Come play with us!

All Play Volunteer Days are when we host one-time volunteer activities that are open to anyone, whether you are a current volunteer with us or not. They include special family-friendly events to engage our youngest gardeners, unique Green Teen events designed for volunteers ages 15-19, full on All Play Days where we can take all comers and more.

All Play Days give you chance to help the environment, make new friends, try out volunteering for us and – hopefully – have a little fun! Plus, you get the benefit of free parking and free admission before or after volunteering, so you can enjoy our remarkable forests & gardens.

We typically host one All Play Volunteer Day each month at either our Cleveland Botanical Garden or Holden Arboretum campus. You can see the current schedule for 2026 here .
