The waterfall is technically a result of the East Fork Lewis River forcing its way through a narrow, volcanic basalt constriction.
The park acts as a significant observation point for salmon migration during late summer and early autumn.
The site was designated a regional park to protect the sensitive riparian habitat and geological features of the river canyon.
The volcanic rock visible at the site is part of the extensive basalt flows that define much of the regional topography.
Lucia Falls Regional Park is a 24-acre park located along the East Fork Lewis River in Yacolt, Washington. The site is most recognized for its namesake waterfall, which cascades over a volcanic rock shelf. It serves as a vital spawning ground for fall Chinook salmon and summer steelhead. The park features a primitive trail system that meanders through native forest and along the riverbank. Visitors can access a small gravel bar and rocky beach area near the river. The area is part of the Clark County regional park system and requires a parking permit for access.
The viewing platform overlooking the falls provides the safest and most comprehensive angle of the river drop.
