Rainbow Springs State Park is a Florida State Park located on U.S. 41, three miles (5 km) north of Dunnellon, Florida. It comprises 1,459.07 acres upland and 12.83 acres submerged. The most significant natural feature is the first magnitude headspring basin which produces up to 600,000,000 US gallons of fresh water per day, forming The Rainbow River. The looking glass waters of Rainbow Springs come from several vents, not one large bubbling spring.
