Tallgrass Prairie Preserve

Experience the largest protected remnant of tallgrass prairie on Earth.

About

Experience the largest protected remnant of tallgrass prairie on Earth. Located in Oklahoma's picturesque Osage Hills, the Joseph H. Williams Tallgrass Prairie Preserve encompasses nearly 45,000 acres, offering a breathtaking glimpse into an ecosystem that once covered vast expanses of North America but now remains as less than four percent of its original size. Managed by The Nature Conservancy, this living landscape is a testament to natural cycles, where free-ranging bison and prescribed fire work in harmony to restore and maintain its incredible biodiversity.

The preserve is a thriving habitat for over 2,500 American bison, one of the largest privately owned herds, providing an iconic sight as they roam the rolling hills. Visitors can drive a 15-mile loop through the bison unit, often observing these magnificent creatures up close from the safety of their vehicles. Beyond the bison, the preserve boasts over 700 plant species, including towering Big Bluestem, Indiangrass, and vibrant wildflowers like the Pale Purple Coneflower and Maximilian Sunflower. Birdwatchers will delight in spotting more than 300 species, such as the elusive Greater Prairie-Chicken and the distinctively tailed Scissor-tailed Flycatcher, while mammals like White-tailed Deer, Bobcat, and Armadillo also call this prairie home.

A visit to the Tallgrass Prairie Preserve is an immersive journey into a vital, almost vanished ecosystem. It offers unparalleled opportunities for wildlife photography, serene nature hikes, and a profound connection to the land and its history. The vast, open skies and sweeping panoramas create a memorable experience, whether you're observing bison graze, listening to the calls of prairie birds, or simply absorbing the tranquil beauty of the tall grasses swaying in the breeze.
