Lost Lake is a short, easy hike in the Absaroka-Beartooth Wilderness, within the Beartooth Ranger District of Custer Gallatin National Forest in Montana. The trail is about half a mile long, with a low point of 8,370 feet and a high of 8,504 feet, and it is an out-and-back route. The Forest Service manages the land, and the trail is natural-surfaced. Horses are allowed, but bikes are not. Summer is the most comfortable time to go. Typical averages from a nearby weather station at Silver Gate run to highs around 74°F in July, with July and August lows near 40°F. That station sits roughly 1,000 feet below the trail, so temperatures on the route run cooler. The hike is open from May 1 to September 30. Keyser Brown Lake is about a mile away, and the Keyser Brown Trail is about 1.6 miles off. M-K Campground and Limber Pine are both about 4.7 miles away.
