In November 2025, contractors for the Department of Homeland Security installed concertina wire at the U.S./Mexico border at the southern terminus of the Arizona National Scenic Trail. This prevents trail users from accessing Border Monument 102 — the traditional “start” or “finish” of the AZT. In the interest of safety, please do not attempt to cross the wire for a photo at the monument.

Border wall construction activities continue west of Coronado National Memorial, including blasting to make gravel for concrete. Additional steel wall construction is not planned at the Arizona Trail’s southern terminus until August of 2026, where trail closures may be necessary to protect trail users from construction activities.

Please check back for updates.
