A woman plunged 160 feet to her death from the top of a remote waterfall in front of her horrified children on Mother's Day, The Sun reported.
The woman, 58, was crossing Windin Falls in Cairns, Far North Queensland, Australia, when she tripped in a natural infinity pool and was knocked out.
Sunday afternoon's misfortune was seen by terrified witnesses who described how the force of the water threw the woman to her death. "She was getting pushed back and forth... the water was like rapids," a witness told the Daily Mail.
Windin Falls has a natural infinity pool at the top of it, and thousands of people endure the one hour and a half trek to take selfies at the scenic spot, which overlooks a lush rainforest valley.
A fellow hiker called police but it took a rescue helicopter, officers on the ground and drones around three hours to find the woman's body at 4 p.m.
The water's current in the infinity pool was particularly strong following days of non-stop rain, those at the scene said.
"We activated members from our Atherton and Malanda crews and actually took an all-terrain vehicle in through the walking track that leads to Windin Falls," Peter Rinaudo, State Emergency Service (SES) area controller, told ABC News.
It was not immediately known whether the woman was taking a swim in the pool or posing for a photo before she slipped to her death.
The Queensland Police will prepare an incident report for the coroner.
