William O. Douglas Wilderness

William O. Douglas Wilderness is a protected natural area in central Washington covering about 169,000 acres of varied terrain. It features high ridges, subalpine meadows, and old-growth forests of fir, hemlock, and cedar trees.

This area was established in 1984 to honor Supreme Court Justice William O. Douglas, who grew up in nearby Yakima and owned a cabin in Goose Prairie. The designation reflected his deep commitment to protecting wild lands.

The land held deep meaning for Native American peoples who lived here for generations, with their presence visible through traditional sites scattered throughout the terrain. Walking through these areas, visitors can sense the long history of human connection to this landscape.

Visitors can explore more than 66 different trails spanning about 250 miles, with most routes suitable for horse packing and extended backpacking trips. The variety of trail difficulty means both beginners and experienced hikers can find suitable routes.

The region shows extreme differences in rainfall, with the western side receiving about 120 inches per year while the eastern side gets only about 20 inches. These stark contrasts create two completely different ecosystems within the same protected area.
