Description: This park used to be private property, but it was donated to the City of Sammamish to be a park and natural area. It was named for a giant glacial erratic that sits in the forest, just begging to be climbed on. Recently, the city added some natural play features in the upper area of the park, including tunnels for crawling through, a slide, a giant nest to play in, and a zip line. A stream runs through the meadow, providing hiding places for frogs. Kids will enjoy the gentle trails, and will find birds and fungi while exploring. There is still a private home that is in the park, and it is off-limits to the public.
