Big Timber is the perfect basecamp for some epic snowmobile adventures. Some of the best riding under Montana’s open sky is found in the Crazy Mountains and the Boulder River Valley. Enjoy stunning scenery, deep untouched backcountry, rugged ridgelines, old mining country, and groomed trails all in one place. With a long snowmobile season and breathtaking landscapes Sweet Grass County is a sled heads playground.
The beautiful Boulder River Valley offers trails for a variety of skill levels. The groomed Boulder River Snowmobile Trail is located South of Big Timber and runs 16 miles along designated wilderness. The Boulder Canyon Trail runs 25 miles along the Boulder River cutting through the scenic Absaroka and Beartooth ranges to the old mining town of Independence. The Dry Fork Trail runs 7 miles to Dry Fork Pass offering plenty of powder play with a scenic view at the end.
