Forest Road 9 – Hyalite Canyon to Mount Ellis

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.
