Just found this thread when searching for the exact same thing. I was going to start my own thread, but figure I'll revive this one since I have the same question.
My wife and I are heading to the Canyon this weekend from Orange County just for 3 days including driving. We are planning on going to the South Rim, but could do North. Planning on doing some hiking (suggestions welcome). We are taking the Jeep and I would love to do some short trails. Ideally some that lead to a cool outlook, or hiking trail. I do have a pretty capable rig, but will be traveling solo so I don't want to risk getting stranded on any trails.
Any advice would be very much appreciated!!
