Chinese Wall Trail is located near Augusta, Montana. The trail is primarily used for hiking.
Best hike in Montana hands down. The trip takes 4 days minimum, mostly because it is to beautiful to not take you're time.
Hard to get there, not a hard hike once you're there. Beautiful. I went from South to north along the main section of the Chinese Wall, ending at Larchhill Pass. Be careful if you do this, you can't camp in the shadow of the wall and after Larchhill Pass, there isn't really anywhere to camp for 3 or more miles. The river at the bottom of Larch hill pass is also dry some of the time, so make sure to bring plenty of water.
But, no better hike in the wilderness.
