In Yukon, the gov't campground are only $12 per night and include free firewood. No other services, other than good views, lake or creek front sites, good scenery, and the cleanest outhouses in the country. With the hours of daylight we have in summer, transport trucks run all night long and we prefer to get away from their noise.
For us, this is well worth the $12 because you get further off the highway where it is quieter, and can enjoy a nice campfire. There's usually a trail or two for walking the dogs too, which is handy.
Most of the campgrounds have picnic shelters too, with tables and firewood for the big wood stove. Nice place to sit around when the weather isn't so nice.
