Walt goes back to the cabin to retrieve at least some of the money because he has a big bag of it with him when he buys the gun and changes cars. But the authorities know his proximate location and will be using all means to find him. My best guess is that he pays someone with money from the box he was going to send to drive him back to the cabin and out of the state. But getting by the dragnet seems improbable as he is in the middle of nowhere with few roads easy enough for the authorities to roadblock.
