Actress/singer Vanessa Hudgens hits the High Sierras with Bear Grylls on this Saturday’s installment of Running Wild with Bear Grylls. During her trek with Grylls she comes face to face with a rattlesnake, evades a boulder avalanche and encounters a dormant volcano.

Hudgens, like many of the fellow participants who hit the outdoors with Grylls, faces her share of challenges. “So Bear wants me to run down the side of this mountain – I don’t feel really good about it,” says Hudgens. “Running down a a mountain that’s full of loose of gravel I feel that’s something your parents will tell you to not do so automatically I’m hard wired to not want to do it but I trust Bear and I’ll give it my best shot.”
