At the quiet end of Old A1A, where the road stops and the Atlantic begins, Summer Haven feels like a different era of Florida. Tucked between the ocean and the Matanzas River, this small historic community has remained one of the most secluded stretches of coastline in northeast Florida. Originally established in the 1800s as a seaside retreat, Summer Haven still retains its Old Florida character, with a mix of historic homes and elevated coastal cottages along a narrow strip of land between the Atlantic Ocean and the Matanzas River. The location offers the rare ability to enjoy both sunrise over the ocean and sunset across the river.  In 2025, St. Johns County completed the Summer Haven Revetment Project, significantly strengthening this section of shoreline. The project included a deep epoxy-coated sheet pile wall driven more than 30 feet into the ground, over 5,800 tons of granite armor stone for storm protection, an elevated concrete roadway, and an advanced drainage exfiltration system to protect homes and infrastructure from future coastal storms. The property offers 150 feet of ocean frontage, with the northern 50 feet preserved as a natural buffer. Private beach access from the rear of the property leads to one of the quietest beaches on this part of the coast, with limited nearby public parking or public access points.  Designed by architect Ron Haase, known for his work on traditional Florida “Cracker” homes that take advantage of Florida's climate and coastal environment. Large windows and elevated living spaces capture sweeping views of the Atlantic.  Located outside the city limits, the property also benefits from lower property taxes while remaining a short drive from St. Augustine. Summer Haven remains one of the last places on Florida’s northeast coast where the pace, landscape, and character of Old Florida still remain.
