OverviewBig Baldy is the highest point in both Judith Basin County and the Little Belt Mountain Range in North-Central Montana. The summit, elevation 9,175 feet, boasts views of the Highwood Mountains to the North and the Crazy Mountains to the South.
Getting ThereFrom US Highway 89, approximately 2.2 miles south of the turnoff for Showdown Ski Area, there is a poorly signed gravel road heading Southeast. This is Forest Service Rd 3328. This moderately well-maintained road, which can be managed in a passenger car in the summer, winds through the forest for approximately 17 miles. At 12 miles, you will come to Chamberlain Creek, which is signed. Just beyond Chamberlain Creek, not quite 12.1 miles on the odometer, is a clearing that makes a great place to park. GPS coordinates here are N 46.95847 W 110.63330 with an elevation of 7385 feet.
At this point, it’s a great idea to have the Neihart and Yogo Peak USGS Quads because bushwhacking is necessary for the first mile or so and this hike is right on the border of these two Quads. Starting out from the clearing in a northeasterly direction will eventually run you to the top of a ridge where a commonly used ATV track is present. From this ridge, the mountain is visible to the East and the route is unmistakable.
From the car by this route, you will gain approximately 1800 feet over about four miles to the summit. The entire hike is Class 1 walking.
