Bear Grylls has spent years traveling the world -- and occasionally, he brings along some notable company. Ahead of next week's episode of Running Wild With Bear Grylls, CBR can exclusively share a clip featuring Danny Trejo and Grylls exploring the Arches National Park in Utah, where Trejo must perform his own gravity-defying stunt.

In the next episode, Grylls is accompanied by Trejo (who is actually the oldest guest yet to tag along with Grylls in his adventures) as they explore the Moab Dessert, where they find themselves atop a massive mountain. "Where's my stunt guy," Trejo jokes, looking at the mountain he's about to scale down -- backwards.

Currently in his sixth season, Running Wild With Bear Grylls takes him across the globe with a celebrity guest in each episode. Already this season, which began airing in March, Grylls has explored the Italian Dolomites Mountain alongside Falcon & Winter Soldier star Anthony Mackie and journeyed through the Icelandic highlands with Brooklyn Nine-Nine's Terry Crewes.

According to the episode's official synopsis,

Bear Grylls takes LA icon and living legend Danny Trejo out into the staggering peaks and steep canyons of Arches National Park in Utah. Under scorching temperatures, Bear and Danny climb massive boulders and traverse sheer cliffs in order to reach their extraction. Even Danny's days in prison can't prepare the show's oldest competitor as he squares off against the intense heat and treacherous obstacles of Mother Nature herself.

Running Wild With Bear Grylls airs on National Geographic. The next episode of Season 6, "Danny Trejo," premieres Monday, May 3 at 9:00 ET/PT.
