Rainbow River in Florida is a "first-magnitude" spring-fed river famous for its crystal-clear water and diverse freshwater ecosystem. The river is teeming with Largemouth Bass, Suwannee Bass, and Bluegill (Bream), making it a favorite for catch-and-release anglers. You will also frequently see Bowfin (Mudfish) and the prehistoric-looking Longnose Gar lurking near the eelgrass beds. For snorkelers and kayakers, the most vibrant sights are the schools of Redbreast Sunfish and various types of Turtles (like the Florida Red-bellied Cooter) that share the water. Because the water stays a constant 72°F (22°C) year-round and is exceptionally clear, it provides an aquarium-like view of the fish's behavior. It is important to note that while fishing is allowed in certain sections, the upper part of the river within the Rainbow Springs State Park is a protected area where you can observe the fish in their natural, undisturbed habitat, contributing to the river's reputation as one of the most beautiful natural wonders in the southeastern United States.
