Water Canyon Arch
Water Canyon Arch hangs high above the entrance to Water Canyon, behind Hilldale, Utah. To get there is a strenuous roundabout climb from either Squirrel or Water Canyons, to what i think is called Trail Mountain. A good hiking guide for the trip can be found here. Once on top enough effort will have been spent you might consider, if you are fit enough, a side trip to the White Domes, and making a loop.
I personally enjoy the wildlands of Canaan Mountain more than the hoodoos of the more popular Paria Wilderness. Paria is a lot of driving down long sand roads or cross country across similar sand terrain to pockets of outstanding hoodoo formations. Canaan takes a lot of effort to climb up to but feels to me more like an isolated extension of Zion National Park. And everywhere you go, you eventually run into a huge cliff.
