About St. Marys

St. Marys is a coastal Georgia city in Camden County, set on the St. Marys River near the Florida line. Spanish expeditions explored the river area in the 1500s, and the town later became one of Georgia's older coastal communities. Today St. Marys is known as the gateway to Cumberland Island National Seashore, with ferry access, a waterfront downtown, the St. Marys Submarine Museum, and local Mardi Gras events. It feels historic and maritime, with a residential coastal pace and wild barrier-island scenery nearby.
