Gearing up for an adventure, Reese Witherspoon stepped onto the set of her upcoming film "Wild" in Portland, Oregon on Tuesday (October 22).

The "Legally Blonde" starlet sported shorts, boots and a graphic tee while toting an oversized backpack for the long hike through the wilderness.

Per the synopsis, "Wild" is a story about "one woman's 1,100-mile solo hike undertaken as a way to recover from a recent catastrophe."

Starring along side Reese are Gaby Hoffman, Charles Baker, and Kevin Rankin. "Wild" is slated to hit theaters in 2014.
