Twin Rivers Sec is a residential area in Satsuma, a small Putnam County community on the eastern side of the St. Johns River between Palatka and Crescent City. This is river and lake country, with Crescent Lake to the south, low wooded land, and waterways that have long drawn anglers and boaters to this part of Florida. The setting is rural and unhurried, with homes set along local roads rather than in dense subdivisions, and lot sizes and housing ages varying across the area. Satsuma provides basic local services, while Palatka to the north offers the wider range of schools, shopping, and medical care for this part of Putnam County. US 17 and State Road 309 run through the surrounding corridor, connecting Satsuma with Welaka, Crescent City, and the rest of the river region. Browse current Twin Rivers Sec homes for sale below.
