The Mallard Lake Trail is the 3-mile hike to the lake’s south shore.
The trail gently climbs through a shallow ravine covered in colorful wildflowers and shaded by old trees. As you go up, the forest becomes more dense, but once you pass the ridge, the trail goes down towards the lake, surrounded by trees and tall grasses.
The trail is a popular ski trail during the winter. If you want to extend your hike, the Mallard Lake Trail is part of a loop that includes the Powerline Trail, Mallard Creek Trail, and Upper Geyser Basin Trail.
The trailhead is located just next to the Old Faithful, and its easy accessibility makes this hike very popular.
