Rockport State Park is a 670-acre park in an ancient forest. The old growth was never logged, and the entire ecosystem remains in place, creating a rare, natural forest with a canopy so dense that minimal sunlight penetrates to the ground. The park stands at the foot of Sauk Mountain, which has an elevation of 5,400 feet and a steep but climbable trail to the top. Opened in 1961, the park derives its name from the community of Rockport. The town itself was named for the numerous large rocks near the boat landing on the Skagit River. The old-growth timber that is the park’s most immediately recognizable feature, covers nearly 600 acres.
