Membership – Lewis and Clark National Historical Park.

Our Mission: To promote Fort Clatsop and enhance the public’s understanding of the Lewis and Clark Expedition and its significance.

Support Lewis and Clark National Historical Park with YOUR membership!

The Lewis & Clark National Park Association (LCNPA) was established in 1963 as a 501(c)3 non-profit organization for the purpose of supporting National Park Service educational and interpretive activities at Fort Clatsop.

Our contributions include purchasing land for the park, funding the construction of trails and exhibits, publishing books, and supporting educational activities. The Association receives no public funds, nor is it funded by any private endowment.

With your membership, we can improve the Lewis and Clark National Historical Park and conserve the legacy of the expedition, promote America’s unique natural and cultural heritage, and appreciate our natural world.
