This loop begins from the main trailhead area near the chateau. If you go first to Lake Agnes, you’ll confront a steep hill on a well-kept, wide path through the forest. You’ll pass a small lake, Mirror Lake, before continuing up to Lake Agnes and the teahouse, both dramatically framed beneath sheer rock walls. Stop here for your first refreshment. Next, a flat walk around the lake leads to very steep switchbacks on a rougher trail, soon reaching a saddle where you can choose to make a side trip to the panoramic summit of Big Beehive.

From there, a quick descent through thick forest leads to Highline Trail, which then makes a gradual descent to the Plain of Six Glaciers. Along the way, you’ll enjoy constant views over berry bushes that cover the slopes, toward snowy summits of surrounding peaks and glaciers clinging to their sides.

The Plain of Six Glaciers lies just ahead, as does another stop for tea. This teahouse is set back in the forest, but near a meadow overlooking the plain. The rock-strewn expanse collects meltwater and debris that cascades from the cirque of glaciers visible above. You can continue along the trail, past the teahouse, for more elevated views over the plain, looking back at Lake Louise. To return, take the Plain of Six Glaciers Trail, which loops back to the chateau at lower elevation, joining the ever-popular Lakeshore Trail along the way.
