Don't throw rocks in glass houses!
Overview: This is a hike to the Windows, taking in turret arch, and continuing on the "Primitive" trail to make a loop.
Warning: Desert hiking is hot, take some water with you.
Hike: From the parking area, begin walking towards the windows and turret arch on the main (non-primitive) trail. At the trailhead there are some educational billboards that explain how arches are formed.
After a short distance, take the spur loop to look at Turret Arch. Continue around the spur loop until you are back on the main trail. Take the trail up to see the north window you passed slightly, then double back and go up to the south window. You can now take the signed primitive trail, which is marked by rocks, around the slickrock to see the windows from the other side. Since you have to return to your car either way, might as well finish with another half a mile on the back side as opposed to the front.
The main trail is not paved but has steps and is all gravel. The primitive trail consists of walking on slickrock between rocks the mark the edge of the trail.
Note: You can leave your car parked here and walk over to do Double Arch, or you can do the lazy American style of getting back in your car, driving 20 seconds, and parking on the other side of the parking area to save walking that extra hundred yards.
