Oklahoma’s free national park once drew more visitors than Yellowstone

It’s older, wilder, and free to enter

Southern Oklahoma has a park that most Americans have never heard of, and it pulls in 1.6 million visitors a year.

Chickasaw National Recreation Area covers nearly 10,000 acres in the Arbuckle Mountain foothills, with mineral springs, natural swimming holes, a 36-mile lake, and a bison herd that’s been there since the early 1900s.

It costs nothing to walk in. What it has taken more than a century to build is harder to put a price on.

When this park outpaced Yellowstone and Yosemite

In 1914, more people came here than to Yellowstone or Yosemite. That’s not a typo.

Two railroad lines ran directly into the town of Sulphur, and visitors poured in for the mineral springs. Congress had made it Platt National Park in 1906, the seventh national park in the country and the smallest.

In 1976, it merged with the Arbuckle Recreation Area and was renamed to honor the Chickasaw Nation, whose people had called this place home long before the federal government arrived.

The Chickasaw and Choctaw knew what they had

Long before European settlement, the Chickasaw and Choctaw nations gathered at these springs. Local tradition called it “the peaceful valley of rippling waters.”

By the late 1800s, private developers were eyeing it, the same way they’d moved in on Hot Springs, Arkansas.

To keep that from happening, the tribes sold 640 acres to the federal government in 1902, creating what would become Sulphur Springs Reservation. That decision protected the land.

Without it, the springs might have ended up behind a resort fence.

Jump the ledge at Little Niagara Falls

The most popular spot in the park is Little Niagara Falls, where Travertine Creek runs over rock ledges into a natural pool below.

The water comes out of the ground at 62 to 64 degrees year-round, so on a 100-degree Oklahoma afternoon, it hits like a cold shower. You can wade, splash, or jump from the ledges.

The 22-acre area around it includes stone picnic tables and benches built in the 1930s. Bear Falls and Garfield Falls sit nearby, both visible from the road.

More than 20 springs push up through ancient rock

The springs here come from the Arbuckle-Simpson aquifer, a body of underground water stretching beneath more than 500 square miles of south-central Oklahoma.

The EPA has designated its eastern section a Sole Source Aquifer, meaning it’s the only practical water supply for the area.

Freshwater springs like Antelope Springs and Buffalo Springs feed Travertine Creek, while mineral springs push up sulphur, bromide, and iron-rich water. The park has more than 20 named springs.

Some are safe to touch. Others, the NPS warns, are not safe to drink.

The CCC spent seven years reshaping this land

Between 1933 and 1940, about 200 workers from Civilian Conservation Corps Company 808 built most of what you’ll walk through today.

They laid stone pavilions, dug campgrounds, cut trails, and built small dams along Travertine Creek. They planted more than 500,000 trees and set up the bison pasture that still runs today.

Most of their stonework stands exactly as they left it, built in the National Park Service rustic style using local rock and timber.

In 2011, the Platt National Park Historic District earned designation as a National Historic Landmark.

A small bison herd grazes where the CCC planted trees

A bison herd has roamed the Platt Historic District since the early 1900s, rotating between an east and west pasture depending on the season. Signs along Highway 177 tell you which pasture they’re in.

The Bison Pasture Trail runs 1.9 miles as a moderate loop and gives you the best shot at seeing them up close. You might also come across white-tailed deer, wild turkeys, and armadillos along the way.

The park asks that you stay in your vehicle or keep a safe distance on foot.

The limestone bridge that made it onto a quarter

Lincoln Bridge is a limestone arch built in 1909 to mark the 100th birthday of Abraham Lincoln. It’s the oldest developed structure from the Platt National Park era, designed by park ranger Forrest Townsley.

The bridge connects Flower Park to the mineral springs on the south side of Travertine Creek. In 2011, the U.S. Mint put it on the America the Beautiful quarter for Oklahoma.

Nearby, the Vendome Well, drilled in 1922, was once reported as the largest artesian well in the state.

A 2,350-acre lake built for fishing and open water

The southern section of the recreation area is a different world from the springs. Lake of the Arbuckles covers 2,350 acres with 36 miles of shoreline.

The Bureau of Reclamation built it in 1966 by damming Rock Creek, and it also supplies drinking water to the city of Ardmore.

The water runs clear, and the Oklahoma Department of Wildlife Conservation has ranked it among the state’s best bass fishing lakes. You can boat, kayak, water ski, swim, or camp along the shore.

A permit is required for motorized watercraft.

More than 20 miles of trails cut through the park

If you want to stay on foot, the park gives you options.

The Buffalo and Antelope Springs Trail starts at the Travertine Nature Center and follows the creek for about 1.2 miles round trip through shaded forest.

The Bromide Hill Trail climbs switchbacks up to a hilltop with wide views of the surrounding landscape. For mountain bikers and horseback riders, the Rock Creek Multi-Use Trails run through more remote terrain.

The Veterans Lake Trail is a paved loop around a 67-acre lake, built in 1933 and ringed by trees.

Start at the nature center, then hit the trail

The Travertine Nature Center, built in 1969, has an architectural style influenced by Frank Lloyd Wright, low lines and natural materials that sit easy against the landscape.

Inside, you’ll find exhibits on the park’s geology, springs, and wildlife, including live animal displays. Rangers run guided walks, talks, and Junior Ranger programs, many launching from here.

A short film called “By the Ripping Water” covers the park’s history before you head out. The nature center also sits right at the trailhead for the Buffalo and Antelope Springs Trail.

The park took a hit in 2024 but it’s still running

An April 2024 tornado tore through the park, knocking down trees and damaging structures across the area. NPS crews and contractors have been clearing debris and making repairs ever since, with work continuing into 2026.

Most of the park has reopened. The springs still flow, the creek still runs, and the bison still graze.

Before you go, check the park’s official website or social media for any closures that might still be in effect. Entry remains free.

Camping and boat launch permits carry fees.
