You may think the idea of a 50-mile dayhike across Zion National Park is too far past sane for your taste–or that it sounds like a bit of inspired genius. Either way, this gallery of photos from a north-south traverse of Zion may inspire you to dayhike, trail run, or backpack all or part of it, and spring is an ideal time for this adventure. Read my story and watch a video about that one-day hike, or see my story, photos, and video about a family backpacking trip along part of this route.
