Rainbow River in 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.
