Emerald Paradise Rainbow Springs Florida’s third largest spring, Rainbow Springs pump 600 million gallons of water daily and serves as the headwater to the pristine Rainbow River. The property was acquired by the State Park Service in 1990 and is slowly being allowed to revert to its natural state. Beautiful floral gardens surround the spring, and the area is immensely popular in the spring when the azaleas are in bloom. The state also acquired Rainbow Springs State Campground, located nearby, which was formerly privately owned. From the campground, you can tube or canoe the crystalline waters of Rainbow River, or fish for largemouth bass and other freshwater species. A nature trail provides a lovely walk past two waterfalls and the azalea gardens, and meanders along the Rainbow River.
