Is it possible to hike down the Grand Canyon?
Yes. Maintained trails lead from both rims to the Colorado River, and a rim to rim hike links them into a single crossing. It is a serious undertaking, though. The route involves several thousand feet of descent and ascent, heat in the inner canyon, and limited rescue options. For a broader look at other trips, see our guide to Grand Canyon backpacking trails.
Always confirm current conditions, trail closures, and water availability with the National Park Service before your trip.
Route and distance
The most common rim to rim route runs from the North Rim down the North Kaibab Trail, crosses the Colorado River, and climbs out on the Bright Angel Trail to the South Rim. Depending on the trails chosen, the crossing is commonly described as roughly 21 to 24 miles. Many hikers also use the South Kaibab Trail to exit, which is shorter but steeper and has no reliable water.
The route passes the Supai Tunnel, Roaring Springs, Cottonwood Campground, Phantom Ranch, and Bright Angel Campground on its way to the river.
Which direction?
Most people go north to south because the North Rim is higher than the South Rim, so there is less climbing overall. Going south to north is also done and is a fine choice if your logistics suit it. In either direction, the last section is a long climb.
When to go
The North Rim is high and has a shorter season, with facilities and the road closing in late fall and reopening in spring. Late spring and early autumn are commonly recommended because summer temperatures at the river can be dangerously high. Check opening dates each year as they depend on snow and park operations.
Do you need a permit?
- Day hike: A rim to rim crossing completed in one day generally does not need a backcountry permit, but the park strongly discourages trying to cross in a single day unless you are very experienced and prepared.
- Overnight: Camping in the canyon requires a backcountry permit. Phantom Ranch lodging and meals are booked separately through the concessionaire and are very competitive.
Check the National Park Service website for the current permit request timing, since it can change.
Where to camp
Typical campgrounds on a rim to rim trip are:
- Cottonwood Campground on the North Kaibab Trail.
- Bright Angel Campground near Phantom Ranch.
- Indian Garden on the Bright Angel Trail.
Permit availability differs by site and date. Splitting the trip over two to four days reduces the strain compared with a one-day push.
Rim to Rim to Rim: time and permits
A rim to rim to rim hike is a round trip, crossing the canyon and returning. Some very fit hikers do it in one day, but it covers roughly double the distance and is a major physical challenge, and the park does not recommend it as a single-day goal. Day hikers do not need a permit, but any overnight stay does. Many people plan it over several days for a safer pace.
Shuttle logistics
The rims are far apart by road, roughly a four to five hour drive. Options include a commercial trans-canyon shuttle, having a friend pick you up, or arranging two vehicles. Book transport early in the season and check schedules.
Water, food, and heat
- Water sources on the trails operate seasonally. Check which are running before you leave.
- Carry a way to treat water and enough capacity to cover gaps between sources.
- Bring salty snacks as well as water to reduce the risk of hyponatremia.
- Start before dawn, and plan to be out of the hottest zones by midday.
Training
Prepare with hikes that mimic the descent and climb, such as long, steep downhill sections with a loaded pack. Trekking poles can reduce strain on knees. Our Grand Canyon training plan shows how to build up to steep descents and climbs. If you are still weighing other routes, our guides to the Escalante Route and Tuckup Trail describe more demanding options.
