Watch one of Austin's most joyful landmarks flicker to life beneath a historic moonlight tower. The 155-foot Zilker Holiday Tree wraps more than 3,300 colorful bulbs into a glowing spiral that invites visitors to stand underneath, look up, and take a dizzying holiday spin. Opening night adds live music from the Austin Civic Wind Ensemble and the official lighting ceremony, while the tree remains illuminated nightly through New Year's Day for free family visits and festive photos.
