About Castle RockThe town's namesake, a 150-foot-high rock, was a landmark for Cowlitz Indians and Hudson's Bay Co. 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 from the western red cedar that grows in abundance in the region.
Castle Rock marks the beginning of the Spirit Lake Memorial Highway (SR 504), a scenic route that leads past the areas affected by the eruption of Mount St. Helens in 1980. The Mount St. Helens Visitor Center at Silver Lake is 5 miles east of I-5 exit 49.
