Zac Efron is “Running Wild With Bear Grylls,” which apparently doesn’t require shirts.
Efron got something pretty big: a really high cliff in the Catskills Mountains, complete with a waterfall that the two had to rappel down.
“I can’t believe how high this is,” Efron says in the below clip.
To make sure they committed to their goal, Grylls tosses their backpacks in the river way below. The video stops while they’re still pretty high up, but we’re willing to bet that they probably made it.
The series premiere with Efron airs on Monday at 8 p.m. ET.
