Hike through wildflower-filled meadows—watch for the light purple splash of wild iris in August—to a jade-colored alpine lake on this 18.9-mile out-and-back in the shadow of the rugged Beaverhead Mountains. This is primitive country: Keep your eyes peeled for mountain goats, bighorn sheep, and grizzlies.
