Overview
Lake Plateau is a signature destination in the Absaroka-Beartooth Wilderness within Gallatin National Forest, a high alpine plateau dotted with dozens of lakes accessible via a strenuous 12-mile out-and-back. The route gains 2,400 feet from the forest road trailhead and delivers hikers into a landscape of remarkable beauty.
The plateau's lakes are excellent fishing destinations with valid Montana fishing licenses. The wildflower displays across the plateau in midsummer are exceptional, and the views from the rim look across multiple mountain ranges.
The Route
The trail climbs steeply from the trailhead through conifer forest before breaking above treeline and onto the plateau. The plateau section is relatively flat, allowing exploration of multiple lake basins from the main trail junction. Return the same way.
When to Visit
Mid-July through September. The plateau retains snow into early July most years. August offers peak wildflowers and the most reliable weather. September brings outstanding clarity and fall colors at lower elevations.
Practical Details
No permits required (as of 2026). Bear spray is essential. Proper food storage is required in grizzly habitat. Water from the lakes must be treated. Cell service is unavailable. The 10 Essentials are essential for this remote alpine route.
Getting There
From Livingston, Montana, drive south toward the Absaroka Mountains and follow forest road signs to the Lake Plateau Trailhead. High-clearance vehicle recommended. Contact the Gallatin Ranger District for current road conditions.
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.
