There are multiple units of this park. One is discussed by Langille and Boardman in the 1946 parks department, along the river alignment around MP 50, between Cascade Locks and Wyeth.
Lang State Park consists of five separate areas along Interstate Highway 80N, approximately 13.4, 13.8, 16.7, 17.7 and 18.1 miles west of Hood River in Hood River County.
These five tracts vary in size from as little as 1.14 acres to as much as 67.78 acres, with a total of 161.67 acres in the park. All of the land was excess right of way obtained before building the road.
Most of the land is not suitable for park development. Retaining it in public ownership does preserve the lush growth of green trees and shrubs in the Columbia River Canyon which has long been the expressed desire of the Columbia River Gorge Commission.
The terrain is generally steep, sloping upward south of the highway. The timber cover is fir, maple, alder and other indigenous trees and plants.
No active use is made of the area.
