The Highwood Mountains Trail in Lewis and Clark National Forest explores one of Montana's most geologically distinctive features: an isolated cluster of volcanic peaks rising from the central Montana plains northeast of Great Falls. The Highwoods are not technically part of the Rockies but share the same character as other isolated ranges scattered across the high plains.
The five-mile round trip gains 1,200 feet to a viewpoint with a wide panorama across the Missouri River breaks and the surrounding plains. The trail is accessible from Great Falls and makes an excellent half-day outing for visitors to central Montana.
The Route
The trail begins in the lower Highwood drainage and climbs through mixed shrub and conifer terrain that reflects the volcanic soils beneath. The upper slopes open into wildflower-covered meadows with good views developing by the two-mile mark. The turnaround point at 2.5 miles delivers the full panoramic view across the plains.
The descent follows the same route, with the broad Montana sky and plains horizon serving as a constant backdrop.
What to Expect
The Highwoods are drier than the main Rockies, and the vegetation reflects the plains climate: expect more grass and shrub cover with fewer dense forests. Wildflowers in June are excellent because of the open terrain and volcanic soils. The trail can be warm and exposed in midsummer; early morning starts are comfortable even in July.
The views from the upper trail are the defining feature of this hike. On clear days, the Missouri River breaks are visible to the east, and the main Rockies frame the western horizon.
Nearby
Great Falls is the practical hub, with all services available. The Lewis and Clark National Historic Trail passes through Great Falls, and the Lewis and Clark Interpretive Center there provides excellent context for the history of the region. The upper Missouri River above Fort Benton offers flatwater paddling through the White Cliffs section, one of the most scenic float trips in Montana.
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.
