Type: Backcountry or Sidecountry
Open year round, but the road up can get gnarly. There's lots of private land around so beware.
From Bozeman, head east on 90, until you get into Bozeman Pass. Take the first exit for trail creek, and take a right at the bottom of the ramp. Take Trail Creek road up about 3 miles, you'll see a large dark colored house and you'll think 'that's a bit overkill...', then turn right onto Goose Creek road. Follow the signs until you get to the trailhead (there's one more right with a trailhead sign).
From here there are lots of fire roads leading up to Chestnut Mountain, with lots of options for you decent. Keep in mind there is lots of private land around here, so stick to the upper part of the ridge to be sure. It had terrible snow when I skied it, so I went back onto the fire road as soon as possible, that's why I won't be putting a ski line on here.
The slopes are south facing and range from 20-35 degrees and have trees below, so be careful on some of them.
