Overview

Trident Peak rises above the southern reaches of Gallatin National Forest, a strenuous summit with panoramic views that extend into Yellowstone National Park to the south and across the Gallatin Range in all other directions. The 11.2-mile out-and-back gains 3,200 feet and is considered demanding both for its length and the Class 2 to 3 scrambling required in the upper section.

The summit's three rocky pinnacles give Trident Peak its name, and the view from the top ranks among the best in the forest. The proximity to Yellowstone adds a unique dimension: looking south from the summit reveals the vast Yellowstone Plateau, one of the world's most significant thermal landscapes.

The Route

The trail begins in conifer forest and climbs steadily throughout. The lower half is forested; the upper half opens to exposed rocky terrain with progressive views. The final approach to the summit involves Class 2 to 3 scrambling on solid rock.

When to Visit

Mid-July through September. Snow and ice on the upper summit can persist into early July. Afternoon thunderstorms are a major concern on this exposed summit; plan to be descending before noon if storms are forecast.

Practical Details

No facilities at the trailhead. Carry all water; no reliable sources on the upper route. Bear spray is recommended. The 10 Essentials are essential for this remote summit.

Getting There

From Bozeman or Livingston, follow US-191 south toward Yellowstone and then forest roads to the Trident Peak Trailhead. High-clearance vehicle required. Contact the Gallatin Ranger District for specific directions.

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.

Safety Considerations

The strenuous rating reflects the trail's general character under typical conditions. Weather, seasonal snow, and trail conditions can change the experience significantly. Carry the 10 Essentials on any full-day outing. Inform someone of your plans and expected return time before heading out, particularly on longer or more remote trails. Cell service varies throughout Gallatin National Forest and may be unreliable in canyon bottoms or remote terrain.
