Larch Valley essentials

Address: Moraine Lake, Banff National Park, Alberta, Canada

Larch Valley sits on the slopes above Moraine Lake in the Valley of the Ten Peaks and leads up toward Sentinel Pass; it is notable for extensive stands of subalpine larch that turn bright gold in autumn. The terrain is alpine and open above the tree line in places, with rocky trails, scree sections and wide, panoramic views of surrounding peaks.

The valley is best experienced on foot via a well-used trail that gains significant elevation en route to Sentinel Pass; many visitors do a day hike to enjoy the larches, alpine meadows and viewpoints. Wildlife is present in the area, so standard mountain precautions apply.

Visiting means dealing with mountain weather and limited parking at the Moraine Lake access point; summers are cool and the trail can still hold snow early in the season while autumn brings spectacular color but colder conditions. Expect crowds in the core hiking season, and check local conditions before setting out.

  • Golden larches: Dense stands of deciduous larch trees turn vivid gold in early autumn and are the valley’s main attraction.
  • Sentinel Pass viewpoint: The upper end of the valley opens to Sentinel Pass, offering sweeping views of surrounding peaks and glaciers.
  • Moraine Lake panorama: From parts of the trail you look down on turquoise Moraine Lake backed by the Ten Peaks for iconic mountain-and-lake views.
  • Alpine meadows and wildflowers: In summer the valley hosts alpine wildflowers and open meadows framed by rocky ridges.
  • Mountain wildlife: Keep an eye out for marmots, pikas and sometimes bighorn sheep along the trail and on nearby slopes.
