Deep in America’s heartland, this preserve protects the largest area of tallgrass prairie remaining on Earth. Though these grasses once covered 170 million acres of the country, only a small fraction of this type of prairie remains.

The vast majority of America’s tallgrass prairie has been destroyed by agriculture, but the flint and limestone bedrock of the Flint Hills made the land unsuitable for agriculture, protecting the prairie. Now, visitors can stand amid nearly 11,000 acres of rustling grasses and watch the sea of green blades ripple under a vast blue sky. For those lucky enough to visit in the spring, the preserve is also a top spot to see wildflowers, and the sunsets are dazzling year-round.
