Overview
- Two separate inner‑canyon incidents on June 12 and June 16 resulted in three deaths; the victims were a 72‑year‑old man on the South Kaibab Trail and a 67‑year‑old man and 68‑year‑old woman on the North Kaibab Trail, and all were transported to the Coconino County Medical Examiner.
- The National Weather Service issued an Extreme Heat Watch for the Grand Canyon area forecasting parts of the inner canyon could reach or exceed 110°F, raising official concerns about safe hiking windows.
- Park rangers say inner‑canyon temperatures can be 15–30°F hotter than the rim and strongly advise visitors to avoid inner‑canyon trails during peak heat hours, carry all needed water, and plan hikes for cooler morning or evening hours.
- Responders provided rapid ground and aerial support but found all three hikers deceased on arrival, and park officials say an investigation into the June 16 incident is ongoing.
- The recent deaths follow other heat‑linked incidents this month and highlight recurring summer risks that could increase rescue demand, prompt stricter public advisories, and change how visitors plan trips to the canyon bottom.
