The Trailer Boulders are a climbing area on Bureau of Land Management land in the Butte Field Office in Montana, about 11 miles from the town of Butte. The land is managed by the BLM, and the boulders sit close to other climbing and riding spots in the area. Summer is the most comfortable time to visit. Typical averages from a nearby weather station in Butte show July highs around 81°F with lows near 46°F, while winter highs stay around freezing. Snooter Boulder is just 0.1 mile away, and the BLM 11 and BLM 12 mountain biking routes are each about 0.3 mile off. Lower Pipestone Forest, another climbing area, is roughly 1.3 miles away.
