Rainbow River, Rainbow Springs State Park, Florida, United States

Nestled in the northern Gulf Coast of Florida in the United States is Rainbow Springs State Park. This area has served as a natural resource for humans and animals for centuries, with the crystal-clear Rainbow River—flowing through the park—playing a major role. The gently winding waterway is fed by Rainbow Springs, one of Florida's largest springs. The water that bubbles up here comes from an almost 200,000-hectare area and eventually flows into the Withlacoochee River.

The Rainbow River's transparent waters are perfect for swimming and snorkelling, and they maintain a constant temperature of 22°C year-round. The park's history dates to the late 1880s, when hard rock phosphate was discovered in the area, leading to the boomtown era. This period saw the rapid growth of a small community called Juliette near the springs, driven by the phosphate mining industry. During the 1960s, the park emerged as a popular tourist destination, featuring glass-bottom boat rides, a monorail system and even a rodeo. Today, visitors can explore the ornamental gardens, waterfalls, walking paths and enjoy the diverse wildlife that calls Rainbow Springs home.
