Bridges of Bonner County
From the Moose Lake trailhead, take Moose Lake Trail #237 a half-mile to the signed junction for Blacktail Lake Trail.
Turn right and head south. The trail winds its way up the north and west slopes of Moose Mtn. The elevation gain is steady but not steep, and the trail is easy to follow. Some vegetation encroaches on the trail, but none has thorns. Views to the north are pretty. All stream crossings have bridges, but the trail can be muddy in places.
At about 2.70 miles, you will reach a signed junction. Staying south (right) will continue to Blacktail Lake. Turning left will lead up to Moose Mtn if you are interested in a bigger day. As you head south, the trail will gradually lose elevation, and there are a few more long bridges that keep you above the water that may gather underneath.
The lake has several areas to camp around it, and you are surrounded by mountains on three sides, making for a very scenic setting. Enjoy the views, then retrace your steps back uphill to the junction, then either directly back to the trailhead as an out and back, or onto the Moose Mtn Loop for the long way back to the trailhead.
