If R2R2R is not enough of an adventure for you, and you are experienced in climbing technical terrain, this is the route for you!
Buddha Temple is an aesthetically magnificent feature located on the north side of the Colorado river. The journey has it all from incredible views, off trail boulder hopping, prickly pear dodging, technical rock climbing, and best of all: solitude! Buddha is truly a testpiece for anyone who considers themselves an adventure runner.
The route starts at the South Kaibab Trailhead and from there heads down to Phantom Ranch. From there find the unofficial Utah Flats trail, this leads to Phantom Creek. From here its all off trail. Head up the canyon between Shellbach and Buddha. Before reaching the saddle you will encounter a few 4th class scrambles. From the Shellbach-Buddha saddle head north around the Supai walls. Eventually you will find a fixed line over 5th class terrain. Once up on the Hermit shale, contour around Buddha to the south. The southeast face should be obvious as it is the path of least resistance on that aspect. Enjoy the climbing! From the summit head back the way you came!
Route stats: 32 miles - 16k gain - 300ft of 5th class climbing
