Nestled in the northern Gulf Coast of Florida, 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 a more than 1,800-square-kilometre 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 over 20°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 and walking paths and enjoy the diverse wildlife that calls Rainbow Springs home.
