Zac Efron goes on a wild experience with Bear Grylls

There's one thing better than looking at Zac Efron scale down a cliff - Zac Efron scaling down a cliff shirtless.

In an episode of Running Wild With Bear Grylls set to air next week on July 28, the actor teams up with Bear Grylls to go through an adventure in New York's Catskill Mountains.

Just before they scaled down the cliff, Grylls told Efron to remove his shirt and stuff it into his backpack so that they'd have dry shirts once they made it down.

The sight of the two guys with chiseled abs was just as amazing, or maybe more, as the view that surrounded them.

It was evident that the 26-year-old's mind was clearly nervous about having to do such a dangerous stunt from a precarious height.

In another preview scene, Efron had to get to the other side of a mountain by pulling himself across on a rope. At one point he nearly fell off, but thankfully made it in one piece.

"We reached out to him and he kindly said he was a fan of the show and that he was in 120 percent," Grylls told People. "He asked for the biggest, baddest adventure and it was an honour to oblige."

The clips were a few short sneak peeks released of the episode.

Hopefully, the episode will be filled with more of what we want - dangerous stunts and shirtless men.
