I've let Parks Canada tell you how great they are, but we have some first hand experience.
Last year we got to camp in Bruce Peninsula National Park and celebrate Christmas in Jasper National Park.
It took some convincing to get the whole family into the woods and into a tent, but they haven't stopped raving about it since. CantStopWontStop has even brought it up in the midst of the deep freeze. Plans have already been made for this summer.
If a tent is too much for you, there's usually some hard roof accommodation options.
Whether you are hiking, biking, skiing, sledding, or just plain relaxing these are some of my favourite spaces in the world.
But don't take my word for it. Parks Canada is making it easy this by giving away annual parks passes for free. Get out there!
