June's Bottom is a slickrock riding area south
of the town of Green River. There are many possible riding combinations,
depending on your appetite for adventure. The simplest ride is a 12
miles loop. For those who are game for a little exploration, I describe
mountain bike routes
of around 15 miles that explore more of the slickrock. You can visit the Green River
both from the cliffs above and from the sand along its bank.
Looking north from the cliffs above
the Green River. Photos and ride description November 15, 2011 by Bruce.
Update with video and some new photos March 20, 2018.
This biking area is
very remote. Come prepared. On two separate rides, I passed no vehicles
going either way, and the dirt areas showed no bike tire tracks since the
June's Bottom is located about seven miles south of Bull
Bottom, another area of slickrock along the Green River.
This is the "trailhead" I describe below. Although you
can't see it, there's a faint doubletrack just behind the log barrier. It
will get more obvious, and more heavily traveled, after about 1/4 mile.
There are three components to June's Bottom. You can combine
them (or skip them) for many nice ride combinations:
1. The main loop. This 11.3 mile loop reaches the slickrock area at its
north end, touching the edge of the sandstone as the ATV path circles the
2. The slickrock. Primo waves of Navajo sandstone. Lots of it. The
highlight is along the edge of the cliffs above the river.
3. The Bottom. At the northeast corner of the loop, you can navigate down
to the river itself.
Sure doesn't look like much from here!
Have faith. There is rock to be ridden here.
The eastern limb of the loop is easier, and is quick for an out-and-back.
Note that the "Classic" ride described below uses the western
limb for both directions. You can easily alter the ride plan to go in and
back out using the eastern half of the loop.
When doing the full loop ride, I suggest a clockwise route. The counter-clockwise
return on the ATV track has some short but ugly loose steeps. Both sides of the loop
have some sand areas, but you should be able to cruise right through.
Handlebar view as we follow the
doubletrack north. You can see a glimmer of the slickrock, with the Book
Cliffs in the distance.
The slickrock is undulating waves of Navajo sandstone. Most of
it is pretty smooth. It slopes gently outward from the red-rock hill to
the cliffs above the Green River. It's half a mile wide and several miles
long. While my ride description uses only the open rock between the
western side of the loop and the descent to the river, there's another
area of slickrock to the west along Three Canyon.
As we leave the dirt layer of the
lower Entrada, we hit Navajo sandstone. At this
point, we can follow the ATV route along the dirt's edge, or head left to
navigate the sandstone wilderness.
From the loop, you can descend two miles to the river itself. There's a
large rock pile at the jump-off point. But you're heading northeast on
faith. You may or may not see an occasional rock cairn. (On-bike GPS
display highly recommended!) Once you get into
the right area, you'll see ATV tracks in dirt between sandstone mounds,
and occasional cairns. Now it's fairly easy to follow the descent down
levels of sandstone until you arrive at the cottonwoods of the river
bottom. The descent is upper-intermediate technical. The return has some
granny-gear grunts with ledges.
When riding the "sampler"
loop route (described below), we head gently downhill toward the Green
River, then turn 90 degrees right to traverse a couple of sandstone miles
toward the descending trail.
Select your ride based on your sense of adventure. This is
definitely NOT a white-paint-spot "ride exactly here" type of
trail. You can go anywhere. Whether intentionally or not. (Note: don't
ride across any cryptobiotic soil! Pick your path to stay on sandstone or
A GPS track
really helps. But I found everything without a GPS track. (My first ride
to this area was 30
miles, but my map below shows only the "bare bones" routes after
crunching the data to eliminate some fun exploration.)
The ATV route along the edge of the
Entrada allows occasional glimpses into the gorge. The mountains on the
skyline are the La Sals.

Sample Ride #1: East-side Out-and-Back to River.
Take the eastern side of the loop, visit the main cliff-top viewpoint on
the way north, then descend to the Green River. Pedal back the way you
To drive there, pass the usual trailhead and park 0.2 miles further east at the road intersection. Start by heading
directly east in the same direction as the road you came in on. Fork left
after 1/4 mile on the doubletrack heading north. The first mile or so
is sandy, and you won't find the riding or the views particularly
For this photo, I've gone about 200
feet off the eastern side of the main loop to find my own viewpoint.
As you get away from the sagebrush steppe, there will be
nice views ahead and to your right. The doubletrack here is firm red dirt
with occasional sandstone. At mile 5.6, a nice option is to fork R on the DT to the viewpoint (0.2 miles
At mile 5.7 from where you parked, look for cairns or signs of
ATV/motorcycle traffic leaving the main doubletrack onto the slickrock.
Turn northeast and ride the slickrock until you
pick up the trail down to the river. The river bank is mile 8.7. Backtrack
to your car to complete the ride with 17.5 miles.
Rubber Ducky Rock. So named on November 15, 2011. On the
eastern end of the loop, this would be on your way back from the East-side
Out-and-Back, or from a clockwise loop.
Sample Ride #2: Simple Loop.
Ride clockwise from the "fence trailhead." On this western side,
only the first 1/2 mile has a bit of sand, then the ATV track firms up. When you hit the slickrock area at mile 3.6, follow the
course of the ATV loop.
You can venture downhill a little onto the
slickrock. Just follow the general loop shape, returning uphill to the ATV
path as you reach the east side. The ride will be around 11.5 miles,
depending on how much zigzagging you do on the sandstone.
Just about anywhere along the loop, you can take a trip out
onto the waves of sandstone for some cruising.
Sample Ride #3: Loop with River Visit.
Start clockwise on the loop as above. As you near the eastern end of the
red dirt, be sure to angle up and find the doubletrack path along the edge
of the rock. Find the big rock pile at around mile 4.7 (see photo -- if
you turn south on the ATV track, you missed it). Head northeast down the rock and find the trail to the river.
View north from the formal viewpoint (marked with a waypoint
in the GPX area file), reached by a short doubletrack from the eastern
side of the loop. Here we see the Green River has cut through the Navajo
and entered the Kayenta sandstone layer.
After reaching the river, head back uphill. But as you hit the flatter areas of sandstone, veer
southwest. Aim for the
edge of the red dirt in the distance. Once you intersect the loop trail,
continue south and complete the loop. The ride will be 15.0 miles.
east as Bruce heads toward the descent down to June's Bottom itself (the
little brown spot you can see along the river's edge).
Sample Ride #4: Classic June's.
Start on the western side of the loop ("fence trailhead"), as though you're going to ride
clockwise. As you reach slickrock at mile 3.6, hug the side of the
mountain to stay on the ATV path. At mile 4.7, find the rock marker (see
photo) and start the descent directly northeast.
This rockpile on the main loop marks a logical spot to start
the descent toward June's Bottom on the Green River, which is about a mile
away. From this point, start angling downhill to the northeast. Note that
cairns may come and go over the years.
Find the ATV path down to the river, marked by cairns. At
mile 6.7, you're at the river. Begin climbing back out. About a mile into
the return climb, just as the slickrock begins to flatten a little, turn
to the west. Make your own path across the rock. Angle a little north
(right) to reach the cliffs above the river.
About half-way into the descent, it becomes more technical.
There are steeper areas with ledges, with stretches of smooth cruising
After you're forced away from the river, continue another
1/2 mile or so west. When you see the edge of the red hill (where you came
in) directly to the south of you, around mile 9.5, turn 90 degrees
uphill. Find the spot where the ATV path entered the sandstone, and head
back home. You'll have to contend with a few short steep spots in the
dirt. The ride will be 13.7 miles.
Last bit of descent. We'll follow this break in the rock
Sample Ride #5: Sampler Loop with Slickrock to River.
This ride is more fun, but it requires a good sense of direction and of
position. Unless you're riding with a GPS display. Then you're golden.
Start the ride on the eastern doubletrack as above. But when you reach
slickrock at mile 3.6, turn left (north) and head as far as you can toward
June's Bottom. It's a sand pit, but I was able to ride 1/3
mile north to explore. To visit the river, turn to the right and
bushwhack. There's no real trail here.
Find a spot to turn eastward, continuing to angle as close
to the river as the stone will allow. You'll reach cliff edge over the
river about mile 4.7. Continue on this course until you blunder across the
descending path to the river. It will be marked with cairns, with
occasional track across spots of dirt between waves of rock. About mile
7.2, you'll reach the river.
Navajo sandstone cliffs across the Green River.
Head back uphill. But as you reach smoother flatter
sandstone, angle off to the left, aiming for the edge of the mountain.
(I'm talking about the red Entrada sandstone hill that was to your right as you traversed the sandstone.) After a
couple of miles, find the ATV path on the red dirt at the edge of the
sandstone, somewhere around mile 9.4. Continue south to complete the loop.
The ride will be around 15.5 miles.
The sandstone area is a wonderland of frozen waves of
sandstone. Great riding that goes on and on.
The riding at June's Bottom is very satisfying. It's a fabulously
fun area. The downside is the 30 miles of dirt road to drive, and a couple
of miles of sand-and-sage to pedal.
The road is fairly smooth and well-maintained, but it will take you about an
hour from Green River. (About the same time as it would take to reach
June's Bottom is remote and only occasionally visited by humans. In the
slickrock area, there's no defined "trail." Plan accordingly!
I'm heading westbound along the edge of the Green River, as
on the Classic June's ride below. Awesome stuff. This is Alcove Bend. You
can barely make out the entry to the slot canyon. The Bull Bottom trail is
on the white rock above the cliffs to the right of the inlet.

Getting there: From US-6, get eastbound on
I-70. Three miles from the on-ramp, exit at the first Green River
off-ramp. Go left under the freeway and continue into Green River. At
Airport Road 1.4 miles from the off-ramp stop sign, turn right (just look
for the "Airport" sign). The road will veer left along the
railroad tracks. Stay along the tracks until another Airport sign turns
you right at mile 1.9, across the tracks. Go under I-70 and drive the
paved road about 2 miles. At the "San Rafael Desert / Horseshoe
Bend" sign 4.2 miles from the off-ramp, turn left onto graded gravel
road. Zero your odometer. Stay on the main gravel road for 20 miles, then
cross the new bridge over the San Rafael River. Note that spot! At 7.3
miles past the river, 26.9 miles since leaving the paved Airport Road,
keep left at the road fork to stay southbound. 1.2 miles later, turn left off the main road on a smaller dirt road. Drive 1 mile on that dirt road.
When you see a short log fence on the top of the rise with nothing around
it, that's the trail. Find a spot to park. The trail begins by going
around the log barrier and finding the faint doubletrack heading north.
An alternate parking spot is near the next road fork 0.2 miles
downhill. The left fork is the route to the counterclockwise loop. If you
ride counterclockwise, head due east on the doubletrack, then fork left
again in 0.2 miles.
