Volunteer days are held at Lake Wilderness Arboretum every Wednesday and Thursday, 9am to noon. Show up on the day that works for you. A volunteer waiver form will need to be completed. Youth under 18 will need their waiver form signed by a parent or guardian. The form can be filled out at your first visit or download the form, fill out at home and bring with you. Minimum age to volunteer (15+ w/out adult, younger ages welcome with an adult). Meet inside the nursery at the Arboretum office. The Arboretum will provide tools, please bring your own gloves.

Every October, residents of Maple Valley and the surrounding area come out to volunteer at various projects around the City. The Arboretum hosts several projects and loves to see all the helping hands. Sign up is organized by the Maple Valley Make A Difference Day committee.
