Williams Pass is proof that trails can be reopened once they have been closed. The trail was closed for 12 years and reopened again in 1997, though it is only open for the month of August each year (weather permitting). It is a short trail filled with challenges and awesome scenery.

Though you can start at either end, the trail is a bit more fun and exciting if you start at the west end near the Alpine Tunnel on Hancock Pass. The trailhead is barely noticeable, and just south of the Palisades. It is marked with a brown sign, and you can easily see the seasonal forest service gate just a few yards from the Hancock Pass trail.

Williams Pass starts as a climb over big rocks, and it can be challenging right away. You climb up to a grassy trail and around a switchback, and soon you find yourself in a large meadow. In front of you, there are rocks made red by the water crossing over them. Have fun on these wet rocks as you climb.

You can see Williams Pass almost straight ahead, a saddle between Mount Poor on the left and Mount Arps on the right. Williams Pass marks the continental divide, and this is where you're headed.

The red rocks soon end, and then the trail turns to soggy rocks that are often muddy and loose. Many of the big rocks are unavoidable, because the trail is narrow. There is thick brush to either side. Be sure to stay on the trail at all times.

This rocky climb is a lot of fun, and finding the big rocks in the trail can make it quite challenging. The pass itself is marked with a 4x4 post, and the rocky section has ended.

Just past the pass, however, is the mud. This mud changes from year to year, but it is almost always there. It can be deep and sticky, and the ruts themselves can be very deep. Be sure to stay on the trail and stay in the mud.

After the mud, you start downhill. This side of the pass is bumpy in places but fairly easy. You circle around and come to the inner gate, and then soon to the final gate.

Between the inner and final gates is a hiking trail that provides access to the Alpine Tunnel from the other side. It is a steep hike, but not particularly rough. The final gate is often open when the initial and inner gates are still closed, to allow access for hikers.

Williams Pass is a rare treat because it is not open for very long every year, if at all. It makes a great loop with Hancock Pass.
