Overview
Upper Flint Creek Canyon offers a pleasant creek canyon hike through Deerlodge National Forest, combining accessible terrain with mountain views and good fishing in a historic mining district. The 5.8-mile out-and-back gains 1,000 feet and is rated moderate, making it suitable for hikers of most ability levels.
The canyon's clear creek, wildflower margins, and views to the Flint Creek Range above make this a rewarding destination for a half-day outing from the Philipsburg area. Fishing is a major draw, and Flint Creek is known for quality brown and rainbow trout.
The Granite Mountain Trail provides a much more demanding option in the same mountain range for those wanting a summit challenge.
The Route
The trail follows Flint Creek upstream from the highway trailhead through the narrowing canyon. The first mile is the widest and most accessible section, with the canyon walls becoming more dramatic in the middle section. The trail continues upstream to a natural turnaround point with views of the upper canyon and surrounding ridgelines.
When to Visit
May through October. The lower elevation makes this one of the earliest trails to open in Deerlodge National Forest. Spring wildflowers and high creek flows are excellent from mid-May through June. Fall offers pleasant temperatures and fall foliage.
Practical Details
No facilities at the trailhead. Water from Flint Creek must be treated. Dispersed camping is permitted on Deerlodge National Forest lands. A valid Montana fishing license is required to fish. Review Leave No Trace principles.
Getting There
From Philipsburg, Montana, drive west on Highway 348 approximately 6 miles into the upper Flint Creek drainage. The trailhead is on the south side of the road. A passenger vehicle can manage the drive.
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 moderate 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.
