Lightning Dome is a climbing area in Idaho's Nez Perce-Clearwater National Forest, within the Salmon River Ranger District. The Forest Service manages the land, and the area sits among several other climbing spots and trails, making it a compact base for a day of rock and a walk. The most comfortable months for a visit are typically June and September. Typical averages from a nearby weather station run from highs around 74°F and lows near 48°F in June to highs around 77°F and lows near 45°F in September. That station sits about 18 miles away and roughly 175 feet lower than the dome, so temperatures at the dome run a little cooler. The area has one route, Stony Staircase, a trad climb rated 5.6. Lightning Dome - Left Side and Rolling Stone Wall are both about 0.1 mile away, and Cougar Creek Trail is about 0.4 mile off. For an overnight stay, Meadow Creek campground is about 3.7 miles away.
