If you want to go to 13A, it is a 4 1/2-5 hour drive from Las Vegas. 13B is a bit closer and you access it from St. George. To get into 13A, you'll turn south just before the big green water tank just east/south of Colorado City. Find the grocery store and when the road turns from asphalt to dirt, keep going. Go right where it "T's" and then you'll eventually turn south (its pretty obvious where to turn south) onto Clayhole Road. That'll take you all the way down to the bottom of 13A. You should find bucks in Toroweep Valley, and along road 1001, out by the rim that separates 13A from 13B. Have fun, it's awesome country.
