Castle Rock, Washington


Castle Rock is home to approximately 3,000 residents. One of the many unique items about this charming town is its spirit of volunteerism. Castle Rock community members are often gathering to assist with the annual America in Bloom competition, community clean-ups, or decorate for special events.


Castle Rock is a gateway to Mount St. Helens. Castle Rock is nestled between Interstate 5 and the Cowlitz River, located 134 miles south of Seattle and 63 miles north of Portland, Oregon. Castle Rock is the northern most city in Cowlitz County. Access to the Spirit Lake Memorial Highway (SR 504) connects the city to the Mount St. Helens National Monument and Spirit Lake recreation areas – two of the most outstanding tourist attractions in Washington State.


Castle Rock’s proximity to Interstate 5, intercontinental rail lines, deep water ports within 30 minutes and access to affordable power and water makes it poised for a variety of development. With a historic downtown, tourism, industrial and commercial availability the possibilities are endless.


The Castle Rock community is close-knit, welcoming and kind. Coming together with pride for where they call home, you can join in on community clean ups, large events such as the Festival of Lights, America in Bloom, or Mountain Mania. With three amazing schools that are well connected to the community, students are supported and involved. Castle Rock embodies the spirit of collaboration.
