The best walks and hikes in the Pioneer Mountains

This guide focuses on the Pioneer Mountains located in southwestern Montana, within the Beaverhead-Deerlodge National Forest. This range is distinct from the Pioneer Mountains in Idaho.

The prime hiking season is typically from July through September, when the high-elevation trails are mostly free of snow. The Pioneer Mountains Scenic Byway, which provides access to many trailheads, is also fully open during this period. Be prepared for afternoon thunderstorms, a common occurrence in the summer.

Yes, for a shorter, family-friendly outing, consider the Bannack loop. This easy walk explores the historic Bannack State Park, offering a glimpse into Montana's mining past. Another unique family activity is visiting Crystal Park, where you can dig for your own quartz crystals.

The Pioneer Mountains are renowned for their beautiful alpine lakes. For a rewarding moderate hike, the Tendoy Lake Trail is an excellent choice. If you're looking for a shorter trek, the Deerhead Lake Trail leads to another scenic lake through forested terrain.

For a strenuous, full-day adventure, the Birch Creek Trail offers a significant challenge with substantial distance and elevation gain. This route rewards determined hikers with a true wilderness experience and impressive scenery.

Yes, the rugged East Pioneers are particularly well-suited for backpacking. Many hikers create multi-day loops to explore the numerous glacial lakes, such as the popular trek connecting Minneopa, Boatman, and Estler Lakes. The Rock Creek Trail can also serve as a starting point for longer excursions into the backcountry.

Most trailheads are accessed via the 49-mile Pioneer Mountains Scenic Byway, which runs between Wise River and the Grasshopper Valley. This road provides the main corridor through the range. Be aware that some spur roads to trailheads may be unpaved and rough, so a high-clearance vehicle is often recommended.

Yes, dogs are generally permitted on trails within the Beaverhead-Deerlodge National Forest, but they must be under your control at all times. It's important to be mindful of wildlife, such as bears, moose, and mountain goats, and to pack out all waste to keep the wilderness pristine.

The Pioneer Mountains host a diverse range of wildlife. It's common to spot elk, deer, and moose in the forested valleys. In the higher, rockier elevations of the East Pioneers, keep an eye out for mountain goats and bighorn sheep. Bears are also present in the area, so it's wise to carry bear spray and know how to use it.

The area is rich with mining history. You can explore remnants of this past on hikes like the Hendricks/Apex Mill Site loop. The nearby ghost town of Coolidge and the abandoned Elkhorn silver mine also offer fascinating glimpses into the region's boom-and-bust era.

Weather in the mountains can change rapidly, so it's essential to pack layers, including a waterproof jacket. Sturdy hiking boots are recommended as many trails are rocky. Also, bring plenty of water, snacks, sun protection (hat, sunscreen), a map, and bear spray. Cell service is unreliable, so a satellite communication device is a good idea for safety.

The routes in the Pioneer Mountains are well-regarded by the komoot community. Reviewers often praise the solitude and pristine nature of the trails, along with the stunning alpine lake scenery. The area is particularly valued by those looking to escape the crowds of more popular Montana destinations.
