on Hwy 70
The small mountain community of Twain CA is just a few building along the river & highway; Densely forested w/ railroad tracks and private homes in the hills. RV park, post office & general store serve this locale. Feather River Hot Springs located nearby. Railroad runs the length of the canyon, so expect noises, as well as nature. This is a major trucking route, so you will hear some traffic if camping near here.
