How can I play two animactions at once, with one of the animactions looping?

Im making a rpg, and am trying to make a cut scene. I have a walking animation, and I want it to loop, while I make the character move to a new location using a animation I'll create in unity animator window. I would make it move with code, but the char wont navigate over hills and other things in the terrain, it will just walk right through everything.
