In 2026, Disneyland Resort’s "Halloween Time" follows its established tradition of running from late August through October 31. The hauntingly beautiful decor—including the iconic giant Mickey Pumpkin on Main Street, orange bunting, and countless hand-carved Jack-o'-lanterns—remains in place through the final night of the season. Almost immediately after the park closes on Halloween night, a massive "overnight transformation" begins. By the morning of November 1, much of the spookier decor is removed to make way for the Holiday Season, which typically begins its soft launch in early November. However, some specific themed elements, like the "Plaza de la Familia" (celebrating Coco and Día de los Muertos), often remain through November 2 to observe the traditional holiday. If you are visiting in late October, you can expect the full Halloween atmosphere, but be prepared for the pumpkins to vanish and the Christmas garlands to start appearing the moment the calendar turns to November.
