Overview
The Twin Lakes occupy a single cirque basin in the Anaconda-Pintler Wilderness, sitting side by side at approximately 8,600 feet below the Continental Divide peaks that define the Pintler Range's skyline. The seven-mile route to reach them is the most accessible significant hike in this section of the Beaverhead-Deerlodge National Forest, gaining 1,600 feet through classic subalpine terrain without the full commitment required by the Anaconda-Pintler Loop.
The lakes are distinct despite their proximity. The lower lake is slightly larger and more exposed, with a rocky shore and the divide peaks directly behind it. The upper lake sits in a more sheltered depression with better camping sites and tends to hold clearer water. Both support cutthroat trout populations that see relatively low fishing pressure given the distance required to reach them.
This trail works particularly well as an introduction to the Pintler Wilderness the terrain types it covers, from dense lower forest to open subalpine meadow to alpine cirque, represent the range's character in miniature. Hikers who complete this route will understand what the longer routes in the area offer and have a better sense of whether the full loop is within their range.
The Route
Miles 0 to 2: Trailhead to Subalpine Transition
The trail starts in lodgepole pine and transitions to spruce-fir forest within the first mile. The grade is steady and moderate not flat, but not brutal. A wilderness boundary register appears around mile 1. By mile 2, the forest is transitioning to subalpine character with more open patches and the first views of the ridgelines above. The lower wildflower slopes are at their best around miles 1.5-2.5 in mid-July.
Miles 2 to 3.5: Cirque Approach to First Lake
Above mile 2, the trail steepens toward the cirque headwall. The final mile-and-a-half involves more sustained climbing, though the terrain remains walkable without technical skill. The first Twin Lake appears at mile 3.5: a classic alpine lake with rocky shores and divide peaks behind it. The second lake is a 10-minute walk farther into the cirque.
When to Visit
July through September is the reliable window. Both lakes can be reached by late June in good snow years. September is excellent for uncrowded fishing and stable weather.

- 2-3 liters of water with filter or purification tablets
- Full rain gear for afternoon storms

Practical Details
No permit is required for day hiking as of 2026. Self-registration at the wilderness boundary trailhead register. Fires prohibited above treeline. Follow Leave No Trace principles. The national forest camping permit guide covers wilderness overnight procedures.
Getting There
From Anaconda, Montana, take forest roads south toward the Twin Lakes drainage. The Pintler Ranger District in Anaconda can provide current road directions. From Butte, take MT-1 west approximately 25 miles to Anaconda, then follow ranger district directions. Allow approximately 1 hour from Butte to the trailhead.
