So, my friend and I are going on a trail ride on Friday. We're meeting at the trailhead down the road from the stable I board at (I'm riding down there because it's about half a mile and she's trailering in because she boards about six miles away). I know the trail we will be ultimately taking, but I'm not sure how to get there from the trailhead (when we ride out from the stable, we take a "shortcut" through a neighborhood south of the trailhead that's right across the street from the stable).
Does anyone know where to get good, comprehensive maps of trails? We will be riding in the Granite Mountain Wilderness Area near Prescott, Arizona (leaving from the Williamson Valley Trailhead). Part of the problem is that I don't know the trail numbers or names in the area and there are probably a good half dozen trails just in the area we'll be in.
