Bottleneck Lake and Snow Lake

Hidden in the remote and rugged beauty of northern Idaho’s Selkirk Mountains, Bottleneck Lake and Snow Lake offer a classic alpine hiking experience with crystal-clear water, granite peaks, and peaceful, uncrowded surroundings. These two glacial lakes are located within the Kaniksu National Forest, and hikers often visit both in a single out-and-back hike. The trail is especially popular in late summer and early fall, when wildflowers and golden larch trees fill the landscape.

Trail Overview

• Location: Selkirk Mountains, Kaniksu National Forest, near Bonners Ferry, Idaho

• Difficulty: Moderate

• Trailhead: Snow Lake Trailhead, Forest Road 658

• Estimated Time: 3–5 hours depending on pace and time spent at the lakes

What to Expect

The trail begins in a shaded, subalpine forest before gradually climbing through meadows and rocky terrain. You’ll reach Bottleneck Lake first, about 2.5 miles in, nestled in a granite basin with great spots to rest, swim, or fish. From there, continue another mile along the trail to Snow Lake, which sits in a dramatic bowl surrounded by towering peaks and often holds snow late into summer.

Expect clear water, scenic ridgelines, and relative solitude compared to more popular alpine lake hikes in Idaho. Both lakes are excellent for a lunch break, photos, or a quick plunge on a warm day.
