Bridal Veil Falls, Natural waterfall in Mount Index area, Snohomish County, United States.

Bridal Veil Falls is a 1,328-foot waterfall that flows from Lake Serene directly to the South Fork Skykomish River on the creek of the same name. It is a perennial 150-foot-wide drop with four tiers, two of which (350 feet and 250 feet, respectively) are clearly visible. It lies in the Mount Baker-Snoqualmie National Forest.

The waterfall formed during the last ice age when glacial movements carved deep valleys and exposed the underlying rock formations beneath the surface. These geological processes created the landscape that visitors see today.

The name comes from the veil-like shape of the 150-foot-wide drop, which fans out over four tiers below Lake Serene. The falls lie in Mount Baker-Snowqualie National Forest, and the Lake Serene trail that passes them is a popular day hike from the U.S. 2 corridor near Index. Visitors today see the two clearest tiers, of about 350 and 250 feet, from a viewpoint on the trail.

The trail starts at a parking area off U.S. Route 2 and climbs to the falls. The round trip is about 4 miles with roughly 1,300 feet of elevation gain. The path is steep and rocky in places, so wear sturdy footwear and carry water.

During winter months, the water partially freezes and forms large ice formations that change shape throughout the cold season. These ice structures develop only under certain conditions and offer a completely different visual experience compared to the flowing summer cascade.
