Zac Efron Facts
How well do you know this Hollywood hunk?
Zac Efron loves a good adventure. When he’s not showing off his dancing skills, or making out with Michelle Rodriguez in Italy, he’s jumping off cliffs with TV host Bear Grylls!

A shirtless Zac appears on the premiere episode of Running Wild with Bear Grylls, a reality show which takes celebrities to remote locations for 48 hours of thrills. Sounds terrifying!

For his two-day adventure, Zac heads to the Catskill Mountains to jump off a cliff. In the clip below, you’ll see Zac and Bear repel off a cliff that just looks way too high! Zac even notes, “I can’t believe how high this is.” Check out the sneak preview of the episode to see how Zac deals with his nerves.

The 26-year-old actor isn’t the only huge celeb making an appearance on this adventure show. Channing Tatum and Ben Stiller will each appear on an episode of the series. We can’t wait!

Be sure to check out Running Wild with Bear Grylls when it premieres Monday, July 28 at 8 p.m. on NBC.
