San Rafael is one of my favorite places in Utah and it’s always empty! There are 2 main slot canyons: Little Wild Horse and Bell. You can do a loop through both of them or a point-to-point in one. This past trip, we went about 1 mile down Little Wild Horse.
We camped at the trailhead and met this friendly lady from Oregon and had a little campfire with her and her dog 🙂
