Overview
Moose Lake is exactly what its name suggests: a high-country lake in a basin where moose are genuinely common, living in the willow thickets and marshy inlet that characterize the lake's northern shore. The trail via Flint Creek is a moderate route that works well for hikers seeking a satisfying day objective without the sustained demands of the longer Pintler routes.
The Beaverhead-Deerlodge National Forest encompasses this section of the Flint Creek Range, a quieter and less-visited subrange between Philipsburg and Anaconda. The terrain here is more forested and less dramatic than the divide country to the south, but the old-growth Engelmann spruce in the Flint Creek drainage is genuinely impressive mature trees with the girth and solemnity that comes from centuries of undisturbed growth.
The 6-mile round-trip and 1,400-foot gain place this squarely in the moderate category. The trail is well-defined throughout, with no route-finding challenges, and the destination is rewarding enough that the effort feels well-spent. Plan for an early morning start for the best moose-watching conditions.
The Route
Miles 0 to 2: Trailhead to Old-Growth Zone
The trail starts in second-growth pine before entering the Flint Creek drainage's old-growth section around mile 1. The change in forest character is noticeable: larger trees, more open understory, and a quieter atmosphere. The trail follows Flint Creek upstream with moderate but consistent elevation gain. Two stream crossings in this section require either careful rock-hopping or waterproof footwear in early season.
Miles 2 to 3: Final Approach to Moose Lake
Above mile 2, the trail steepens slightly as it approaches the lake basin. By mile 2.5, the willow thickets that signal Moose Lake's marshy inlet become visible. The lake itself sits at approximately 7,600 feet, shallow enough on the north end to support the aquatic vegetation that moose favor. The south end is deeper and clearer, with a rocky shore suitable for lunch.
When to Visit
The Flint Creek Trail typically opens earlier than higher-elevation Pintler routes late June is often feasible in average years. July through October is the reliable window. Fall aspen colors in late September and October are a bonus in the lower drainage. Morning starts are recommended for the best moose-watching; the animals are most active in the hour after dawn and before dusk.

What to Bring
Many hikers carry the following for this trail:
- 2 liters of water with filter or purification tablets
- Binoculars for wildlife watching
- Bear spray (both black and grizzly bears are present in the drainage)
- Waterproof footwear or dry shoes to change into after creek crossings in early season
- Insect repellent (marshy areas near the lake produce mosquitoes through July)
- Rain gear for afternoon weather
Individual needs vary.
Practical Details
No permit is required for day hiking as of 2026. No fee at the trailhead. Dispersed camping is permitted; follow Leave No Trace principles near the lake and stream. Moose encounters require extra caution never place yourself between a cow moose and her calf, and give all moose ample space. For more on responsible wildlife viewing, consult the USFS Deer Lodge Ranger District guidance.
Getting There
From Philipsburg, Montana (on MT-1 between Missoula and Anaconda), take forest roads east toward the Flint Creek drainage. The Deer Lodge Ranger District in Philipsburg can provide current road numbers and directions. From Anaconda, Philipsburg is approximately 25 miles west on MT-1. From Butte, allow approximately 1 hour via I-90 and MT-1.
