Lightning Basin is a moderate out-and-back hike in the Emmett Ranger District of Idaho's Boise National Forest, about 3.5 miles long with a one-way climb of 583 feet. The trail starts at a low point of about 6,242 feet and reaches a high of about 6,830 feet. Summer is the most comfortable time to go. Typical averages from a nearby weather station at Deadwood Lodge show July highs around 82°F with lows near 40°F, and September highs around 73°F. That station sits roughly 900 feet lower than the trail's high point, so temperatures on the basin run cooler. The trail is on natural surface and allows both horses and bikes. Onion Valley is about a mile away, and Lightning Ridge and Granite Basin are within 4 miles. Rattlesnake Campground is about 6 miles off.
