Lake Wilderness Arboretum
Every first and second Saturday throughout the year, 9 AM – noon

The first Saturday of every month is a convenient time for people with jobs or who are in school but still want to make a contribution. Lake Wilderness Arboretum garden manager, Susan Goodell, or property manager, Bob Wahlberg, will be on hand with a list of tasks tailored to your abilities.  Sometimes we spread chips or mulch.  Sometimes we pull weeds or remove brush.  There is always a lot to get done at the arboretum and your assistance is deeply appreciated.
Lake Wilderness Arboretum is located at 22520 SE 248th Street, Maple Valley.
