Halloween décor just got a major upgrade. LEGOLAND® California has unveiled its first-ever LEGO® Halloween Tree — a towering creation made from nearly 681,000 bricks — and it’s as spooky as it is impressive. The one-of-a-kind display is the centerpiece of the park’s Brick-or-Treat celebration, and it’s sparking a wave of DIY inspiration for families and Halloween superfans everywhere.
Inside the park’s 680,963 brick LEGO Halloween tree
he LEGO Halloween Tree at LEGOLAND California is covered in spooky details, including a black cat, snake, and giant spider woven into a web.
Standing 17 feet tall and stretching 12 feet wide, the LEGO Halloween Tree is officially the park’s largest brick-built creation ever. It took five Master Model Builders more than 4,000 hours to complete, and the detail shows. The tree is decorated with cobwebs, ghosts, black cats, and bright orange pumpkins, all crafted from the same interlocking pieces kids (and let’s be honest, plenty of adults) have at home.
It’s not just for show. The tree actually comes alive with moving eyes and eyebrows that track guests as they walk past, paired with eerie sound effects and twinkling lights that transform the entryway into a Halloween spectacle.
What to expect at Brick-or-Treat 2025
The tree is only the start of the Brick-or-Treat fun. LEGOLAND California’s Monster Party runs on select weekends from September 20 through November 1, turning the entire park into a candy-filled, monster-themed celebration.
Think candy stations stocked with Haribo gummies, dance parties hosted by LEGO monsters, and live entertainment tailored to kids who want spooky but not scary. This year, the park is adding Lord Vampyre’s V.I.M. Costume Party, where families can compete for prizes — including a brand-new “Best Space Themed” category, timed to the park’s space-themed indoor coaster coming in 2026.
For parents planning ahead, there are deals to be had: up to $20 off advance tickets, 20% off hotel packages, and free admission for the rest of 2025 if you buy a 2026 Annual Pass.
Why Halloween trees are suddenly everywhere
Ten years ago, the idea of a “Halloween tree” might have sounded strange. Now, it’s one of the fastest-growing DIY decorating trends. Black or orange artificial trees — decorated with skulls, skeletons, bats, and pumpkins — are all over YouTube, TikTok and Pinterest in September and October.
For families, it’s a fun way to stretch the holiday season. Instead of packing away ornaments until December, people are putting up a Halloween tree first, then transforming the same setup into a Christmas tree later. LEGOLAND’s brick-built version feels like the natural evolution of the trend: a bold, playful centerpiece that goes beyond carved pumpkins and yard inflatables.
How to build your own LEGO Halloween tree
You don’t need nearly 700,000 bricks to recreate the look at home. A DIY LEGO Halloween tree can be as small as a foot tall and still grab attention. Here’s how to pull it off:
Start with the base
Every stable LEGO build needs a strong foundation. Use a wide baseplate and stack brown or black bricks upward in a pyramid or column shape. If you don’t have enough matching pieces, mix in dark green or gray for a gnarly, “haunted forest” effect. If you need LEGO’s, you can grab this Classic Brick Box on sale for 33% off on Amazon ($40, originally $60).
Shape your branches
Unlike a traditional Christmas tree, a Halloween tree can look eerie and asymmetrical. Use angled LEGO pieces, Technic beams, or even wheels to jut out branches. Don’t worry if it looks imperfect — spindly and crooked is exactly the vibe. If you don’t have enough LEGO pieces, this LEGO compatible Dark Gray 100 Piece Building Block Set sells for $15 on Amazon.
Decorate with spooky details
This is where you can really have fun. LEGO sell small kits including this adorable Halloween Cat & Mouse Building Kit ($48 on Amazon), but you can also improvise. Stack orange 1×1 bricks to mimic pumpkins, or layer white sloped pieces into ghost-like shapes. Mini-figures dressed as skeletons, vampires, or witches make great tree “ornaments.”
Add lights for a glow-up
Fairy lights are a game-changer. Wrap a short string of battery-operated LEDs around your LEGO tree for that twinkling, LEGOLAND-style glow. Purple and orange lights hit the perfect spooky sweet spot. This 20-pack of LED Fairy Lights is on sale for $13 on Amazon.
Make it interactive
Want to get closer to the real LEGOLAND tree? Add motion. You can attach LEGO eyes ($6 on Amazon) to hinges and make them blink, or buy a low-cost LEGO motor set to add simple movements. Even a wobbly pumpkin head will wow your kids.
Other ways to DIY a Halloween tree without LEGO
If your brick collection is limited, the Halloween tree trend is easy to recreate in other ways. Black mini Christmas trees ($24 on Amazon) are selling fast on Amazon and at craft stores, and they’re a perfect blank canvas for spooky décor. Swap ornaments for hanging rubber bats ($17 on Amazon), tiny pumpkins, or glow-in-the-dark skeletons. You can even spray-paint a fallen branch black, anchor it in a pot with gravel, and decorate it with cobwebs and lights.
Why it’s worth trying this year
Halloween trees tap into what people love most about the holiday: playfulness, imagination, and the chance to go over-the-top without apology. LEGOLAND’s 17-foot version might be the ultimate example, but a tabletop version at home can spark the same joy — and maybe even start a neighborhood trend.
Whether you’re visiting Carlsbad for Brick-or-Treat or just scrolling for new décor ideas, the LEGO Halloween Tree proves one thing: Halloween isn’t just about pumpkins anymore. This year, it’s about trees, too. And building one might be the most fun you’ll have all season.
