Castle Rock:
Where Past, Present and Future Come Together

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.

(Link to map of Castle Rock.) It is the northern most city in Cowlitz County, with a population of 2,120. Spirit Lake Memorial Highway (State Route 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 historic downtown features a wide variety of shops, antique stores, restaurants, and accommodations.

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.
