Mont Blanc climbs see multiple fatal accidents as heat‑triggered rockfalls claim climbers

Two Czech alpinists were killed on July 14‑15, 2026, when a sudden rockfall in the Goûter couloir of Mont Blanc struck their party. The incident follows a spell of extreme heat and drought that has destabilised permafrost, prompting French officials to warn of increased rockfall risk and some guides to suspend summit attempts. Italy responded by temporarily banning ascents of Mont Blanc.

Within the same week, two Asian hikers also died on the mountain. A 67‑year‑old Japanese hiker perished on the Tour du Mont‑Blanc route, and a 69‑year‑old Chinese hiker suffered a ~20‑metre fall at La Flégère, a sector of the Tour du Mont‑Blanc. Rescue teams, including the Chamonix high‑mountain police unit and a civil‑security helicopter, were unable to save the victims. The string of deaths highlights growing safety concerns for the popular alpine trek.
