Emerald Triangle

Emerald Triangle is an 18.8 km loop from Emerald Lake to Yoho Pass, across the Wapta Highline and Burgess Pass, then back to the lake. Plan on about eight hours and roughly 1,285 m of climbing as well as a similar descent. This is a hard alpine day for hikers comfortable with long climbs and rough mountain tread; it is far more than an extension of the easy lakeshore walk. Start early because the popular lot can fill early in summer and on weekends. Dogs may come on the route but must stay leashed.

The route leaves the Emerald Lake shoreline and climbs through forest before reaching the open pass country. Expect sustained uphill and switchbacks rather than a gradual stroll. The Yoho Pass trail reaches the pass, then the circuit retraces about 0.4 mile to the junction for Wapta Highline; that short repeat is part of the loop's route, not a separate hike. The tread grows rockier as the forest thins, so allow time for careful footing on the upper climb.

The long traverse below Wapta Mountain is the route's big payoff. Forest gives way to alpine meadow and shale slopes, with broad looks back over Emerald Lake and across the President Range. Wildflowers can brighten the open slopes in season. When you stop for a photo, leave a strip of the highline or its rocky meadow in the foreground; it helps show how far above the lake the route has climbed.

From the high traverse, the route crosses toward Burgess Pass and descends through steep forest switchbacks. This is the tiring part late in a long day, especially where the ground is wet or loose. Keep a steady pace and save time for the lower lakeshore return rather than treating the pass as the finish. The circuit comes back to Emerald Lake without a shuttle or a separate pickup.

Near the Yoho Pass approach, the trail crosses a broad alluvial fan cut by braided streams; short log bridges cross some channels. Higher on the circuit, the Burgess Shale fossil locality lies near the route. Its fossil sites are protected and are not open for independent exploring; access is controlled through guided hikes. Stay on the marked trail instead of following a tempting side path toward the quarry slopes.
