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.
