The Possum Walk Trail is a flat path consisting of dirt, grass, and crushed-gravel terrain. The path travels from the Stennis Space Center parking area towards the Pearl River (waterway separating Mississippi and Louisiana). The trail is easy enough to follow despite not seeing a ton of trail maintenance. This trail starts to head into pretty secluded lands, and there are a handful of animals you should keep an eye out for (wild boar, black bears, snakes, etc.).
