The walls of Jericho are an incredible site to see if you are willing to make the backpacking adventure to them. The hike in takes only about an hour and is all downhill. Park at either the Alabama or the Tennessee trailhead (make sure not to park at the horse trailhead earlier on the road) and descend down into the canyon. When you reach the bottom of the trail and cross a river there are several campgrounds that you can set up at. After getting settled keep following the trail back into the canyon and you will get to the first waterfall/pool. Don't stop there though cause the real view is the waterfall at the back of the canyon that takes a little scrambling to get to. While there recently with my wife we spent 2 nights camping at the horse campground and spent our full day doing a loop hike into Tennessee. The only thing you have to be cautious of is it can get pretty muddy if it has rained heavy recently. I would suggest going in spring cause that is when everything is blooming and so beautiful.
