Boulder Mountain is a high mountain peak at an elevation of 4.035m (13,238ft) above the sea level, located in Chaffee County, Colorado, in USA. Full-sized vehicles might have problems. It’s one of the highest mountain roads of Colorado.
The road to the summit is gravel and rocky. It’s called Forest Service Road 279. It’s impassable in winters. Avoid driving in this area if unpaved mountain roads aren't your strong point. Stay away if you're scared of heights. 4x4 vehicles required. It is probably best for ATVs but 4x4 vehicles can manage it just fine. The trail is extremely narrow, and could be dangerous if not impossible if you were to meet someone coming the other direction.
