Two Mouth Lakes Trail

The Two Mouth Lakes Trail is located in the Kaniksu National Forest near Bonners Ferry in Northern Idaho. The trail starts by following an old logging road. Parking is typically available at the trailhead.

This trail is generally rated as moderate. While the initial 1.5 miles are on a forest service road, the subsequent climb involves a significant elevation gain of around 1,770 to 2,000 feet. Hikers describe it as a 'nice steady grind' that will challenge you physically and mentally, though it's not overly steep. Be aware of rough and uneven sections and boggy areas where boardwalks are provided.

The round trip distance to Upper Two Mouth Lake is approximately 9 to 9.1 miles. While many complete it as a day hike, the significant distance and elevation gain mean it can take a full day. It's also a popular destination for backpacking, allowing for a more relaxed experience.

The trail offers diverse scenery, from shaded fir and spruce canopies to marshy sections with boardwalks. Key highlights include the pristine alpine lakes themselves, with the lower lake featuring unique bays and the upper lake being larger and deeper. You'll also find spectacular panoramic views of the granite-faced Selkirk Crest and glacier-carved peaks, especially from higher elevations. A unique feature is the expansive granite field near Harrison Peak, scattered with large boulders and sub-alpine firs.

The Selkirk Mountains are known for their remote nature, and endangered species like grizzly bears and caribou roam here, though sightings are rare. You might also spot various wildflowers and huckleberries, particularly in late summer and early fall.

Yes, the trail is generally dog-friendly. However, as it's located within the Kaniksu National Forest, it's always best to keep your dog on a leash and practice Leave No Trace principles to protect wildlife and the natural environment.

Late summer and early fall are often considered the best times to visit. During these months, you can enjoy wildflowers and huckleberries, and the weather is typically more stable. Always check current trail conditions before heading out, as snow can linger at higher elevations earlier in the season.

Generally, there are no specific permits or entrance fees required for day hiking the Two Mouth Lakes Trail within the Kaniksu National Forest. However, if you plan to camp overnight, you should check with the U.S. Forest Service for any specific regulations or permits needed for backpacking in the area.

Yes, while the primary route is the Two Mouth Lakes Trail, sections of the hike also follow Cooks Pass Road for about 22% of its length.

The Two Mouth Lakes Trail is primarily an out-and-back trail, leading to the lower and upper Two Mouth Lakes and returning the same way.

Given the moderate difficulty, significant elevation gain, and potential for uneven terrain, it's recommended to bring sturdy hiking boots, plenty of water, snacks, layers of clothing, and navigation tools. Bear spray is also advisable due to the presence of grizzly bears in the region. If backpacking, ensure you have appropriate camping gear.
