The holiday season in Katy: where to celebrate, what to verify

Katy's holiday season has a dependable shape even though the specific dates move every year. The pattern: the City of Katy lights the tree at Historic Town Square in early December, the Katy Old-Fashioned Christmas Festival fills Historic Downtown Katy on a December Saturday, Katy Mills runs a big indoor holiday experience, and the neighborhoods around Cinco Ranch add their own market days and celebrations. This guide covers what to expect, and where to verify this year's dates, because the official 2026 calendar was still being finalized when this was published.

Historic Downtown Katy: the tree lighting

The City of Katy has held its annual Christmas Tree Lighting at Historic Town Square in the first week of December in recent years: a free early-evening event with a story reading, local choirs and dance groups, Santa, letters to Santa, and cookie decorating. It is the night the season officially starts for the city, and the square fills up, so arriving a little early is worth it.

Exact dates for 2026 were not yet published when this guide went live. The City of Katy's official calendar and its news page, both linked below, are the sources to watch, so you can confirm the night rather than trust a roundup.

The Katy Old-Fashioned Christmas Festival

On a December Saturday, the Katy Old-Fashioned Christmas Festival takes over Historic Downtown Katy, in recent years on the first Saturday of the month. It is free and family-friendly: Katy Market Days vendors set up along the street, food trucks line the blocks, and carriage rides and Santa photos are part of the routine. Once you park, the whole thing is walkable.

Katy Mills and the indoor holiday experience

Katy Mills at 5000 Katy Mills Circle hosts an indoor holiday experience most years, with seasonal scenery, ice skating, and holiday photos under one roof. The operator changes from season to season, the current format is Coca-Cola's Classic Christmas, an Alpine Adventure-style show, and prices and dates change with it. Treat the mall's official events page as the source of truth rather than any guide.

Around Cinco Ranch and further out

Closer to home, LaCenterra at Cinco Ranch runs its own tree lighting and holiday programming through late November and December, which the fall events post covers in more detail. The Katy Heritage Society typically hosts a family evening at Katy Heritage Park with historic-home tours, crafts, cocoa, and hayrides.

One honest note about this whole list: the recurring events above have held steady in recent years, but none of the 2026 dates were official when this post was written. The weekly things-to-do page tracks these events as dates get confirmed and removes them once they pass, so it stays current all season.
