If you hold a corridor backcountry permit at Grand Canyon for this fall, the campground on it is closed and the park has not said when it will reopen. Work out your refund position this week, because the nightly-fee refund window shuts 30 days before your start date.
What the park closed
The September 3, 2026 release expands closures after the August 29 flash flood, which the park says “caused significant damage in Bright Angel Canyon and the Phantom Ranch area.” Effective immediately it closed the South Kaibab Trail below the Tip-Off and the Bright Angel Trail below the Tonto Trail junction.
Already closed after August 29: the North Kaibab Trail, Cottonwood Campground, Phantom Ranch, Bright Angel Campground, and both the Black Bridge and the Silver Bridge.
That is the entire corridor. With both bridges closed along with the trails on either side of the river, a rim-to-rim crossing is not available. The one exception in the release is river trips, which “may continue to conduct exchanges at Pipe Creek Beach along the Bright Angel Trail.”
On reopening the park is blunt: “There is currently no estimated date for reopening these areas. Reopening decisions will be based on conditions on the ground and the park’s ability to safely restore access.”
The part that costs you money
The park’s backcountry permit page, read September 8, 2026, sets the fees at “$10 per permit or lottery application plus a nightly charge of $15 per person for all below rim areas and $4 per person for all above rim areas.” Then the line that matters: “The lottery/basic permit charge is non-refundable. The per person or stock animal nightly charge is refundable until 30 days before permit start date.”
Read against a closure with no end date, that is an awkward pairing. A four-night corridor trip for two people is $120 in nightly fees. Thirty days before an October 8 start date is today.
We could not find a park statement waiving or extending that policy for this closure, and we are not going to assume one exists because it would be reasonable. Call the Backcountry Information Center on the South Rim and ask directly. The park’s main number is 928-638-7888.
What to do this week
Find your permit start date and count back 30 days. If that date is close, make the call now rather than waiting for a reopening announcement that the park has explicitly declined to forecast.
If you were planning a corridor trip and had not yet applied, plan around the closure rather than through it. Rim-country and above-rim itineraries are unaffected by these particular closures, and at-large camping outside the named use areas is a different permit conversation.
One more thing worth saying plainly: this is post-flood terrain with damaged trails, bridges and utilities, and crews are working in it. A closed trail here is not a formality. Whatever a map, an app or this page says, the posted closure and what a ranger tells you at the trailhead is the rule.
