Bob's Walk

Bob is hiking. He is 1 km from a river and his campsite is 3 km from the river.
If he walks directly to the river he is 2 km from the point where he would end up if he walked directly to the river from the camp site.
How should Bob walk if he needs to go to the river to get water, then return to his camp site if he wants to travel the minimum distance?
