Johns Island sits on the South Carolina state line just south of the Charleston peninsula and is bordered to the north by the Stono and Wadmalaw Rivers. As the largest island in South Carolina, Johns Island encompasses an array of island living options and popular Lowcountry destinations. Upscale, modern apartment complexes and historic single-family homes can be found closer to the north of the island near Charleston.
The southern reaches of the island don’t lend themselves very well to large-scale residential development because of the surrounding marshland. However, the marshland is what makes Johns Island a hotspot for seafood and Lowcountry cuisine in general. Boating and fishing are wildly popular on the island, and many residents enjoy waterway access from their very own homes. The Angel Oak Tree is a popular tourist hotspot. The 60-foot-tall oak has a massive canopy that evokes the classic look of Lowcountry living. Downtown Charleston is just 12 miles away and makes for one of the most beautiful drives in the area.
