Bryce Canyon this ain''t. However, this is a very bizarre deserted place that is well worth visiting.
The directions on the published routes are outdated because the northern access road is now blocked. Driving straight north on NM 371 from the Grants-Gallup area, watch for the tiny burg of Lake City, after which the road makes a series of major turns right, then left, then right before going straight north again. As I recall, the first road to the right after resuming straight north is the exit. MapQuest calls it road 7295, but am not sure this is how it is marked. There is no formal brown road sign for Bisti Wilderness, but if you look to the east as you approach the gravel road, there is a small sign near the fence paralleling 371 that says "Bisti Wilderness." Turn right, and follow the road a short distance to a crossing with a small sign directing you to turn left, then go downhill and see the well marked parking lot about a mile later on the right, surrounded with large rocks. The road is blocked less than a mile north of the lot.
Absolutes to take with you include water, sun protection, and definitely a compass. This is not a large place so you need only plan for a few hours'' water supply unless you intend to stay longer or overnight.
There is no trail. If you walk eastward up the mostly flat wash, skirting south of the small hills near the parking lot, go about 1/4 mile before entering the first sections of the "wilderness" proper. Some very bizarre hoodoos up to 20 feet high await you, along with a strange mix of reddish, black, dark gray and mostly light gray shale hills.
We encountered a bull and about 5 cows in the middle of the strange landscape, lending a Salvador Dali-like touch to the already surreal setting.
You can easily find your way out using the compass (walk almost directly west). If you go too far north, you will encounter a fence. Follow it southwestward and over the small hills to find the parking lot.
