Geyser Pass is easy to ride, with only a couple of very short tech spots involving rocks and roots. It's aerobically easy as well, although flatlanders -- and aging website authors -- may suffer effects of the altitude when the trail turns uphill.
The trail starts at the Geyser Pass trailhead at 10,500 feet elevation. There's a bathroom and trail kiosk, with parking for around 10 vehicles. The pass is also the drop-off point for the commercial shuttle vehicles from Moab.

When riding the singletrack as part of the Whole Enchilada , you'll bypass some primitive and steep dirt road that formerly was the only route to the Burro Pass trailhead.

But you can also, should you be inclined, do Geyser Pass as a three-mile loop ride (by returning to the pass via the doubletrack), or as a figure-eight of just over 6 miles when combined with the shorter version of Moonlight Meadows .

From the trailhead, you have two options to find the trail. You can go to the right of the kiosk, then veer left onto the Geyser Springs road (071).
Most riders will hop on the singletrack between the toilet and the kiosk. This will take you past a picnic table before dumping you onto the doubletrack after about 100 yards.

You'll quickly come to a fork in the dirt road 0.1 miles from the trailhead. The right fork is FR 071 heading east. This is theroute, connecting by dirt road to the Burro Pass trailhead. Instead, keep left on FR 243. The fork in the road is marked with a nice sign (as of 2015). Just uphill along the side of the left fork, you'll also see the little "WE" sign that marks the Whole Enchilada route.

Pedal on a bit uphill. In less than 100 yards, you'll see the singletrack (marked with the "WE" sign) branching away from the doubletrack on your right. The trail begins a gentle climb. You'll gain about 150 vertical feet over the first mile of trail.

You'll traverse meadows (and dodge the occasional cow -- or cow pie) with views of the surrounding mountains. The trail will pass through groves of aspen (with a few roots to bang across) as it skirts stands of fir. To your left and slightly behind you is Haystack Mountain. Straight ahead is Mount Tomasaki. In another mile or two, the Burro Pass trail will take you north across the saddle between these two peaks.

The occasional trail boulders (and the mountains they came from) are a form of granite called diorite. (The La Sals were built by an igneous intrusion. Liquid rock pushed up and displaced the overlying sedimentary layers.) There are a couple of rock gardens you'll need to navigate, but they're not too tough when ridden west-to-east.

After a mile, the trail will begin to drop into the little canyon south of Burro Pass. You'll lose 250 vertical feet. When you reach a doubletrack heading straight uphill, turn left and climb. You're now on segment 2 of the Whole Enchilada The Burro Pass trailhead is on your right, about 200 feet uphill.

If you're doing a loop or figure-eight ride instead of the Whole Enchilada, drop to your right downhill when you reach the doubletrack. At the Geyser Springs road, fork right and climb back to Geyser Pass. If you're doing the little Moonlight Meadows loop for the figure-eight ride, turn left uphill when you hit the doubletrack fork just north of the trailhead. You've been at this spot before. But instead of veering off onto the WE singletrack, keep left on the doubletrack for about 100 yards before forking left on the Moonlight Meadows singletrack.

Getting there, Geyser Pass TH:
On Moab's Main Street, head south on US-191. Zero your odometer at Center Street Center Street and drive 8.2 miles. Turn left toward Ken's Lake - La Sal Loop Road. At the T intersection 1/2 mile later, turn right. Stay on the paved La Sal Loop Road to mile 20.6, then turn right on gravel Geyser Pass road. After several miles the road narrows to a single lane. Drive 8 miles on Geyser Pass road (to mile 28.6) until you see a bathroom, kiosk, and parking on your left with a road fork straight ahead.  This is Geyser Pass (N38 29.122 W109 13.940).
East end at Burro Pass TH:  As you pass the Geyser Pass parking area, go left (you should see a "Burro Pass 1.2" sign as you curve around the fork), then keep right at the fork that immediately follows. 1.2 miles later (mile 29.8) turn left off the main road on an eroded doubletrack climbing steeply up the mountain, with a sign "Burro Pass TH" (N38 29.408 W109 12.906). Go 1/2 mile up the mountain (4-wheel drive strongly suggested here) and park on the right side where the DT disappears into some fir trees. The Geyser Pass trail is 200 feet down the doubletrack.
