The Bright Angel Trail is steep and very long. It covers one vertical mile in elevation change between rim and river. It is a 7.5 mile long hike. The trail is well-maintained and wide trail and does not contain any difficult “hiking moves.” Some conditions that significantly increase the difficulty of this hike include: extreme temperatures (Summer temps exceed 100° F and sometimes exceed 115° F), and carrying the extra weight of your backpack/clothing and water significantly increases the stress and amount of effort exerted.
Average hiking time is 6-8 hours but your hiking time will be dependent on your fitness level and the weather (mainly extreme heat).
