Finally got around to compiling a trip report for 2012 GCNP hike from south rim. 5 day / 4 night route was: Hermit Trail to Tonto Trail down South Kaibab to Phantom Ranch, then back up Bright Angel. Great route--very doable and good intro to the canyon. We only had to deal with one dry camp, so minimum water hauling even though desert hike. Highly recommend this route if you're looking to plan a first trip there…no "bucket list" is complete without a trip to the Grand Canyon!
