Environmental Club
The GVHS Environmental Club is one of the school's many non-athletic student clubs. It has the stated goal of "provid[ing] students with opportunities to spend time outdoors while helping better the Garnet Valley community." The club has several projects which its members contribute to, including a nature trail and a compost bin. In January 2019 and 2020, the club hosted a "holiday tree drive", through which locals could drop off Christmas trees which would later be turned into wood chips and used in the club's nature trail. This event was advertised via the Bethel Township Facebook account.

After the school's Hi-Q team won the national competition in 2016, their winnings were donated to the environmental club.
