Green Mountain Trail - Big Timber

Green Mountain Trail (94) begins at the Natural Bridge and accesses Green Mountain and the East Boulder Campground.

The trailhead starts at the parking lot where it splits almost right at the beginning. The trail to the left stays on the north side of the river, the trail to the right crosses the Boulder River via a sturdy built wooden footbridge. The view from the bridge allows you to see the river disappearing underground into this cavernous hole. Some 200 feet away and below the river shoots out a rock face 30 feet into a large clear pool. There is also handicapped accessibility to certain viewing points of the falls.

Length: 5.5 miles. Moderate difficulty, medium use.
