Welcome to Lake Union Park, where you’ll find something new on every visit.

The At Lake Union Park Working Group consists of many of the Partner Organizations that use Lake Union Park, or just Lake Union, as their hub.

Many of the participants are non-profit organizations who want to continue to provide access to and educate people about one of Seattle's gems, Lake Union.

To learn more about the Working Group and what they are up to, please visit our Working Group page. 

The Lady Washington and Hawaiian Chieftain, both home-ported in Grays Harbor and owned by the Aberdeen-based Grays Harbor Historical Seaport Authority, provide educational, vocational, recreational, and ambassadorial activities and experiences that promote and preserve the maritime history of Grays Harbor, the Pacific Northwest, and our nation while serving the needs of the community.

The Lady Washington is the Official Ship of the State of Washington. The Hawaiian Chieftain accompanies her on her voyages and goodwill missions. Both ships welcome the public during visits to ports in Washington, Oregon, California, British Columbia, and at Lake Union Park!

Imagine being a child fighting cancer, not leaving your hospital room except for tests and treatments, and then resting on the deck of a sailboat, smelling fresh air for the first time in a year. Imagine living with abuse every day at home, and then relaxing in safety on the sea. Imagine facing serious illness alone, and then finding friends who truly understand.

Now celebrating its 25th year, KidSail creates hope and community through sailing trips on the healing sea. Our guests are those living with cancer or other serious illness, families suffering from domestic violence, at-risk youth, and many others whose lives have been turned upside down.

The Museum of History and Industry (MOHAI) is the largest private heritage organization in Washington State.

Through exhibits, lectures, workshops, educational program and community events, MOHAI fosters an appreciation for the diverse history of the region.

Northwest Seaport is a nonprofit organization dedicated to the preservation and interpretation of the maritime heritage of Puget Sound and the Northwest Coast, and to the development of maritime-based educational programs and opportunities for the broad community.
