Grand Canyon National Park in Arizona announced updates to its 2025 construction closure schedule as part of the ongoing Transcanyon Waterline project.
The Bright Angel Trail and Campground are scheduled to reopen for public use beginning May 15, following a seasonal closure to accommodate critical infrastructure improvements.
According to a press release, several inner canyon areas, originally closed in fall 2024, remain affected by construction. Although Phantom Ranch Canteen and Lodge reopened on schedule on April 1.
The River Trail between River Resthouse and the South Kaibab Trail junction, as well as Silver Bridge and the Plateau Point Trail between the Tonto Trail West junction and Plateau Point, will also remain closed through Oct. 1, 2025.
The Bright Angel Campground’s large group sites will also remain closed until Oct. 1. However, small group campsites will be available throughout the construction period.
Additional work will include maintenance on the Silver Bridge and the installation of new water pipes and conduit systems, along with excavation for updated waterline and electrical infrastructure on the Plateau Point and River Trails.
From May 15 through September 30, trail users must use Black Bridge to cross the Colorado River. The Bright Angel Trail will be accessible from the South Rim trailhead to Pipe Creek Beach, but there will be no access to Phantom Ranch via the River Trail during this period.
The River Resthouse will reopen, and hikers may travel between the Bright Angel and South Kaibab trails using the Tonto Trail.
Commercial river trip exchanges will take place at Pipe Creek Beach, while private trips will continue at Boat Beach through May 14. Starting May 15, both commercial and private river groups may use either beach for passenger exchanges.
Backpackers undertaking strenuous inner canyon routes, such as rim-to-rim treks, are strongly encouraged to be self-sufficient and aware of their physical capabilities. Emergency response times may be delayed because of limited staffing, high call volumes, and responder safety considerations.
