Running Wild With Bear Grylls (2014)

Running Wild With Bear Grylls is a reality adventure series that drops celebrity guests into remote wilderness alongside survivalist Bear Grylls, pushing them through grueling terrain with cameras rolling the entire time. The rugged format means clothes come off for river crossings and improvised baths, and the show delivered when Zac Efron stripped down on his episode. CelebMasta has 1 scene from the series capturing that skin-baring trek in full.
