Frontier City is a western-themed Six Flags park in Oklahoma City that mixes wooden and steel coasters with splash rides, spinning thrill rides, and a dedicated kids’ area, which means riders of very different sizes are all trying to plan the same day. Knowing a ride’s minimum height before you’re standing in line saves a disappointed kid, a wasted wait, and a scramble to find a rider-swap plan on the fly.
This guide organizes Frontier City’s height minimums by tier, in inches and centimeters, based on the specs listed on each ride’s official page at sixflags.com/frontiercity. It covers nearly every ride in the park rather than a partial sample — ride lineups, seasonal openings, and posted minimums can change, so treat Six Flags’ official height and ride pages as the final word before you go.

Height Requirements, Tier by Tier
48 inches (122 cm) and up: Silver Bullet, Diamondback, Rolling Thunder (formerly Brain Drain), Gunslinger, Prairie Schooner, Rodeo Round Up, Gully Washer, and Tin Lizzy’s all require riders to be at least 48 inches (122 cm) tall — this tier covers the park’s biggest coasters, its fastest spinning and swinging thrill rides, the Gully Washer water slides, and the Tin Lizzy’s antique cars.
42 inches (107 cm): Wildcat, the park’s classic wooden coaster, along with Frankie’s Mine Train, Ol’ 89er Express, Quick Draw, the Grand Centennial Ferris Wheel, the Grand Carousel, Soaring Eagle, Casino, Mystery River Log Flume, and Rocky’s Ranger Planes all open at 42 inches (107 cm) — the park’s largest tier, and a good target zone for kids stepping up from family rides into first coasters and thrill rides.
38 inches (97 cm): Steel Lasso and Renegade Rapids set their minimum at 38 inches (97 cm), a middle tier aimed at younger riders who are ready for a gentler coaster or a water ride.
36 inches (91 cm): Sidewinder, Winged Warrior, Wild West Water Works, Billy’s Frog Hopper, Tornado, Bubba’s Honey Swings, and Tina’s Tea Cup Twirl have the park’s lowest posted minimums at 36 inches (91 cm), making them the most accessible options for smaller kids and families.
Hootie’s Tree House is the one Frontier City attraction that’s an open-play area without a posted minimum height, so it’s worth building into your plan for riders who haven’t hit 36 inches yet. Frontier City lists 28 total attractions across coasters, thrill rides, family rides, kids’ rides, and water attractions; 27 of them have a posted height minimum verified on official ride pages, and the park’s full attractions page is the place to confirm any seasonal changes.
Tips for Families Visiting Frontier City
Measure kids at home before you go — stand them against a wall, mark the height, and check it against this guide’s tiers so you know which lines are realistic before you’re at the park. Six Flags parks generally check height at each individual ride’s entrance rather than at the main gate, so a child can be cleared for some rides and not others on the same visit.
If a child comes up just short, look at the 36-inch and 38-inch tiers first — Sidewinder, Winged Warrior, Wild West Water Works, Billy’s Frog Hopper, Tornado, Bubba’s Honey Swings, Tina’s Tea Cup Twirl, Steel Lasso, and Renegade Rapids give the most options below 42 inches. For riders in the 42–48 inch range, Six Flags’ companion policy requires a supervising companion at least 54 inches tall and roughly 14 years or older to ride alongside them on rides that call for it; confirm which specific attractions require a companion using the posted signage or the official ride pages, since not every ride in this range requires one.
For a mixed-height group, plan around one adult riding with the group while a second adult uses rider swap (ask a ride attendant) to wait with anyone who doesn’t meet the minimum — that way nobody has to skip the ride entirely.

Frontier City Height Requirements FAQs
What is the minimum height to ride at Frontier City?
The lowest posted minimum is 36 inches (91 cm), required for rides like Sidewinder, Winged Warrior, and Tina’s Tea Cup Twirl. Several of the park’s biggest attractions, including Silver Bullet, Diamondback, and Rolling Thunder, require 48 inches (122 cm).
Can kids under 42 inches ride anything at Frontier City?

Sidewinder, Winged Warrior, Wild West Water Works, Billy’s Frog Hopper, Tornado, Bubba’s Honey Swings, and Tina’s Tea Cup Twirl are open to riders as short as 36 inches (91 cm), and Steel Lasso and Renegade Rapids open at 38 inches (97 cm). Hootie’s Tree House, an open-play area, has no posted height minimum at all.
Does Frontier City measure height at the gate or at each ride?
Like other Six Flags parks, Frontier City checks height at each ride’s entrance rather than at the main park gate, so a child’s clearance can vary ride by ride. Bring a measurement from home as a guide, but expect staff at each attraction to do the official check.
