16-year-old American tourist dies after falling more than 90 metres from the Switzerland Trail

According to Swiss authorities, an American teenager died after falling more than 90 meters during a sightseeing tour.

The 16-year-old girl was hiking with a friend and her family in Valais just after 10:30 a.m. local time on Sunday, June 9, when she “stumbled” and fell about 100 meters (328 feet) down an embankment, according to a French-language press release from Valais police, which was translated by both CBS and NBC News.

According to police, the group was hiking on the popular Gorges Mystérieuses hiking trail in the Tête Noire Gorge near the Trient River when the incident occurred.

According to NBC News, “two helicopter crews, two regional rescue teams and emergency psychologists” were on the scene. Rescue workers eventually found the teen’s body in a riverbed below the trail. Authorities have not released her identity.

According to police, the friend’s father was also rescued after he got stuck on a rock face while trying to save the teenager. He was unharmed.

The investigation into the incident is ongoing. It is unclear why the girl tripped and went off the path.

Created in 1884, the Tête Noire Trail includes 120 kilometers (74.5 miles) of walkways and bridges leading to the bottom of the gorge, where visitors can find waterfalls and a hidden grotto, according to the Swiss government’s tourism website.

The return route is a centuries-old international trade route that connects Martigny in Switzerland and Chamonix in France.

Sunday’s incident occurred in the same canton where another American teenager died in April when the 15-year-old was caught in an avalanche near the Swiss Alpine ski resort of Zermatt.

Two other people were reportedly killed in the incident in April and a 20-year-old Swiss man was seriously injured.
