The rock garden’s pond, island and bench on the north side of the original Lilac Park on Highway 100 and Minnetonka Boulevard survived road construction.

Known as Monkey Island or Hidden Park, we prefer the name Rock Island Park. Now hidden behind a sound wall, there’s growing interest to restore these historical Lilac Way structures. Learn more.
