Overview
The Pintler Pass Trail enters the heart of the Anaconda-Pintler Wilderness through Deerlodge National Forest, crossing a high mountain pass with panoramic views and descending through a basin of alpine lakes and wildflower meadows. The 14-mile loop is considered strenuous and can be completed as a long day hike or a comfortable overnight backpack.
The Anaconda-Pintler Wilderness is one of Montana's most scenic and least-visited wilderness areas. The Pintler Range presents jagged peaks above broad alpine basins, and the loop route samples the best of this landscape.
For a longer circuit through the same wilderness, the Pintler Pass Loop extends the experience significantly.
The Route
From the Middle Fork Trailhead, the trail climbs steadily through conifer forest before entering the open alpine terrain of the upper basin. The pass crossing at the high point delivers views north into the Clark Fork drainage and south into the Big Hole Valley. The descent back to the trailhead passes through the best lake and meadow terrain of the route.
When to Visit
Mid-July through September. Snow can persist at the pass into early July. August offers peak wildflowers and the warmest temperatures. September brings solitude and fall colors.

Leave No Trace
This trail receives enough use that following Leave No Trace principles is important for preserving the experience for future visitors. Stay on the marked trail to prevent erosion. Pack out all waste. Avoid camping within 200 feet of water sources or the trail. Use existing fire rings only where campfires are permitted, and check current fire restrictions at checking conditions before you go before any visit. The trail and surrounding terrain remain in good condition because previous visitors have respected these norms.
Safety Considerations
The strenuous rating reflects the trail's general character under typical conditions. Weather, seasonal snow, and trail conditions can change the experience significantly. Carry the 10 Essentials on any full-day outing. Inform someone of your plans and expected return time before heading out, particularly on longer or more remote trails. Cell service varies throughout Deerlodge National Forest and may be unreliable in canyon bottoms or remote terrain.
