are a few sandy
spots, but I only bogged down once when I didn't pick the right line,
which was fixed by moving the bike 10 feet. On the way out, I rode clean.
After forking to the right off the
larger road, we enter this wash. Not too exciting so far. |

Option: Mag 7 "Tour de Bridge" with Bull Canyon.
My ride recommendation for Bull Canyon is to combine it with bits of the Mag 7
singletrack for a tour of the top and the bottom of Gemini Bridges. Here's the plan: Up
Little Canyon Singletrack to the Bull
Canyon road, visit the arches from below and double back. Resume Little
Canyon ST, continue on Arth's Corner to Gemini
Bridges. Visit the arches from above. Now head back down Arth's and Little Canyon. See
the mile-by-mile ride directions below.
Heading uphill on the Little Canyon
Singletrack, an excellent way to ride Bull Canyon. |
Option: Two Tortoise Loop with Bull Canyon add-on.
Another option is to hit Bull Canyon as an out-and-back add-on to the Two
Tortoise Loop. If done from the bottom of the Gemini Bridges road,
that ride is 20 miles; 23.5 if you go all the way up to the turnaround in
the upper canyon. If you do only the "local loop" of Two
Tortoise Rock, it's about 10 miles.
A bit further up Bull Canyon. |

Option: Classic Bull.
The "classic" Bull Canyon ride is a simple dirt-road crank up
the Gemini Bridges road to the Bull Canyon road.
Or, as is more often done, as an out-and-back off the Gemini Bridges road
when you're riding it top-to-bottom as a shuttled ride.
The canyon gets deeper. The rocks tend
to keep this area cool for longer in the day. |
From the Gemini Bridges road, Bull Canyon starts out wide
and smooth. After 0.1 mile, you'll pass the Little Canyon Singletrack
crossing. At 1.2 miles, you'll pass the Two Tortoise Rock trail coming in
from the left side.

bridges. My Superfly 100 is all alone. |

At 1.6 miles from the Gemini Bridges, there's a critical
fork. The broader fork veers slightly to the left, and continues to the
Dry Fork of Bull Canyon -- not the one you want. Bull Canyon forks 90
degrees right and promptly drops into a wash. You might think you took the
wrong fork until you see carsonite trail posts later on.
Starting the hike to the arches. The
Gemini Bridges are straight ahead to the "fluted" wall, then to
the left. |
The walls of the wash become deeper and become tall cliffs
of Wingate sandstone. There are a few sandy patches, but with a 29er, 2.1
tires, and a bit of speed I could ride them all. There aren't any tech
sections. It's just straight-ahead dirt-road riding while you enjoy the
scenery.
At 3.2 miles, you'll reach the hiking trail to Gemini Bridges. I didn't
see a "no bikes" sign, but the carsonite marker showed only a
"hiker" icon. So I assume you're NOT welcome to ride up the
hiking trail. The trail is 0.6 miles long, arriving at a spot under
the arches.

I had the whole canyon to myself on the way in. It was cool
and peaceful. As I came back from the arches, a whole herd of ATVs had
arrived. By the time I returned from the dead-end in the upper canyon,
there were 25 vehicles in the parking area and more arriving. Early
morning is definitely the time to ride.
As I return from the bridges, my bike
has company. |
The usual turn-around spot is the foot trail to below Gemini
Bridges. But the trail continues another 1.6 miles up the canyon then
dead-ends. Just
before the end, a side path goes down into the canyon to old mines. It
also dead-ends. So stay high and enjoy the view at the end.
On the dead-end upper canyon, about a
mile from the bridges trail. |

|
 |
Turn around and bomb back down the ATV track. Few vehicles
venture beyond the parking area for the bridges trail, so you've got the
canyon to yourself.

turn-around. |
Once you're back on the main Bull Canyon road (after
rejoining the Dry Fork road), consider a variation on your ride. Two
Tortoise Rock and the Little Canyon Singletrack are alternate ways down the
mountain.

skyline is the Gold Bar Rim area. |
