I think it all depends on the way it is presented in a film. For the most obvious reasons, a scene inside a house needs to add the effect of darkness and usually some sort of pulsating lights effects. Not to mention sounds, etc. Scenes in the woods give off natural effects that give help to that fear factor; Even in a fully sunny day the trees give off an eerie effect of darkness and shadows and as others have mentioned it is very easy to get disoriented and lost in the woods.
