Heading south from Missoula MT, we took HWY 12 to cut west across the middle of the state, through Lolo National Forest. On the tip of a really nice waitress in Missoula, we took this route and stopped at a tiny trail on the side of the highway for “Weir Hot Springs” which you wouldn’t even notice unless you were looking for it. It ended up being a really small hot pool made of rocks in the middle of nowhere about a mile’s hike from road. Great find!
Other than that I enjoyed following the “Lewis and Clark Historic Trail” along one of the tributaries of the Snake River as we headed toward Washington, where the Snake will eventually feed into the Columbia. There’s the Columbia river again! It’s everywhere! This took us through the Nez Pierce Reservation, and to Lewiston ID, and Clarkston WA, right on the border between the states where that tributary we’d been following hit the Snake, separating the cities. I was really impressed by these towns- I regret not having more time to check them out because I could definitely see myself spending more time here.
