Channing Tatum gushes about the “once in a lifetime” experience he has with adventurer Bear Grylls in a new preview clip from the next new episode of “Running wild with Bear Grylls.”

The NBC show sees the host take celebrity guests on all sorts of extreme adventures. He’s already explored Scottish caves with Ben Stiller and rappelled down a waterfall with Zac Efron.

With Tatum, Grylls goes to Yosemite National Park to do a little hiking, rappelling and diving… out of a helicopter. “That was by far the most insane thing I’ve ever done,” Tatum says.
