When the guys at the local bike shop say "This is the
most fun trail I've ever ridden!" you have to pay attention. Of
course, their definition of "fun" includes a tough initial
climb, tricky spots involving rough bone-jarring lava boulders, and a
half-mile plunge that's truly steep and dangerous.
Cranking uphill to the Broken Mesa Rim.

miles north of St. George, the Broken Mesa Rim trail should be reserved for strong
and adventurous riders. The trail can be ridden year-round. The downhill singletrack is 7 miles, with an initial uphill
mile that climbs 600 vertical feet. It can be done as an 8-mile
point-to-point with shuttle, or as a 14.5-mile loop. If you do the loop
option, you'll climb a total of over 2000 vertical feet.
There are frequent switchbacks during the initial
There are a lot of small ledges and thread-the-needle passages through
volcanic rock. The trail is best done with a plush full-suspension bike,
but a skilled rider on a hardtail can still have fun. The lava boulders
create a different type of "technical" than you're used to, so
-- forewarned -- many riders don't like this trail. The lava is also very
good at flatting your tires, so come prepared.
We're up in the fire-scar area, ready to rock some
boulders. Behind me is the "ramp" down toward Washington where we'll
soon be bombing downhill.
To say this trail is "rocky" is like saying water
is wet. There are loose chunks in the trail's riding line, big and small.
There are inconveniently-placed embedded boulders. You will bang your
Even though the trail is rough, you'll want to lock
your rear shock for the climbing. Eliminating pedal-bob makes you much
less likely to strike a pedal as you climb through the rough stuff.
There are great views from this trail. To the north are
the Pine Valley Mountains. On the east are the mesas near Hurricane.

Mountains behind me. Drone shot.
Although the Broken Mesa Rim is a few degrees cooler than
St. George, it gets plenty hot here in the summer. I'd suggest you make
the initial uphill climb in the morning, perhaps starting at the water
tank if you're doing the loop.
This is trail? It's my job to show you exactly why
many riders won't do Broken Mesa!
The trail starts at the northern end of the Red Cliffs
Desert Reserve. The first part of the singletrack climb is fairly smooth,
then it gets steeper and rougher. At 0.5 mile, the trail reaches a doubletrack with a
pipeline on the far side. Find the continuing singletrack trail on your
right, just across the pipeline.
And we're cruising! Eastbound.
Here you'll encounter dead trees from the fire in 2006. The
shrub vegetation has recovered well, and is now beginning to encroach on
the trail's riding line. Here also the climb gets a bit more technical,
with frequent basalt rocks to negotiate.
From time to time, you'll be back in the basalt.
Depending on recent weather and trail maintenance, parts of the trail
will be quite rough with
large loose rocks. If bike control through loose cobble isn't
your thing, reconsider whether you want to try this trail. Check with a local bike shop for
current trail conditions.
Joining the Icehouse Trail.
At mile 1, the trail reaches the Broken Mesa Rim. It twists
through juniper and brush, with more basalt boulders to keep things
interesting. At mile 1.6, the downhill begins. You'll drop onto a broad
treeless mesa as the trail twists towards the edge of the cliffs at
Icehouse is much smoother and straighter. The next
two miles of the ride will only take a few minutes.
Broken Mesa joins the Icehouse Trail
at mile 4.3. From
here, it's a straight shot toward the cliffs west of Washington. This part
of the ride is a cruise.
No stopping now! My Rocky Mountain steps down the
stairs at the top of the mesa.
At mile 6.2 you'll reach the edge of the bluff. Here you'll drop at a 20% grade through the broken
lava. Just hang your
butt way back and aim the front tire straight down the trail. Keep the
bike moving. If the bike hangs on a boulder, bail off the back end.
Did I mention that this part is very rough and very
Reaching doubletrack at the bottom of the hill, you can turn
right to complete the loop. 2.4 miles takes you back to the water tank,
where you turn right uphill to follow the road back to the trailhead.
Alternatively, you can go straight across the powerline doubletrack and
follow the faint singletrack down to Washington and hit the city streets.
Off the mesa. Now we just have to get back to the
Icehouse Trail option:
The Icehouse Trail joins Broken Mesa near
the end of the ride. You can
ride up-and-back from the junction. Or, now hear me out, you can skip Broken Mesa and
instead simply ride Icehouse from the top. Local
riders think the Fun-to-Work ratio is much higher on Icehouse than Broken Mesa.
Wilderness border on Icehouse, with a
stepover for bikes.
To get to the top of Icehouse, go northeast from the Broken
Mesa trailhead turnoff. Drive 2.2 miles, keeping right at the road fork.
Then fork southeast on FR 092 for 1.1 miles on primitive dirt road. The trail starts at the gate, about N37 13.71 W113 32.11.
See the Icehouse Trail page.
Icehouse has 3.5 miles of downhill before it hits Broken Mesa. If you
continue all the way to Washington (see the GPS track file), that's 6.8
miles of downhill cruising.

Getting there: From the St. George Blvd exit of I-15, turn
towards the city (west), then immediately turn right on 10th East. Zero
your odometer here. Take the next right on Highland, then next left onto Industrial Road. Turn left
at 0.7 on Red Rock Road. Keep left at the next
fork, continuing north uphill on Cottonwood Road. (At 3.3 miles, you'll pass a water tank on your right. The return trail for the
loop option comes back here. You can park here and bike up the road if you
want to.) Pavement ends at 3.7. Keep left at the next fork at 5.4. Watch for a sign "Red Cliffs
Mesa Rim Trail" at mile 8.8 and turn towards a fenced parking area
at a stock watering trough at mile 9.0. GPS N 37° 13.451' W 113° 34.197'
Southbound (Washington): Southbound on I-15, exit in
Washington at Exit 10 (Green Springs Drive). Turn right as you exit, then
immediately turn left on Red Hills Parkway. Drive 1.5 miles, then turn
right on Cottonwood Road.
Shuttle option: Leave a car on Buena Vista Blvd, just off I-15's Exit
10 in Washington. As you finish the steep downhill, find ST across the
doubletrack (alternate: turn left on powerline doubletrack, right on ST at second
pole), then work your way downhill through
the golf course and into town.
