Key Hiking Messages - Critical Updates and Closures

 

Backcountry Trail Closures and Construction

INNER CANYON TRAIL CLOSURES
Read the news release for additional details.

  • CLOSED — PLATEAU POINT TRAIL from the Tonto Trail junction to Plateau Point. Scheduled to reopen October 1, 2025. Those hiking the Tonto Trail are able to pass through.
  • CLOSED — RIVER TRAIL. Scheduled to reopen October 1, 2025.
  • CLOSED — SILVER BRIDGE. Scheduled to reopen October 1, 2025.
Trail users will need to use Black Bridge through September 30 to cross the Colorado River. Beginning May 15, Bright Angel Trail will be open from the South Rim to Pipe Creek Beach and River Resthouse. There will be no access to Bright Angel Trail from Bright Angel Campground/Phantom Ranch along the Colorado River. Hikers may traverse between the Bright Angel Trail and the South Kaibab Trail via the Tonto Trail.


There are two options to reach the South Rim from the Bright Angel Campground: (1) Hike all the way up the South Kaibab Trail to the rim (7 miles), or (2) hike up South Kaibab to The Tipoff (2.5 miles), follow the Tonto Trail to Havasupai Gardens (4.6 miles), then up the Bright Angel Trail to the South Rim (4.5 miles). This route adds 4.5 miles of hiking with no reliable water source.

These detour routes are also not recommended in the extreme heat of the summer. Hiking up the South Kaibab Trail during the summer months is extremely strenuous and potentially dangerous due to intense heat, minimal shade, and no water sources. Similarly, the Tonto Trail between The Tipoff and Havasupai Gardens offers no water and very limited shade. Daytime summer temperatures in the inner canyon can exceed 110°F (43°C), significantly increasing the risk of heat-related illness.

Hikers should be prepared with adequate water, sun protection, and a realistic assessment of their physical abilities. Attempting these routes during the heat of the day (10 a.m.-4 p.m.) is strongly discouraged.

Hikers and backpackers attempting rigorous distances, such as rim to rim, through the inner canyon are strongly encouraged to be self-reliant to prevent emergency situations for themselves and responders. Be aware that efforts to assist hikers may be delayed due to limited staff, the number of rescue calls, and employee safety requirements.

Taking Care of Yourself

Balance Food and Water

Do not force fluids. Drink water when thirsty, and stop when you are quenched. Over-hydration may lead to a life-threatening salt-balance disorder called hyponatremia.

Restore Your Energy

Eat double your normal intake of carbohydrates and salty foods. Calories play an important role in regulating body temperature, and hiking suppresses your appetite.

Caring for Your Body

Take plenty of breaks and enjoy the view while resting. Resting allows time for proper digestion. If you are hot, cool off by getting wet in creeks and water stations. If you are cold, put on layers and eat food.

If you start to feel nauseated, dizzy, or exhausted, stop and rest. Slowly begin to drink and eat until you feel better. This can take an hour or longer.

Environmental Hazards

Rock Fall

Rock falls are common during or after rain, or during freeze/thaw events. Falls can occur without warning. If you hear or observe rock fall, move quickly away from the area. Do not stop if loose rocks are on the trail.

Flash Floods

Flash floods can occur without warning. Know the weather upstream. If you hear a roaring noise move to higher ground immediately. Face upstream when in or near a creek and have a fast exit plan.

Storms, Wind, and Ice

High winds, storms, and ice can knock down branches. Listen for cracking sounds and move away from the tree. Be aware of trees in campsites. Sudden limb drops can occur even on windless days.

Cold Temperatures

If you are cold, put on layers and eat food. Hypothermia can set in at relatively high temperatures. Make sure to wear weather appropriate clothing at all times of year.

 

In Summer, Avoid the Heat of the Day

Avoid hiking between the hours of 10:00 AM and 4:00 PM.
