Interlochen State Park is a public recreation area covering 187 acres (76 ha) between Green Lake and Duck Lake in Grand Traverse County, Michigan. It was the State of Michigan's first officially recognized state park. It was established by the Michigan Legislature in 1917; $60,000 was paid for the land. Originally named Pine Park, the park was created to preserve for future generations the virgin pine (Pinus strobus) stand. It is one of the few easily reached places in Michigan where old-growth (pre-European settlement) red pine can be found.
