If you haven't visited Frontierland at Magic Kingdom in a few years, you might be surprised by just how much has changed.
And Disney isn't close to finished.
The land that generations of Walt Disney World guests knew is being reshaped through attraction replacements, major refurbishments, permanent closures and completely new construction.
Even some of Frontierland's newest additions are already getting adjustments.
Disney has now changed the operating hours for McKim’s Mile House, its Disney Vacation Club Member Lounge near Country Bear Musical Jamboree.
It's a relatively simple operational update. But zoom out from that one building, and you can see just how extensive Disney's Frontierland overhaul has become.
Another Change for McKim’s Mile House
Disney Vacation Club members can now visit McKim’s Mile House between 10:00 a.m. and 7:00 p.m. daily.
The previous schedule ran from 11:00 a.m. until 8:00 p.m., meaning Disney has shifted the entire operating window forward by one hour.
This marks the second adjustment to the lounge's schedule since opening. Disney previously extended its operating hours in January 2026.
McKim’s Mile House gives eligible DVC members and their guests somewhere to recharge during a park day. Disney offers seating, complimentary soft drinks, Wi-Fi and charging cords upon request. Member Services Advisors are also available inside.
It's one of Frontierland's newer experiences, but the surrounding area has been changing at a much faster pace.
Disney Has Been Reworking Frontierland for Years
One of the first major moves involved Splash Mountain.
The attraction permanently closed in 2023, ending its decades-long run at Magic Kingdom. Disney subsequently transformed the ride into Tiana’s Bayou Adventure, which opened in 2024.
Then Disney turned its attention to another Frontierland original.
Country Bear Jamboree closed and returned as Country Bear Musical Jamboree. The bears remained, but Disney introduced an entirely different production centered around new interpretations of familiar Disney songs.
Big Thunder Mountain Railroad eventually joined the list.
Disney closed the coaster in January 2025 for a major refurbishment that stretched into 2026. The attraction reopened in May with refreshed elements and new storytelling.
Yet those projects look relatively contained compared with what Disney is building next.
Disney Removed a Huge Piece of Magic Kingdom
For decades, Rivers of America and Tom Sawyer Island helped define Frontierland.
That's no longer the case.
Disney permanently closed the Rivers of America, Tom Sawyer Island and Liberty Square Riverboat in July 2025.
The closures cleared the way for one of the most ambitious changes in Magic Kingdom's history.
Disney is developing Piston Peak National Park, an original area inspired by Pixar's Cars (2006).
The project will feature two new attractions.
One will send guests on an off-road adventure through rugged terrain. Disney is also planning a second experience geared toward families and younger visitors.
Perhaps more importantly, Piston Peak will physically change what Frontierland looks like.
The river views that existed for decades are being replaced by a completely new environment featuring mountains, trees, waterways and other scenery.
It's hard to imagine a more literal Frontierland overhaul than removing an entire river and island to build a new themed environment.
Villains Land Makes the Transformation Even Bigger
Disney isn't stopping with Piston Peak.
Villains Land is also planned for the area beyond Big Thunder Mountain Railroad.
Disney has confirmed that the expansion will include two major attractions, dining and shopping.
That development will eventually push Magic Kingdom farther beyond its existing boundaries and turn Frontierland into an important gateway.
Guests moving through this side of Magic Kingdom will eventually encounter a substantially different collection of experiences.
Tiana’s Bayou Adventure and the refreshed Big Thunder Mountain Railroad will remain major anchors. Piston Peak will occupy space previously dominated by Rivers of America and Tom Sawyer Island. Villains Land will rise beyond the existing Frontierland footprint.
The scale is enormous.
Frontierland's Overhaul Is Already Happening
There's still plenty of construction ahead, but guests don't have to wait for Frontierland's transformation to begin.
It already has.
Disney has replaced Splash Mountain, reimagined Country Bear Jamboree, refurbished Big Thunder Mountain Railroad, opened McKim’s Mile House and permanently removed three longtime experiences.
Now the company is preparing two new Cars attractions and an entirely separate Villains Land nearby.
Against that backdrop, McKim’s Mile House moving to a 10:00 a.m. to 7:00 p.m. schedule is another small adjustment in a land experiencing much bigger changes.
Frontierland isn't disappearing completely. Several familiar pieces will remain.
But the version waiting on the other side of Disney's current construction projects will look very different from the Frontierland guests knew just a few years ago.
And with some of Magic Kingdom's largest projects still ahead, this overhaul is far from finished.
