School Overview

Greencastle-Antrim Senior High School sits in the heart of Franklin County's rolling farmland, about 10 miles south of Chambersburg and just a few miles from the Maryland border — a quietly underrated corner of Pennsylvania with a strong sense of community and small-town roots. The school punches above its weight in math, making it a solid fit for families who value STEM while still wanting that close-knit, everyone-knows-your-name high school experience. If you're drawn to lower cost of living, easy access to the outdoors, and a school where your kid isn't just a number in a crowd, Greencastle is worth a serious look.
