Authorities in Delaware said Wednesday that a 59-year-old woman had died after falling from a zip line ride.

According to Delaware Online, the woman was at Go Ape at Lums Pond State Park. The outdoor adventure attraction features a journey through the forest canopy, while you walk on suspended obstacles and take in the views on the zip line.

The woman fell 40 feet from the attraction at around 1:30 p.m., the Delaware State Police said. Paramedics treated her at the scene and transported her to Christiana Hospital where she later died. Her name is being withheld pending next of kin notification.

Go Ape closed immediately following the accident and customers received refunds. Delaware Online reported that staff members appeared visibly shaken after the incident.

"The Go Ape team is deeply saddened by this tragic occurrence," Chris Swallow, director of Go Ape, said in a statement. "Our thoughts and prayers go out to her family and friends and in particular to those who were on the course with her at the time."

Several Go Ape customers told Delaware Online that they’ve always felt safe while riding the zip line and that the company offers training before customers take part on the ride.

Authorities are still investigating the incident.
