Assumes a 2-3 night corridor backpacking trip on the Bright Angel, South Kaibab or North Kaibab trails in spring or fall for a small group holding a backcountry permit. Covers the permit lottery, heat and water logistics, the no-fire rule and critter-proof food storage. Summer trips need pre-dawn starts, more water and salty food; winter trips need traction devices. Check current trail and water closures before you leave.
Check before you go
- Backcountry permits run through a Recreation.gov early-access lottery (two-week window ending the 1st of the month, four months ahead) with remaining dates opening on the 1st; $10 application plus $15 per person per night below the rim (NPS, as of 2026).
- Corridor campgrounds allow 2 nights per campground per hike (4 nights Nov 15-Feb 28) and 7 nights max per use area; the permit must be in the trip leader's possession.
- Inner-canyon temperatures often exceed 105 F in summer; do not hike between 10 am and 4 pm, eat double your normal carbohydrates and salty food, and drink to thirst to avoid both dehydration and hyponatremia.
- Corridor water depends on the Transcanyon Pipeline and shuts off with little notice. As of Sept 28, 2026 all inner-canyon water was off and Phantom Ranch, Bright Angel and Cottonwood campgrounds were closed by flash-flood damage; check Key Hiking Messages first.
- Wood and charcoal fires are prohibited (stoves only); burning, burying or leaving toilet paper is prohibited, so pack it out.
- Every corridor campsite has a metal food storage can and pack pole; ravens, ringtails and squirrels raid unsecured packs. Pets and drones are prohibited below the rim.
- Climbing out gains about 5,000 ft; plan on twice as long to hike up as down. Hypothermia and heat illness have been treated on the same day.
