Forest Road 9 – Hyalite Canyon to Mount Ellis
Gallatin Range high country connection
Forest Road 9 cuts deep into the Gallatin Range, connecting the popular Hyalite Canyon recreation area to the remote Mount Ellis backcountry through 18 miles of high-elevation forest and meadow terrain. The route starts near Hyalite Reservoir and climbs steadily through dense lodgepole pine and subalpine fir, passing the historic Blackmore Lake trailhead before cresting a 7,800-foot ridge with sweeping views across the Gallatin Valley. The middle section traverses a series of alpine meadows where snow lingers well into July, and several creek crossings can become problematic during spring runoff.
This is a moderate to difficult route requiring high-clearance 4WD and experience with rocky, rutted forest roads. The surface alternates between loose rock, exposed granite, and muddy sections that hold moisture throughout the summer. Best tackled June through September, though early season requires careful assessment of snow conditions at higher elevations. No permits needed, but dispersed camping is excellent throughout the national forest sections. Come prepared for rapidly changing mountain weather and carry recovery gear – cell service is nonexistent once you leave the Hyalite area.

Frequently asked questions
Can a stock Jeep Wrangler make it through this trail?
Yes, a stock Wrangler will handle this trail fine. High-clearance 4WD is required for rocky sections and water crossings, but no extreme modifications needed.
Is Forest Road 9 passable in late May or early June?
Trail typically opens in June once snow melts at higher elevations. Check with Gallatin National Forest before heading out in early season as snow can linger at 7800+ feet.
Do I need any permits to run this trail?
No permits required for the trail itself. Standard Gallatin National Forest rules apply for dispersed camping and fire restrictions.
What's the most challenging part of this route?
Rocky sections in the middle portion and water crossings can be tricky, especially during spring runoff. The elevation gain is gradual but sustained.
Are there good dispersed camping spots along the way?
Yes, several established dispersed sites exist along the route, particularly in meadow areas before reaching maximum elevation. No water or facilities available.
