Boulder River

Natural Bridge, on the Boulder River
Twenty-one miles south of Big Timber, MT (between Bozeman and Billings, on I-90), Highway 298 reaches deeply into the McCloud Basin, retracing the path the main stem of Boulder River toward its headwaters high in the Absaroka (Ab-SORK-ee) Range.
Just before the pavement ends, you'll come upon an wondrous example of water-on-rock erosion at Natural Bridge, through which the Boulder's thundering waters plummet 105 feet before resuming the journey to Jefferson River, a tributary of the mighty Missouri. The falls at Natural Bridge have captured the imagination of countless visitors, including at least one intrepid kayaker.
This site provides campers with a tolerance for "road shakes" what becomes a gravel (occasionally rutted) road for some 25 additional miles, deep into the Gallatin National forest, with farm inholdings on the western side of the river and the Absaroka Wilderness on the east. The mountains are one of the most privative landscapes Montana offers. But campers with a yen for beauty will delight in this plunge into the outback.
Wanderlust
Soon, one comes upon six riverside campgrounds, offering various degrees of seclusion and vistas. The sites are open year-round--first-come, first served--and accomodate 8-12 slots.Cutthroat trout become more abundant--and gullible--as one travels further up river. They also are smaller.
Upper Boulder River
Perhaps the best fly fishing is on the West Boulder--near the ranch of former NBC Nightly News anchor Tom Brokaw. The tributary forks off Highway 298 back to the north, near the historic town of McLeod.
