Ringed by soaring granite walls at the mouth of a classic glacial canyon, East Rosebud Lake is one of the most beautiful road-accessible spots in Montana's Absaroka-Beartooth country — and the gateway to what many consider the single finest backpacking trip in the Northern Rockies. A cluster of rustic cabins lines the north shore, forming a quiet, historic alpine hamlet at the very end of East Rosebud Road (Forest Road 2177), reached by driving 10 to 11 miles up a gravel road from the tiny town of Roscoe, southwest of Red Lodge.

The lake itself is a stunner — cold, clear water backed by cliffs, forest, and tumbling waterfalls, with East Rosebud Creek pouring in at its head. In 2018 that creek earned a rare federal Wild and Scenic designation, protecting it free-flowing for good. But for many visitors, it's the trailhead at the south end that draws them: the start of the East Rosebud Trail (#15), universally known as “The Beaten Path.”

This roughly 26-mile point-to-point traverse threads the very heart of the Absaroka-Beartooth Wilderness to the Clarks Fork Trailhead near Cooke City and Yellowstone's northeast corner. Climbing steadily some 4,000 feet to its high point near Fossil Lake on the Beartooth Plateau, it strings together an almost unbelievable procession of alpine lakes — Elk (about 3.5 miles in), Rimrock, Rainbow (8 miles), Lake at Falls, Big Park, Duggan, Twin Outlets, and Dewey — along with the magnificent Impasse Falls, where the creek plunges some 150 feet into little Duggan Lake. Most parties take three to five days, camping lakeside and fishing the cutthroat- and trout-filled waters along the way.

You don't have to thru-hike it to fall for the place, though. Day hikers commonly follow the lower trail to Elk Lake or the first waterfalls and turn around, soaking in wilderness scenery on an easy, family-friendly out-and-back. Anglers work the lake and creek, and the whole valley is a photographer's dream in the low light of morning and evening.

The lakeside East Rosebud Campground (Custer Gallatin National Forest) makes an ideal basecamp, typically open from late May into early September and often full on summer weekends. Note that much of the shoreline and the cabins are private property, so respect posted areas; direct lake access and boating are limited, and the real prize here is the scenery and the trail rather than a public beach.

This is high, wild, grizzly country. Carry bear spray and know how to use it, store all food properly, and be ready for sudden mountain weather — snow and freezing temperatures are possible even in midsummer at the higher lakes. Thru-hikers should arrange a car shuttle between the East Rosebud and Clarks Fork trailheads, which are a long, roundabout drive apart, and be prepared for stream crossings, lingering early-season snowfields on the high plateau, thick mosquitoes in July, and genuine remoteness far from help. The prime window is mid-July through September; earlier and you'll be wading snow up high, later and the first storms of autumn can shut the pass. However you experience it — a lakeside picnic or a five-day traverse — East Rosebud is Montana at its most magnificent.
