Celebrate Earth Day in 2023 at Festival Park with the POST Partners Volunteer Program and The Local Colorado. Start the day in Festival Park with a volunteer activity giving back to Mother Earth by planting native grasses in the plaza area and removal of invasive plants in Sellars Gulch. The festival, immediately following the volunteer activity, will include educational information from local nonprofits, demonstrations, vendors featuring upcycling goods and food trucks. It'll be a day to act, learn and enjoy! Registration is required for the morning volunteer activity.
