Arlington Echo Outdoor Education Center is the headquarters of the Environmental Literacy and Outdoor Education Office. AACPS purchased Arlington Echo in 1971 from the Arlington Presbyterian Church of Baltimore. The 24-acre youth camp was named Arlington Echo because a call from the bluff would echo back from across the Severn River. AACPS had previously rented the property to be used as the “Arlington Echo Outdoor School.” In 1974, the site became known as the “Arlington Echo Outdoor Education Center.” Arlington Echo now serves as the outdoor education site for the fourth grade environmental literacy program and the “home base” for the many other programs overseen by ELOE Office.
