In the 1920s, this spring was a favorite spot for tourists and locals. As the attraction grew, the river was dredged for glass bottom boat tours; and waterfalls were built on piles of phosphate tailings. A zoo, rodeo, gift shops and a monorail with leaf-shaped gondolas were added. In the mid-1970s, when larger theme parks lured the tourists away, Rainbow Springs was closed. In the mid-1990s, it reopened as a state park. In 1972, the U.S. Department of the Interior designated Rainbow River as a National Natural Landmark. It is also an aquatic preserve and an Outstanding Florida Water.
Rainbow Springs has served as an important natural resource for humans and animals for many years. At one time, mastodon and mammoth fossils were found in the Rainbow River, along with relics of the American Indians who used the river for transportation and fishing. Much later, in the early 20th century, men began mining the surrounding area for phosphate. The new industry brought a boom and the towns of Juliette and Dunnellon were founded. Juliette, once located on what is now park property, no longer exists, but Dunnellon continues to be an active community, welcoming visitors to enjoy area gems such as Rainbow Springs State Park.
The privately owned Rainbow Springs attraction opened in the 1930s, joining the ranks of family oriented venues that were bringing a great deal of tourism to Florida. The major highways in the state at the time were U.S. 1 on the east coast, U.S. 41/441/27 through the center of the state and U.S. 19 on the west coast. Attractions were often built along these highways and capitalized on the natural beauty of Florida, especially its springs. Before the building of the attraction, the Rainbow River was known at different times as Wekiwa Creek or Blue Run. 'Rainbow River' seemed more marketable and the names of the river and springs were changed to the names they bear today.
One of the features that separated Rainbow Springs from similar attractions was the way that visitors could view the spring bottom. Most springs offered some form of glass bottom boat ride, enabling visitors to view the spring through the clear glass floor. But at Rainbow Springs the distinctive sub-boats had stairs that went below the waterline of the boat and visitors could look out at eye level. The boats were steered by a captain who told the story of the springs and the creatures that called the springs home.
Another feature found only at Rainbow Springs was the Leaf Ride, a monorail system used to transport visitors through the park at tree level. This feature was added to the park in the 1960s. Visitors enjoyed viewing a large aviary, three waterfalls, a rodeo, a small zoo complex and an historic garden. The ownership of the Rainbow Springs attraction changed hands several times, and at one time was owned by S&H Green Stamps and Holiday Inn. The development of the interstate highway system in Florida eventually led to the demise of Rainbow Springs. The interstate passed by the small towns that hosted such attractions and newer, modern attractions in Orlando drew many away from the older parks. By 1974, Rainbow Springs was closed and the facilities fell into disrepair. In 1990, following petitioning by concerned citizens on behalf of the attraction, the state of Florida purchased Rainbow Springs. It opened to the public as a state park on a full-time basis in 1995.
On October 25, 1990, Rainbow Springs State Park joined the Florida Park Service. The spring was saved from direct encroachment and in the process a part of Florida history was preserved as well. The citizens that supported the acquisition of the park soon formed the park's Citizen Support Organization, called Friends of Rainbow Springs, Inc. This organization led the way in opening the park by physically clearing paths and bringing life back to the gardens and other features. By 1993, state funding allowed for park staff to join the volunteers. Today, the park consists of more than 1,470 acres and has three main entrances. The main park entrance is still on U.S. 41 and at the headsprings of the Rainbow River. The campground and tubing entrance are about seven miles away, by car. Both of these areas have new facilities and open up new recreational opportunities for park visitors. Stop for a visit and experience the Real Florida at Rainbow Springs State Park.
