15.9 acres of wooded land in a high, non-flood zone with a 1.5-acre pond. Zoned AGR. Adjacent to 95 acres of recently protected farm land, Grayson Oaks. Located 15 miles to downtown Charleston. Contiguous 7.25 acres also available, listed separately.
Johns Island, located between the Ashley River and the Stono River, is a rural and coastal Charleston neighborhood with live oaks and tidal creeks. The Lowcountry landscape sets the pace, with marsh views, farm stands, and long two-lane roads leading to waterfront landings. The neighborhood’s character concentrates around the Maybank Highway corridor near River Road, where seafood counters, local markets, and casual patios cluster in a steady hum. Community pillars include The Royal American (on the island’s edge), Low Tide Brewing, and the Charleston Tea Garden. Architecture ranges from older cottages and ranch homes to newer elevated builds designed for floodplain living. Trails and boat ramps shape daily routines, with sunsets often framed by spartina grass and wide skies.
