Free and open to the public year-round, the Olympic Sculpture Park was built in 2007 right on the waterfront by the Seattle Art Museum. The park is industrial unlike others on the list. It exists within sprawling natural landscapes, which gives it a totally different vibe. There are green spaces throughout, and the backdrop of the Puget Sound is something that you can’t get in a forest or prairie.
