Plenty of parking off the highway for cars, campers or 18 wheelers.
You can drive up the road with a 2 wheel drive pickup or other medium clearance vehicle, or walk up the road from the parking area. It is just short of 0.2 mile from the cattle guard to the cache.
When you get to the "Behind The Rocks" trailhead sign, turn off the road to your left. You will be very close to the cache and that is a place you can turn around. The 29 mile jeep trail begins there. Descriptive information is provided on the sign. Look back to where you came from and you get a great view of the La Sal Mountains and the very upper end of what is called Spanish Valley -- once known as Poverty Flats.
The cache contains a log book, pencil, some swag, and until someone finds it, a gold FTF geocoin.
