When night falls over Disney California Adventure Park, something thrilling awakens inside the Collectorās Fortress. Guardians of the Galaxy ā Monsters After Dark has returned, bringing an electrifying twist to the fan-favorite Mission: BREAKOUT! attraction. Just when you thought this ride couldnāt get any better, Disney has managed to pack two experiences into one, offering guests a chance to enjoy both the upbeat daytime adventure and the darker, more mischievous after-dark version in the same day. This unique Halloween overlay kicks off each evening (we enjoyed it for the first time during this year’s Oogie Boogie Bash), and transforms the Guardiansā wild escape into a pulse-pounding rescue mission thatās every bit as fun as it sounds.
The beauty of this attraction lies in its infectious energy: connectable characters, a lively rock soundtrack, and that signature Marvel-style chaos that somehow feels cheerful in all the right ways. By day, guests join Rocket to free his friends from the Collectorās grasp. By night, itās pure adrenaline as Rocket returns to save Baby Groot from a horde of escaped creatures running wild through the fortress. The soundtrack shifts, the lighting deepens, and the tone turns just spooky enough to make this experience feel brand new, even for guests whoāve ridden dozens of times before. Even the queuing area has this eerie red glow that sets the scene for the adventure ahead.

Unlike other beloved overlays such as Haunted Mansion Holiday or “itās a small world”-Holiday, which take weeks to install and replace the attraction entirely for the season, Monsters After Dark switches seamlessly from day to night, letting guests enjoy both versions interchangeably. Itās an impressive feat of Disney Imagineering and one that perfectly captures the spirit of the season; clever, creative, and full of surprises. This special Halloween version runs through October 31st, so make sure to catch it while you can. Whether youāre a longtime Marvel fan or just love a good scream set to a killer soundtrack, this limited-time overlay is a canāt-miss highlight of the Disneyland Resort Halloween festivities.
