Oklahoma's busiest national park unit is a lake and trail country in the south, not a mountain range. Chickasaw National Recreation Area, near Sulphur, had 1,877,797 recreation visits in 2025. Its most visited memorial is smaller and more sombre: the Oklahoma City National Memorial, on the ground where the Alfred P. Murrah Federal Building stood until 19 April 1995.

Not one of Oklahoma's National Park Service units charges an entrance fee. We read the figures below on 27 October 2026 on the National Park Service's pages, the US Fish and Wildlife Service's and the museums' and airports' own sites. The rest come from the Oklahoma Tax Commission's rate chart, the Oklahoma Turnpike Authority, the federal time-zone rules and NOAA's normals.

What do Chickasaw, Washita and the Oklahoma City Memorial charge?

Chickasaw, Washita Battlefield and the outdoor Oklahoma City National Memorial charge no entrance fee. The Park Service lists them as Oklahoma's three units. None is on the 2026 list of eleven parks with a $100 surcharge for visitors from abroad.

The Park Service publishes no visitor count for the Oklahoma City National Memorial, so the table leaves it blank. Its page for the state also lists Fort Smith, which sits on the Arkansas line and is covered on our Arkansas page. Our guide to national park fees for international visitors covers the parks that do charge.

Washita's fee page goes further than the others: the site does not even sell the America the Beautiful pass. Its visitor centre opens daily from 8 a.m. to 4:30 p.m., closed on Thanksgiving, 25 December and 1 January.

A self-guided trail of about 1.5 miles round trip crosses the battlefield, inside the Forest Service's Black Kettle National Grassland. On 27 October 2026 the park's alert list still carried notices from 2023 to early 2026. We could not confirm whether the Fire and Dust Trail has reopened after storm damage.

What does the Memorial Museum charge for a timed ticket?

The Oklahoma City National Memorial Museum charges $18 for an adult, on a timed ticket. Seniors 62 and over and military pay $16, students from age 6 through college $15, and children 5 and under go free. Ticket sales end an hour before closing. The museum says a visit lasts an hour and a half on average.

The museum is not a Park Service fee station. The Oklahoma City National Memorial Foundation owns and runs it without annual federal or state funding. It does not sell or honour America the Beautiful passes. Admission includes free parking in the Memorial garage.

The museum opens Monday to Saturday from 9 a.m. to 5 p.m. and Sunday from noon to 5 p.m., by its own pages. It closes on Easter, Thanksgiving, Christmas Eve, Christmas Day and New Year's Day. On 27 October 2026 the Park Service's alert said the museum stays open during construction until 20 April 2027. The entrance has moved to the southwest corner, and tickets are sold in a temporary Visitor Experience Center.

The outdoor Symbolic Memorial, at NW 6th Street and Harvey Avenue, is free and open 24 hours a day, 365 days a year. Rangers are there daily except Thanksgiving, Christmas and New Year's Day. Drivers of motor homes should note the railroad underpass nearby, with a clearance of 11 feet 11 inches.

What is there to see at Chickasaw National Recreation Area?

Chickasaw National Recreation Area holds the Lake of the Arbuckles, the largest body of water in the park, the Historic Platt District and over twenty miles of trail. Platt was a national park from 1906 to 1976 before it became part of Chickasaw. The Travertine Nature Center sits inside the area too. The outdoor areas never close, and there is no entry fee.

Chickasaw is busiest from late May to September, and July 2025 alone brought 296,004 visits. Summer weekends are much busier than Monday to Thursday, and the quietest months are December to February. Alcohol is banned east of US 177, including at Little Niagara and Bear Falls, from 1 May to 30 September.

The park now has two bison pastures. The east pasture is best seen from Pavilion Springs on the Veterans Trail. On 27 October 2026 its conditions page listed the winter campground schedule. Buckhorn Loops C and D, The Point and Cold Springs were open, Cold Springs by reservation. Buckhorn A and B, Central and Rock Creek were closed.

The Chickasaw Cultural Center, run by the Chickasaw Nation in the same town of Sulphur, opened in 2010. It opens Tuesday to Saturday from 10 a.m. to 5 p.m. and closes on Sunday and Monday. The campus, the Traditional Village and the Honor Garden are free. The Chikasha Poya Exhibit Center charges adults $7; students, seniors 55 and over and military pay $6, and children 12 and under go free.

Sulphur lies about 10 miles east of I-35, between Dallas and Oklahoma City. No public transport reaches the park. Passenger trains stop at Pauls Valley and Ardmore, the Park Service says, with no public transport onward.

Where do bison roam free in the Wichita Mountains?

Bison and longhorn roam free across the Wichita Mountains Wildlife Refuge, just outside the Lawton and Fort Sill area. The refuge charges nothing to visit and opens from sunrise to sunset every day. Its visitor centre opens daily from 9 a.m. to 5 p.m.

President William McKinley set the refuge aside in 1901 as a forest reserve. Bison were returned to it in October 1907. It covers about 59,000 acres, around 90 square miles. Its animals are most active early and late in the day. The Fish and Wildlife Service asks visitors not to approach them.

The refuge has no drinking water, so bring your own. Parking areas and trailheads close from sunset to sunrise, except for fishing. Pets must be on a lead shorter than 10 feet. Groups on the Mount Scott roadway are limited to eight people, when the road is open. We found no opening hours or vehicle limits for that road.

How much of Route 66 runs through Oklahoma?

Route 66 runs for more than 400 miles through Oklahoma, by the count of the Oklahoma Tourism and Recreation Department. The department calls it "the nation's longest driveable stretch" of the road. The Park Service describes Route 66 as "the nation's first all-weather highway linking Chicago to Los Angeles". The full drive, all eight states, is in our road trip Route 66 from Chicago to Santa Monica.

The Oklahoma Route 66 Museum in Clinton, run by the Oklahoma Historical Society, is off I-40 at exit 65. Adults pay $10, seniors 62 and over $8, students aged 6 to 18 $5, and veterans and children 5 and under go free. It opens Monday to Saturday from 9 a.m. to 5 p.m. and closes on 11 November, 26 and 27 November and 24 and 25 December 2026.

The state's tourism site also names the National Route 66 Museum Complex in Elk City and the Route 66 Interpretive Center in Chandler.

The Threatt Filling Station, three miles east of Luther, is a sandstone station built around 1915 that served African American travellers. It joined the National Register in 1995. The station is not open to the public, but can be seen from the road.

An Oklahoma Route 66 Centennial Commission, set up in 2019, exists to celebrate the road's centennial in 2026. Its page gives no date and names no event, so we list none. Our pages on Illinois, where the road began at Grant Park, Missouri and New Mexico cover other stretches of Route 66.

Where can you learn about the 39 First American Nations?

The First Americans Museum in Oklahoma City tells the histories of the 39 First American Nations in Oklahoma today. Its building covers 175,000 square feet in the city's Horizons District. Adults pay $20; tribal citizens, seniors 62 and over, military and students 13 and over pay $15, and children aged 3 to 12 pay $10.

The First Americans Museum closes on Tuesdays. It opens from 10 a.m. to 5 p.m. on Monday and Wednesday to Friday, and from 11 a.m. to 5 p.m. at weekends. Free tours run every day at 11:30 a.m. and 2:30 p.m.

The Chickasaw Cultural Center in Sulphur is described above. The Cherokee Nation's visitor sites in and around Tahlequah did not answer when we tried them. We therefore give no names, hours or prices for them here.

Can you fly to Tulsa or Oklahoma City from abroad?

Tulsa International had its first commercial international flights in 2026, after its customs facility opened on 7 May. Sun Country flew twice a week to Cancún, Mexico, from 21 May to 9 August. Seven carriers fly nonstop from Tulsa to 26 destinations, and every other route is domestic.

Will Rogers International in Oklahoma City lists 28 nonstop cities on its site. Cancún is the only international one, and that route is seasonal. For flights from Europe or Asia, the long-haul gateway is Dallas/Fort Worth in Texas, which lists 77 international nonstop destinations among 193 domestic ones.

From Dallas/Fort Worth airport it is about 193 miles by road to the Oklahoma City National Memorial, and 128 miles to Sulphur and Chickasaw. The Park Service names both Dallas and Oklahoma City as the international airports for Chickasaw.

Can you pay cash on the Turner and Will Rogers turnpikes?

Oklahoma's turnpikes take no cash: all 12 have been cashless since 20 November 2024. The last to convert was the I-44 Will Rogers Turnpike between Tulsa and the Missouri line. The Turner Turnpike between Oklahoma City and Tulsa and the H.E. Bailey Turnpike from Oklahoma City towards Lawton both carry I-44.

PlatePay cameras photograph each plate, and the Oklahoma Turnpike Authority invoices the vehicle's registered owner by mail. A driver can instead pay online about five days after the trip. In a hire car the registered owner is the rental company. Our guide to renting a car in the USA covers how companies pass tolls on.

A PIKEPASS tag gives the lowest toll rate, the authority says. It also works in Kansas, Texas and on some toll roads in Colorado and Florida. We could not read the PIKEPASS and PlatePay sites, so no toll rates or price gap between the two are given here.

How long are the drives between Oklahoma City, Tulsa and Dallas?

The drive from Oklahoma City to Tulsa is about 106 miles, just under two hours on the Turner Turnpike. Dallas is about 205 miles south of Oklahoma City on I-35. The whole state is on Central Time under the federal time-zone rules, and its clocks go back an hour at 2 a.m. on 1 November 2026.

The two Cheyenne distances are the Park Service's own figures; the rest are our own routing without traffic. The drive time from Oklahoma City to Cheyenne is ours. Our routing from Amarillo took a different road, so we give no time for it. The Oklahoma City to Tulsa and Medicine Park legs use turnpikes, which bill by plate.

When is tornado season in Oklahoma?

Oklahoma's tornado season peaks in May, when the National Weather Service office in Norman counts an average of 24.4 tornadoes. That is out of 59.4 a year from 1950 to 2025, with 12.5 in April and 7.6 in June. The Storm Prediction Center puts the southern Plains peak in "May into early June", and adds that tornadoes can happen in any month.

The state had 152 tornadoes in 2024 and 106 in 2025, well above the long average. May is also Oklahoma City's wettest month, with 5.31 inches of rain.

October73°F / 49°F74°F / 51°F77°F / 50°F73°F / 43°F

The table gives NOAA's 1991 to 2020 average highs and lows at four airport weather stations. Oklahoma City reaches 90°F or more on about 73 days a year and gets 6.7 inches of snow. Lawton's airport, the nearest to the Wichita Mountains, passes 90°F on about 101 days. Guymon, in the Panhandle at 3,123 feet, has about 122 nights a year at or below freezing.

Will Tulsa's hotel tax rise in 2027?

Tulsa's hotel tax will rise from 5% to 9.9% on 1 January 2027 if voters approve it on 3 November 2026. The City Council says it would be the first such change in more than 40 years. It would cover hotels, motels, inns and short-term rentals such as Airbnb or Vrbo. On 27 October 2026 the result was a week away, so check it before booking.

Oklahoma's state sales tax is 4.5%, and cities and counties add their own. Tulsa's own page gives 8.517% inside the city limits: 4.5% for the state, 0.367% for Tulsa County and 3.65% for the city. In the Oklahoma County part of Oklahoma City the rate is 8.625%, our sum of the Tax Commission's city and county shares.

The same October to December 2026 chart gives these totals, also our own sums: Lawton and Medicine Park 9%, Sulphur, Tahlequah and Clinton 9.5%, and Cheyenne 9%. Parts of Oklahoma City in other counties pay more, up to 10.12% in its Pottawatomie County part. The chart lists lodging taxes of 5.5% in Sulphur and 4% in Tahlequah.

We could not confirm Oklahoma City's hotel tax, because the city's site did not answer. We also could not confirm whether the sales tax applies to a hotel room on top of the lodging tax. Our guide to sales tax in the USA explains why prices are shown before tax.

Questions before you go

  • Does the Oklahoma City National Memorial charge admission?

    The Oklahoma City National Memorial's outdoor Symbolic Memorial is free and open 24 hours a day, 365 days a year. The Memorial Museum beside it is run by the Oklahoma City National Memorial Foundation, not the Park Service, and sells timed tickets at $18 for an adult, $16 for seniors 62 and over and military, and $15 for students. The museum does not sell or honour the America the Beautiful pass.

  • Is any Oklahoma park on the $100 non-resident surcharge list?

    None of the state's parks is on the 2026 list of eleven parks that charge visitors from abroad a $100 surcharge. Chickasaw National Recreation Area, Washita Battlefield and the outdoor Oklahoma City National Memorial charge no entrance fee at all, and the Wichita Mountains Wildlife Refuge is free too. The $250 non-resident annual pass buys nothing on an Oklahoma-only trip.

  • How many miles of Route 66 are in Oklahoma?

    Route 66 runs for more than 400 miles across Oklahoma, according to the state's tourism department, which calls it the nation's longest driveable stretch of the road. The Oklahoma Route 66 Museum in Clinton, off I-40 at exit 65, charges $10 for an adult and opens Monday to Saturday from 9 a.m. to 5 p.m.

  • When is tornado season in Oklahoma?

    The state's tornado season peaks in May, when the National Weather Service in Norman counts an average of 24.4 tornadoes, out of 59.4 a year from 1950 to 2025. April averages 12.5 and June 7.6. The Storm Prediction Center puts the southern Plains peak in May into early June, and warns that tornadoes can happen in any month.

  • How do you pay tolls on Oklahoma turnpikes without a PIKEPASS?

    Oklahoma's turnpikes bill drivers without a PIKEPASS through PlatePay, since all 12 went cashless on 20 November 2024. A camera photographs the plate and the turnpike authority invoices the vehicle's registered owner by mail, or the driver pays online about five days after the trip. In a hire car the registered owner is the rental company.
