The most popular and accessible of the corridor trails is the beautiful Bright Angel Trail, a spectacularly scenic 7.8-mile descent to the Colorado River with several logical day-hike destinations. Though steep, long stretches wind down without precarious drops along the edge, making this an excellent choice for families.

Summer heat can be crippling; day hikers should turn around at one of the two rest houses (a 3- or 6-mile round-trip) or hit the trail at dawn to safely make the longer hikes to Indian Garden and Plateau Point (9.2 and 12.2 miles round-trip respectively). Overnight hikers can secure a backcountry permit in advance to camp at Indian Garden, about half-way down and one of the park's three developed inner-canyon campgrounds. Do not hike to the river in one day.
