What time does the castle light up frozen

At dusk

Dark

The times may vary depending on the events that day. You can check that and other shows time with "My Disney Experience" app

Castle lights up multiple times each night. 6:30pm, and then again at 9pm, and 10:30. Each for a light show or parade

I think was like 844 pm and the parade was about 930..

As soon as it gets dark outside, it will light up. The time varies depending on the sunset.

The frozen show is promptly 30 minutes after the park close

1015pm on magical night
