Frat Boy Wall is a sport climbing area in the Bozeman Ranger District of Custer Gallatin National Forest in Montana, managed by the Forest Service. It sits right next to two other climbing areas, Bozeman Pass and Kitchen Sink, both about 0.1 mile away, which makes it easy to pair with them on a single visit. The area has six sport routes, all rated between 5.8 and 5.10b/c. Nagasaki is the easiest at 5.8, and Duck and Cover and Fatman are among the harder ones at 5.10a and 5.10b. The Natural, a 5.10b/c route, was first climbed with gear by Tom Jungst and later bolted by Simon Lohbeck. Summer is the most comfortable time to climb. Typical averages from a nearby weather station in Bozeman show July highs around 82°F with lows near 52°F, while winter brings highs in the low 30s and regular snow days from November through March.
