Overview
Crow Creek flows west from the Big Belt Mountains toward the Missouri River and Canyon Ferry Reservoir, draining a forested valley that sees a fraction of the traffic of Helena-area trails. The 8-mile out-and-back along its drainage is a moderate route through the Helena-Lewis and Clark National Forest that rewards hikers who make the additional drive from Helena with genuine solitude and consistent forest character.
The Big Belt Mountains east of the Continental Divide have a drier character than the ranges to the west more ponderosa pine and Douglas fir at lower elevations, with spruce-fir taking over above 6,500 feet. The Crow Creek drainage is typical of this landscape: a clear mountain stream with a defined forest corridor of mature trees, the kind of place where the absence of a crowd is itself one of the main attractions.
The trail's 1,200-foot gain and 8-mile length put it in the middle of the moderate range more demanding than the Helena-area creek walks, less so than the Boulder Lake approach. It works well as a second-day option for hikers who want a quieter complement to the trails closer to the city.
The Route
Miles 0 to 3: Trailhead to Mid-Drainage
The trail begins in open terrain near the trailhead before entering the creek corridor proper. The first three miles follow the creek through mixed forest with a steady, manageable grade. Water is accessible from the creek throughout this section. The forest becomes denser above mile 2, with mature Douglas fir dominating the lower slopes and spruce-fir increasing as the trail gains elevation.
Miles 3 to 4: Upper Drainage
Above mile 3, the trail steepens slightly and the drainage narrows. The upper sections are quieter and less traveled, with a more remote character than the lower approach. The turnaround at mile 4 is at a natural flat section where the creek makes a bend a good spot for lunch or a break before retracing.
When to Visit
June through October is accessible. The lower trailhead elevation makes this trail available earlier in spring than the Big Belt high-country routes. Summer conditions are pleasant in the shaded forest corridor. Fall brings cooler temperatures and color in the aspen groves at the lower elevations.
Check current conditions before visiting using the conditions-checking guide.
What to Bring
Many hikers carry the following for Crow Creek Trail:
- 2 liters of water; filter for refilling from the creek
- Bear spray
- Fishing gear and Montana license
- Insect repellent in spring and early summer
- Rain gear for afternoon weather
Individual needs vary. The moderate terrain makes this accessible for regular hikers.
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 creek. For more on national forest camping procedures, see the camping permit guide.
Getting There
From Townsend, Montana (on US-12, approximately 35 miles east of Helena), take secondary roads south or southeast toward the Crow Creek drainage. The Helena Ranger District in Helena or the White Sulphur Springs Ranger District can provide current road numbers. From Helena, drive US-12 east to Townsend, then turn onto forest roads; allow approximately 1 hour total.
