The famous Lolo Trail, now paralleled by a modern road, follows the north bank of the Lochsa River for many miles. A few primitive roads and a lot of trails head north into wilderness and timber country, but the south bank and the mountains behind are less developed. To provide access the Forest Service has built a few bridges, designed for horses and mule trains, not cars, that lead into trail networks. Note the high railings and the single track down the middle.
