Serpent Trail is a mountain biking route in Idaho's Sawtooth National Forest, within the Ketchum Ranger District. The Forest Service manages the land, and the trail is an out-and-back of about 0.56 miles, with the high point at 6,820 feet and the low at 6,751 feet. That puts the climb at about 168 feet for the round trip, with the steepest stretch coming at 0.17 miles in, where the grade reaches 16 percent. Summer is the most comfortable time to ride. Typical averages from a nearby weather station in Ketchum show July highs around 80°F and lows near 45°F, and July and August run the fewest wet days of the year. That station sits about 930 feet lower than the trail, so expect it to run cooler up high. The Forbidden Fruit and Forbidden Fruit Trail #159 both lie about 0.3 miles away, and the Griffin Butte Connector is about a mile off. For fishing, the Big Wood River is roughly 3.6 miles away.
