This is the moment a toddler attempted to cross a stomach-churning 140ft high glass bridge above the Smoky Mountains, before quickly regretting the move and turning back.
Footage captured in Gatlinburg, Tennessee, shows the infant named Forest walk along the iconic SkyBridge, which stretches 680ft across the mountain range, before taking a cautious step onto its glass viewing panels.
The child takes one look down to the valley floor, which lies 140ft below, and makes a swift U-turn.
