Typically Christmas decorations start to go up around the last week of October – yes, sometimes you'll see snow on the castle at Disneyland on Halloween night!
Top holiday entertainment at Disneyland includes A Christmas Fantasy parade, Believe… In Holiday Magic Fireworks, World of Color- Seasons of Light, and light shows on Sleeping Beauty's Castle.
For this show I recommend seeing it from this location if you can handle the crowds. I recommend bringing some snacks and some patience. Bring an easily foldable blanket to just and mark off your space
Wintertime Enchantment at Sleeping Beauty's Winter Castle
Every evening there is a lighting ceremony in front of the castle which includes a brief snowfall of snow. This ceremony typically occurs at 7:30PM and 8:30PM every night.
Twice a day a celebration featuring Disney and Pixar characters offer a dance party with Mickey Mouse to the merry rhythms of the Holiday Toy Drummers. You can find this dance party at the Paradise Gardens Park Obelisk and Carthay Circle.
