This popular national park hiking spot is often spilling over with visitors trying to hike their way through the canyon. So, instead of hiking along the popular Bright Angel Trail, for example, try the South Kaibab Trail—a scenic, ridgeline hike that turns into a backpacking trip if you continue along the switchbacks and take the steep descent down to the river. If it's your first canyon hike, or you just want to take a day trip, avoid an overnight stay and turn around at Cedar Ridge, which makes for a strenuous 3-mile round-trip hike.
