Southern Valley Trails

Southern Valley Trails is a cross-country skiing route in Idaho's Caribou-Targhee National Forest, within the Teton Basin Ranger District. The Forest Service manages the land, and the trail is about a mile from the district's boundaries. The route is an out-and-back of about 1.9 miles, with a one-way climb of about 150 feet from a low point of 6,667 feet to a high of 6,827 feet. The steepest stretch, a 10% grade, comes at about 0.9 miles. For skiing, winter is the season. Typical averages from the nearby Driggs weather station run from highs around 33°F and lows near 9°F in January to highs in the low 40s by March. That station sits several hundred feet lower than the trail, so temperatures on the route run cooler. The Nemo and Grumpy's Loop hikes start within a third of a mile. Mike Harris Campground is about a mile away, and Pine Creek Campground is roughly 6 miles off.
