Two of the Beartooth Mountains' most popular trails are connected by the more sparsely crossed Sundance Pass, providing sublime views of alpine lakes, early summer snowfields, and granite peaks.

The Lake Fork trailhead, about 12 miles from Red Lodge, starts at 7,200 ft. and meanders gently along Rock Creek through wide canyons toward Sundance Pass — climbing only 1,200 feet over five and a half miles. Lodgepole pine forests give way to alpine meadows bursting with colorful wildflowers and the occasional moose. Visits to Broadwater, Lost, and Keyser Brown Lakes provide opportunities to cool down along the way.

"Around six miles in, where most day hikers turn back, the trail turns much steeper — climbing 1,400 feet over the next mile and a half where September Morn Lake awaits."

Ample sites for solitude and camping line the lake just short of the tree line at 9,800 ft. A final push of 1,250 vertical feet over two miles takes one to the stunning vistas of Sundance Pass (11,047 ft), with views of Montana's fifth tallest mountain, Whitetail Peak (12,551 ft) to the west, the Hellroaring Plateau (10,000 ft) to the east, and the alpine lakes of the Lake Fork and West Fork basins below.

After relaxing in the cool breeze at the pass, the long descent along 54 switchbacks delivers you to the West Fork basin at 9,500 ft. and the refreshing waters of the West Fork of Rock Creek. Of course, deep snow well into mid-July often covers much of the trail, requiring a glissade down the north side of the pass and bypassing many of the switchbacks.

From the basin it's all downhill, through more lodgepole pine forest and the stunning Quinnebaugh Meadows. Plenty of campsites await on flat (and relatively rock-free) meadows under the shadow of the Silver Run Plateau and fading views of Whitetail Peak toward the pass. The West Fork of Rock Creek winds through bogs and quiet meadows where moose are often found, before cascading down the valley toward the quick descents of Sentinel and Calamity Falls. The last mile and a half opens up to burndown from the Cascade Fire of 2008, before reaching the West Fork trailhead at 7,600 ft.

For the ambitious, this 19.7-mile route can be completed in either direction in a single day, assuming an early start. Those wanting a more relaxing pace will find plenty of spots for camping along the way, as well as spur trails to Lake Mary (at Quinnebaugh Meadows on the West Fork trail) and Black Canyon Lake on the Lake Fork side — plus other options to explore.

Route
Breakdown

The Sundance Pass Loop can be run in either direction. Starting from the Lake Fork trailhead gives you a gentler warm-up before the steeper climb to the pass, with the long switchback descent on the West Fork side to finish. Arrange a shuttle between the two trailheads — or make it a true loop by hiking the connecting road.

A two-night approach is ideal: camp at September Morn Lake on night one, push over the pass on day two, and settle into Quinnebaugh Meadows before the final descent on day three.

"Standing at 11,047 feet with Whitetail Peak on your left and the full sweep of two river basins below — this is what we mean by finding your True North."
