Willamette Mission is one of the most significant and beautiful historic sites in the Willamette Valley. The park occupies land where the first mission for American Indians was founded in 1834 by the Reverend Jason Lee. Members of the Methodist Mission were later active in the formation of Oregon government. A monument is located in the park providing information on this settlement. The original mission buildings are represented by framed outlines called ghost structures. A landing for the Wheatland Ferry the first to carry the covered wagon across the Willamette River in 1844 is in the park.
The park offers many daytime opportunities for boaters, anglers and other users. Some of Willamette Mission's 1,680 acres hold filbert and walnut orchards. The nation's largest black cottonwood is in the park (it's older than the U.S. it's been around for over 250 years). There are grassy meadows surrounded by an array of flowers, plants, and trees. For those that enjoy water, there's Mission Lake and the Willamette River.The excellent picnic facilities are reservable for large groups. There are picnic shelters, electricity, restrooms, water faucets etc.
