Arlington’s EcoFest is a time of learning, volunteering, and celebrating from April 22 – May 23.
Most town-wide events are free, and most are open to the public. Some schools have special events just for their school community.
What used to be a single day celebrated on Earth Day, April 22, has evolved into nearly a month of environmental education and celebration.
