Christmas in Pasadena Tree Lighting kicks off the holiday season at the Pasadena Public Library: Central in Pasadena, just outside Houston. Bundle up and join the community for vendors, live entertainment, food trucks and lighted holiday scenes. There's a snow slide for the kids, and Santa and Mrs. Claus are waiting inside the library. It's free, it's family-friendly and it's a festive evening that feels like a winter wonderland.
