Space Mountain at Disneyland has been running since May 27, 1977. That makes it 48 years old and approaching its 49th birthday in a few weeks. For nearly five decades, Disney guests have been boarding that ride in the dark, and the experience has remained compelling through every era of theme park development that followed its debut. That kind of longevity does not happen by accident, and one of the ways Disneyland has kept a nearly fifty-year-old coaster feeling relevant is the Hyperspace Mountain overlay that transforms it into a Star Wars battle sequence for a limited window each spring.
A new permit filing just confirmed exactly when that window opens and closes in 2026, and the timeline is more specific than anything Disneyland had previously confirmed publicly.
What the Permit Actually Says
According to city records, Disneyland has filed to install the specialized Hyperspace Mountain marquee overlay starting around April 17. The permit is set to expire on June 1. Hyperspace Mountain officially launches on April 28, which means the actual guest-facing Star Wars experience runs from late April through the end of May, approximately six weeks on the 48-year-old coaster before the standard Space Mountain identity returns.
This is the first concrete end-date information for the 2026 Hyperspace Mountain run. Previous announcements confirmed the April 28th return but the June 1st permit expiration gives guests the clearest picture yet of how long the window actually lasts.
What Hyperspace Mountain Does to Space Mountain at Disney
The overlay takes the classic Space Mountain infrastructure and replaces the ambient cosmic audio and visuals with a full Star Wars battle sequence. Guests find themselves in a Rebel fleet engagement, dodging TIE fighters and weaving around Star Destroyers with a cinematic soundtrack that pulls the experience directly into the Star Wars universe. The ride itself does not change. The darkness, the speed, and the unpredictable turns are all still there. What changes is everything surrounding those physical sensations, and the result is significant enough that guests who specifically seek out Hyperspace Mountain during its seasonal run are not wrong to treat it as a different experience from standard Space Mountain.
The overlay has run during Season of the Force for years and the April 28th return date for 2026 lands precisely within the window that traditionally encompasses May the 4th celebrations.
The Bigger Star Wars Picture at Disneyland This Spring
The Hyperspace Mountain permit is one piece of a larger Star Wars programming picture that Disneyland is assembling for spring 2026, and the full scope of what is coming makes the six-week Hyperspace Mountain window feel like just the opening act.
On May 22, Millennium Falcon: Smugglers Run will debut an entirely new mission inspired by The Mandalorian and Grogu. That update replaces the Hondo Ohnaka cargo-running storyline, which has been the foundation of the attraction since Galaxy's Edge opened, bringing new characters, visuals, audio, and a new mission objective to a ride that has been running the same experience since the land debuted. The May 22 date aligns with the theatrical release of a new Star Wars film the same weekend, creating a level of cross-platform programming alignment that Disney has been building toward across both the parks and the franchise.
The overlap between the Hyperspace Mountain permit expiring June 1 and the new Smugglers Run mission launching May 22 creates approximately 10 days when both experiences are available at Disneyland. For guests planning a spring visit, that late May window is the period when every piece of the Star Wars programming puzzle is running at the same time.
Why the Disney Permit Matters for Planning
The June 1st expiration date answers the question that Disneyland had not explicitly confirmed before this filing. Guests who want Hyperspace Mountain have until approximately June 1. Those who want the new Smugglers Run mission should plan for May 22 or later. Guests who want both should target the late May window where the overlap exists.
Space Mountain turns 49 this May. The version running on that birthday will be navigating a Star Wars battle. The permit confirms how long that lasts.
