Castle Rock, city in Cowlitz County, Washington, United States
Castle Rock is a small city in Cowlitz County, Washington, situated between the Cowlitz River and Interstate 5. The town spans both sides of the river and is surrounded by dense forests and green vegetation, giving it a quiet and natural appearance.
Castle Rock was founded in 1852 by Eliza and William Huntington, who claimed the first land next to a large rock they named Castle Rock. The town grew slowly through river commerce and shipping, becoming officially incorporated as a city in 1890 after the Northern Pacific Railway came through in 1872.
The town takes its name from a large rock formation that served as a landmark for local Native Americans and fur traders in the 1800s. This rock remains a symbol of the city and continues to shape how residents and visitors understand the place.
Castle Rock sits conveniently between Seattle and Portland and is easily reached via Interstate 5, making it a practical base for visits to Mount St. Helens. A local trail along the Cowlitz River offers walking and biking opportunities, while the Spirit Lake Memorial Highway connects the town to the national monument.
