The trails that lead out from Emerald Lake are among the most popular in the park. The Emerald Lake Trail is a 5.2km (3.2-mile), all-abilities nature loop that leads from the parking area to the bridge at the back of the lake. At the end of the lake, it connects to the Emerald Basin Trail, an 8.6km (5.3-mile) round-trip hike ending dramatically in a natural amphitheater of hanging glaciers and avalanche paths. The Emerald Lake circuit alone will take 1 to 2 hours; the Emerald Basin Trail is a half-day hike taking from 3 to 4 hours.

The Yoho Glacier Moraine Trail is a half-day hike, 8.2km (5.1 miles) in length that passes by Laughing Falls en route to Twin Falls, the most popular destination in the valley. Energetic folks can continue to the top of Twin Falls, then over the Whaleback Trail for some of the most incredible views of glaciers in the park. Returning to Takakkaw Falls via the Whaleback and Laughing falls is a 20km (12-mile) circuit.
