Overview
Storm Lake is one of the most remote lake destinations in Deerlodge National Forest, nestled in the Flint Creek Range at the end of a strenuous 9.6-mile trail. The route gains 2,400 feet from the forest road trailhead and delivers hikers to a pristine alpine lake with views of Granite Mountain and the surrounding Flint Creek terrain.
The remoteness is the defining characteristic of this destination. Storm Lake sees minimal visitor traffic compared to the better-known Montana lake destinations, and the fishing is exceptional for those with valid Montana fishing licenses.
The Granite Mountain Trail in the same area provides an even more demanding summit option for those wanting to push further into this remote terrain.
The Route
The trail climbs from the forest road trailhead through dense conifer forest. The first half is steep and forested; the upper half opens progressively as the trail approaches the lake basin. The lake sits in a glacially carved bowl with rocky slopes on three sides and views to the open ridgelines above.
When to Visit
Mid-July through September. Snow typically clears from the basin by mid-July. August offers the best wildflower displays and most reliable weather. September brings solitude and excellent clarity.
Practical Details
No facilities at the trailhead. Water from the lake must be treated. Dispersed camping is permitted. Bear awareness is appropriate in this remote terrain. The 10 Essentials are essential.
Getting There
From Philipsburg, Montana, drive west on forest roads to the Storm Lake Trailhead. High-clearance vehicle required. Contact the Deerlodge Ranger District for current road conditions.
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.
