British Columbia's biggest holiday light show is marking a decade with its most ambitious edition yet. Glow Langley, now in its 10th year, will unveil a brand-new installation called Christmas Treasures — headlined by a glowing, three-storey Crystal Palace that visitors can walk through.

The show started small, as a family-run display inside a local greenhouse, and has since grown into the largest indoor and outdoor holiday event in the province. This year's Christmas Treasures theme takes an unexpected turn: it's built around an interactive underwater adventure. Expect a giant submarine to climb aboard, the towering Crystal Palace to explore, and North Pole Access Cards that visitors can use to trigger secret light displays hidden along the route. From the top of the palace you get a bird's-eye view of the site, plus a choreographed dancing light show.

In total, more than a million lights will be strung across the indoor and outdoor spaces. And it's not just about the illumination — the event includes artisan markets to browse, festive food stalls, and live entertainment throughout.

Glow Langley runs from November 19, 2026 to January 2, 2027, with timed entry slots starting between 4 and 8 p.m. depending on the day. It takes place at 6690 216 St. in Langley, a community in Metro Vancouver about 45 minutes southeast of downtown. Tickets cost between $12 and $20 per person, with the price varying by date — weekdays will be cheaper, so if you're flexible, that's the easy saving. Booking ahead online is the way to go, and evening slots will give you the full effect of the lights after dark.

Why it matters: if you're planning a festive-season trip to Vancouver, this is the kind of add-on that turns a city break into a proper holiday outing. It works for families (the interactive card element gives kids something to do beyond looking), for couples after a Christmassy evening out, or for anyone who wants a dose of winter light without braving the cold for hours — parts of the show are indoors, a legacy of those greenhouse roots. Pair it with Vancouver's Christmas markets and you've got a solid two-day festive itinerary.

Dates for the diary: November 19, 2026 through January 2, 2027, at Glow Langley, 6690 216 St., Langley, B.C. Tickets $12–$20 online.
