From Kaslo, BC head North out of town on Hwy 31. Stay on the highway until you hit the gravel near the south end of Duncan Lake.
Riding along the West side of the North end of Kootenay Lake which can be seen occasionally through the trees. Just beautiful country to see if you are not too busy concentrating on the road.
Pavement is generally good quality with little to no shoulders. Nice curves particularly coming out of Kalso.
There is a dam at the south end of Duncan lake if you are interested in seeing dams. While in Kaslo you have to check out the SS Moyie stern wheeler. The original of the replica located at Heritage Park in Calgary.
