Lake Haiyaha in Rocky Mountain National Park has transformed from a tranquil, clear retreat to a dazzling spectacle after a major June 2024 landslide in Chaos Canyon.
This event washed fine rock particles—known as rock flour—into the lake, creating a stunning milky, bright green color that now draws crowds of curious visitors.
The landslide's origin on the southern slope of Hallett Peak has been confirmed by park officials, but preliminary studies report the ecosystem remains stable, with no serious impact on local fish or plants.
Reaching Lake Haiyaha requires a moderate 4-mile round-trip hike from the Bear Lake Trailhead, passing scenic highlights like Nymph Lake and Dream Lake.
With the surge in popularity, early arrival and preparation for rocky terrain are smart moves.
The lake’s luminous waters continue to awe hikers and photographers visiting Estes Park and beyond.
