Piecing together enough information about these two trails is difficult, so I’ve decided to compile it all in one place! I’ll add pictures soon, hopefully after we check out both of these ourselves. I feel like as Grand Junction native bikers we should know about all the trails in the area and these two are ones we’ve never ridden.
Zion Curtain is out in Rabbit Valley, like Western Rim. It is higher than the Western Rim trail and is longer too. I’ve not heard many say it’s as fun as Western Rim, but I have to assume the views are spectacular. According to the no-longer-updated GJMountain Biking website:
[Zion Curtain is an] Aerobic cross country ride for the junkie who’s ridden most of the Grand Valley and beyond. The moto single track takes you to “Zion’s Curtain” then two ridge overlooks and a pinion graveyard. There’s a fine rolling downhill to bittercreek valley.
STARTING POINT: I -70 to rabbit valley exit. Turn north (right) then take gravel road west over ridge. Take the first left and go to the I-70 underpass.
Ride Description: Start at underpass and go 0.5 miles to well defined ST on left. Cross over DT and go into cool canyon then up the wash. Climb steep hill then pedal to Zion Curtain fence at 3 miles. Although this is the true Utah-Colorado boarder, symbolically this is the end of the promised land to some. Up steadily to the first rabbit valley view (6.8 miles). Nice place to see Castle rocks, Parallel 2 trail and Eastern/Western rims. Head west on wide tract near the ridge line to the fire licked pinion graveyard. Travel uphill to 2nd viewpoint into bittercreek. Roll the downhill until you get to a short steep loose pitch. If packed it might be slide-able. Roll the next section cursing the motocross developers for not staying high and making a cutoff to the DT. Weave your way to a 2nd wash in bittercreek then hike uphill (waypoint 5). At the Kokopelli intersection turn right. FYI 1 mile west on the Kokopelli is the start of the Overlook trail at bittercreek campground. Instead cruise northward to the 1st DT on your right that goes uphill ( point7). More climbing then downhill on loose gravel passing the ST beginning. Here’s a screenshot of the Copmoba map I found of the area: To download the map, click the link below the image.
Most say it’s best to do this ride clockwise. For more information and reviews, visit the Singletracks.com Zion Curtain page.
I thought this trail was more like 30 miles long, but according to Singletracks.com it’s only 23. Here’s their description of the trail:
Scenic trails that mostly follow the Colorado River canyon rim. Singletrack is used by motorcycles, but is surprisingly solid. There are a few junctions along the way that can be confusing, but it you stay along the rim until the back side of the lollipop then you should be fine. However, I recommend getting the regional guidebook to keep you straight. This trail can connect with the Western Rim trail via the Western Rim Connector (see guidebook). A good, solid, scenic ride with mileage and some technical areas.
To get to this ride, drive west on I-70 to the Westwater Mesa exit. The trailhead is there (somewhere). More info to come!
