Default sat imagery, plus contour lines, plus mapbuilder overlay works wonders and I find preferable to stock USFS/NPS maps since you get better info from sat imagery than from their "green area, white area durr".
You can hit the print to PDF button and you can set it to 1:24k for detail maps and higher for area maps.
Go to a kinkos and print it out on rite-in-rain type paper on A4. They'll do 12x18", but that requires either a pro account of personal tech ability to make your own maps in photoshop/gimp.
I usually spend an hour or so dialing it in via gimp and printing to 12x18, but that's more involved.
