Directions

The observatory is located at the top of the Blue Mountain Recreation area southwest of Missoula. To reach the Blue Mountain Recreation area, turn west on Blue Mountain Road off of highway 93 south of Missoula (by The PEAK Fitness Center). Head north by the entrance to the Blue Mountain Trailhead and follow the paved road around to the dirt road entrance (Forest Road 365). You’ll be turning west onto Blue Mountain Road 365 - drive up (past the frisbee golf course) for about ten and a half miles to an unsigned junction with an obvious road entering from the left. Take a sharp left (almost 180 degrees) onto this road (forest Road 2137), pass through an open gate - we will have a sign at this junction. Proceed another two miles to the fire lookout at the top of Blue Mountain. Park there and walk east about 0.3 mile on the narrow dirt road that follows the ridgeline. The Observatory Dome should be visible as you get part way down the road. Please note that the gate 2 miles below the lookout will be locked at the end of the evening, no car camping is allowed past this gate!
