This road-trace takes riders to and from the Upper Sunshine Reservoir toward the Shoshone National Forest. The way is pretty easy, except for a sketchy bridge at the start that adds a bit of peril in the way of vertical exposure.
Not recommended for kids or beginners, the bridge has a broad 24" I-beam through the middle. Don't stray from this beam or you'll plummet below. Once past the bridge, expect a doubletrack surrounded by tall grass. In all, this isn't an especially fun ride, just a means to climb toward the Shoshone National Forest.
