Upper Pass Creek is part of an extensive trail network near Cottonwood Pass. The trail is popular for camping since it is conveniently located within feet of Cottonwood Pass. However, those looking for solitude will not find it in the several campsites along this trail.
The trail has several different access points, and your experience on this trail will vary depending on which section you drive. Although most of the trail is relatively easy and accessible, even with a camping trailer, two sections earn the difficult rating.
On the west half of the trail is a tight and washed-out section that requires a stock 4x4 that doesn't mind pinstripes. On the east end of Upper Pass Creek is the true challenge requiring a lightly modified, high-clearance 4x4 vehicle with a low range and an experienced driver. This section switches from dirt to rock and is tight in the trees, with no room for choosing lines. Rocks up to 20 inches must be driven over before this trail ends just below Cottonwood Pass.
