You can also use National Geographic's "Adventure Paper". This is a (supposedly, never actually tried it) water-proof tear proof paper designed for inkjet printers:

National Geographic sells it since they recommend it to people who use their "Topo!" product (Topographic maps of the US) which is an excellent product btw. My husband and I have used it to produce routes and with Topo! Streets & 3D Views, you can use it to track via roads. What's pretty cool is that you can get an elevation profile so you can see how bad a route is before going out on it.
