This stunning canyon is 23 mi long, but there is only one trail from rim to base. As a result, a majority of Park visitors clog the north and south rims to see Upper and Lower Falls. To compound problems, the North Rim Road has been closed for the 2008 season for construction, leaving many popular viewpoints reachable only by foot, if at all.
Unless you're up for the six-hour strenuous hike called Seven Mile Hole, you have no choice but to join the crowds on the rims to see this natural wonder. The red-and-ochre canyon walls are topped with emerald-green forest. It's a feast of color. Also look for ospreys, which nest in the canyon's spires and precarious trees.
