Castle Rock is nestled in the valley of Mt St Helens, and is a gateway to the northern entrance to the volcano on State Route 504.

Known for its scenic beauty and outdoor recreation, Castle Rock sits along the Cowlitz River and offers easy access to hiking,
fishing and nature trails. Since 2011 the town has become renowned for its award-winning volunteer-led flower program,
which fills the streets with vibrant hanging baskets, storefront containers and garden displays throughout the city.
This community effort not only embraces the towns natural beauty but also reflects the pride and spirit of its residents.

Castle Rock Washington

The town’s namesake, a 190-foot-high rock, was a landmark for Cowlitz Indians and Hudson’s Bay Company traders as early as 1832. Castle Rock prospered as a Cowlitz River steamboat port and trading center for valley farms. A local sawmill was the first to produce cedar shingles, using the Western red cedar, which grows in abundance in the region.

Castle Rock is a wonderful place to live, work and play. It’s a community where the people are as resilient and vibrant as the natural features that surround their home; a place where life-long residents and visitors alike feel they are part of the same tight-knit family.

Over the years, community organizations and volunteers have joined forces with local government to create an impressive menu of year-round recreational activities, town festivals and cultural attractions. They have helped make Castle Rock a place where people not only want to come … but a place people want to stay.

Citizens and government work in partnership with business and industry to support and enhance the city’s diverse economic base. The fruit of their efforts can be seen in a thriving downtown core, bustling I-5 business district and an ever expanding mix of employment opportunities. People in Castle Rock understand that a balanced, prosperous economy fuels a healthy social environment.
