Every year Lago Vista hosts the Annual Christmas Tree Lighting. Kids young and old join together to watch dancers and singing groups on stage with festival Christmas carols filling the night air. Businesses, nonprofit groups, and churches donate their time and delicious treats, providing a simple meal for all to enjoy. The big moment comes when the City tree is lit up along with all light in the City at the same time. And then, arriving on a big red fire truck with lights flashing and horns blaring, Santa and Mrs. Clause delight the children with fill-in letters to Santa, a chance to whisper in his ear what they want for Christmas, and free photos with Santa, Mrs. Clause, and his Elf.
