Sisters State Park

Sisters State Park is an undeveloped forest area of about 28 acres along Whychus Creek, with old-growth Ponderosa pines and diverse wildlife. The land is split into three separate sections by two highways, but all connect to the nearby town center.

An entrepreneur named Louis W. Hill bought about 41 acres in 1939 and gave the land to Oregon to protect the old forest. This donation established what is now the state park.

The park shares its name with the nearby town of Sisters, which took its name from the Three Sisters volcanic peaks visible in the Cascade Range. This connection to the mountain landscape shapes how locals think about their place.

The park is easy to reach from downtown, even though its land is divided into separate sections. Visitors should be prepared to walk between the different areas to explore the entire site.

Whychus Creek runs through the land and its water levels change with the seasons, affecting local fish populations. These water movements create a living ecosystem that constantly shifts.
