Of the original Lilac Park near Minnetonka Boulevard, only the pond, island and bench on the north end survived road construction. The beehive fireplace and table on the park’s south end were moved before it became an entrance ramp.

Known as Monkey Island or Hidden Park, we prefer the name Rock Island. Now hidden behind a sound wall, we’re raising awareness for these historical Lilac Way structures. Learn more.

Rock Island, June 2019

A dedicated group of volunteers have weeded, excavated and transformed this hidden 1939 Lilac Way park into a gem. Their dedication proves that this historic Lilac Way park deserves to be preserved as a companion park to the restored Lilac Park near Nordic Ware.
