This trail is moderate rated at best. Start around 4 PM to stay in the shade on the way down to the canyon floor. After that it's some dirt and sand till you reach the ruins. There's restrooms at the bottom. The ruins are blocked off by a fence so you can't get close, bring a telephoto lens and stand on something to get the fence out of the pictures. Honestly, it's not worth going down into the canyon. Seek out far older and better ruins in AZ where you're allowed to enter and explore, there's plenty. The view from below is rather dull, you'll get the best views from the top and midway on the trail down.
