At 66' 33' N, a bleak stretch of treeless countryside marks the beginning of the Arctic Circle. Here you'll find Polarsirkelsenteret, right on the line at the Saltfjellet-Svartisen National Park. Here you can build a small cairn as evidence you passed the circle. You can also get an Arctic Circle certificate to show the folks back home, and there's a post office selling postcards with a special Arctic Circle seal.
