Trail guide
Boom Lake Trail is a 10.2 km (6.3 mi) out-and-back from Boom Lake Day-use Area to the lake’s east shore. Allow about 3 to 4 hours for the full return. The path climbs gradually through mostly shaded forest, then drops over rougher ground to an alpine lake beneath steep cliffs. Go for the lake at the end: much of the middle stretch has few views.
From the day-use area, the route crosses Boom Creek on a wooden footbridge and climbs through forest. The long middle is straightforward but view-limited; mud is possible early in the season or after heavy rain. The surrounding forest includes large subalpine trees.
A boardwalk marks the approach to the lake, then the trail descends to the eastern shore. A past rockslide left boulders around the water, so the final stretch and shore are rough and uneven. Stay on Boom Lake Trail at the signed Taylor and O’Brien Lakes junction; that branch is a separate hike. At the shore, include a few foreground boulders with the lake and cliffs for a sense of scale, and watch your footing as you choose a place to sit.
The published 5.1 km distance is one way; the return follows the same path. Bring food and drinking water for the walk: none was confirmed on the route, and only picnic spots were noted at the trailhead. Dogs are allowed on Banff trails in summer unless a restriction is posted; keep them leashed and under physical control. Check current trail conditions and restrictions before setting out.
