20 Cool Playgrounds

Play space at YMCA Camp H.R. Erdman (Waialua, HI)

In the last 14 years, KaBOOM!, a non-profit organization based in Washington, D.C., has helped to bring play spaces to more than 3 million kids across the U.S. and plans to deliver spaces to another one million children this year. The new playground at YMCA Camp H.R. Erdman in Waialua, Hawaii, is a 29,000-square-foot space designed by kids from the camp and surrounding area and constructed with the help of KaBOOM! and community volunteers.

The playground is a Nature Built playground, which means it's a natural playground that features the natural, native elements of the area. This play space uses reclaimed wood and recycled tires in its equipment, has a boulder garden (which makes a cool climbing structure), a slide that follows the contours of the hill it is built into, a maze created from native vegetation, an edible forest of native plants and it features an Imagination Playground in a Box. There is also an outdoor classroom, but the playground itself serves as a sustainable-building teaching tool for all who visit it.
