The Williams Fork Mountains are one of the least known ranges in Colorado. This particular range is located south of Craig and Hayden and north of the Flat Tops. The range has good hiking and climbing, but there are a few characteristics that make it a less desirable range than most of the other ranges in the local area of Northwest Colorado. The range as with several other ranges in the area are pretty unusual since most ranges in North America are aligned north-south instead of east-west as this range is.

The Good

Parts of the range offer good scenery, good hiking and climbing as well as Craig’s closest good rock climbs. There is more wildlife in this area than I’ve seen anywhere in the world with the exceptions of the tropical rainforest and the African savannas. The best scenery in the range is on the southern slopes.

These are the cliffs that some local climbers know as the Hamilton Crags. There is some pretty good rock for sandstone.

The Bad

As with some other Colorado ranges, this range is plagued by private land issues and has relatively few public access points. Most of the south slopes of the range are on public land, but there is a narrow strip (only a few hundred yards wide) which blocks access to much of the area.

The Ugly

The view from the north (including from Craig) of the range is less than inspiring. Unless you are miner, few will be delighted in the gaping strip mines that are feed the power plant that is the lifeblood of the local economy. We all need power and use it, but of course that makes the north side of the range less desirable for hiking and climbing. Luckily the southern side is more scenic. The northern parts of the range are almost entirely private land.

Getting There

The best access road is Castor Gulch which is accessed via County Road 93. CR 93 is reached from Highway 13 about 13 miles south of Craig and just north of Hayden. From Highway 13, you can follow the road a short distance to the Hamilton Crags (rock climbing area) or a ways farther to the boundary of the State Wildlife Area. Public land begins only a short distance beyond the highway, but reportedly the nearby land owner doesn’t like climbers on the crags even though they are technically on public land. Climb anyway (but only on public land), but be aware of the situation and pay attention to the property lines on the BLM maps.

The nameless gulch off Highway 13 between mile marker 79 and 80 also makes a good access route. A short road goes to a pipeline where several game trails begin.

Red Tape

Parking within or driving through the State Wildlife Area requires a habitat stamp. See below for details:

Camping

No camping is allowed in the State Wildlife Area, but you can camp on adjacent BLM lands, though the campsites aren’t great. The best place to camp is where Highway 13 crosses the Yampa River south of Craig. There is a nice campsite for a fee of $5.

When to Go

Late April through early June is best. This is the high desert with some of the widest temperature ranges in the country. In the Craig area, temperatures have varied from 100 in the summer, and -56 in the winter. Summers are warm and can be hot. It can be in the 90's, and there are few reliable water sources in the mountains. Winters are cold, and the winter extremes are ridiculously low here. In the winter months, temperatures of -30 are fairly common, without the windchill.

In early spring, and possibly well into April, everything is a muddy mess. Winter skiing and snowshoeing can be good and there is usually enough snow in many areas December through March.

September and October can have pleasant temperatures as well, but the area is a very popular hunting destination. If you go then, wear blaze orange just to be safe.

Below is the climate summary of Craig, north of the Williams Fork Mountains. The data is from 1894-2007. Craig is at 6300 feet elevation, so expect the temperatures to be fairly similar, but perhaps slightly warmer on winter nights and a bit cooler in summer.
