Forks of the Sky State Park

Forks of the Sky State Park is a 1,300-acre (530 ha) element of the Washington State Park System on the Skykomish River and adjacent to U.S. Highway 2, near Index, Washington. Although a separate park, it is administered by Wallace Falls State Park farther west on Highway 2.

The Index Town Wall, a popular 1,200-foot (370 m) rock climbing and BASE jumping wall with 500 climbing routes documented by 2003, was acquired by the state in 2010, and is part of the park. The base of the wall has a blocked tunnel created by the test of a tunnel boring machine that was sent to dig under the English Channel. The Wild Sky Wilderness can be reached through the state park.

Forks of the Sky State Park occupies a particular place in the imagination of American public lands. As a State Park in Washington, it represents a deliberate choice — by the people who advocated for its protection, and by the National Park Service rangers who maintain it — to keep this landscape available to anyone willing to make the trip. That accessibility is the quiet miracle of the park system.

The pages linked below break the visit down into the four practical questions every traveler asks: where can I hike, where can I sleep, what else is worth seeing while I'm in the area, and what should I know before I show up. Each one is written from the perspective of someone planning their first trip — assume nothing, explain what's worth explaining, and skip the marketing language. If you've been here before, treat these guides as a refresher and a way to discover the corners you missed last time.
