These ideas came from scrolling through hundreds of pins and photos, then narrowing things down to the ones that actually look good in a parking lot, not just on a perfectly styled porch.
Everything here uses things you can find at the dollar store, the craft aisle or already sitting in your garage. No theme requires a truck full of props or a second mortgage, lol!
Some of these are simple enough to pull off solo in an afternoon. Others are bigger group projects if your neighbors or coworkers want to team up on a car each.
Either way, pick whatever makes you the most excited to decorate, because that enthusiasm always shows up in the final trunk.
TRUNK OR TREAT THEMES
Under The Sea Trunk Display
Blue streamers, a few pool noodles and some plastic fish turn any trunk into an ocean floor in about an hour.
Add a fishing net draped over the bumper and battery lights tucked inside for that underwater glow. This is one of those these that photographs beautifully even in daylight.
Skip the real water, obviously. A shower curtain as the backdrop does all the work without the mess.
Candy Land Trunk Theme
Everything here is oversized and sugary looking, which is honestly the whole appeal.
Giant lollipops made from foam boards, a gumdrop path taped to the ground and candy cane fence posts flanking the trunk. Kids stop walking the second they spot it.
Pastel colors work better here than bright primary ones. It reads more like a candy shop than a birthday party.
Haunted Graveyard Trunk Setup
Foam tombstones from the dollar store, some fake spiderweb and a fog machine if you own one already.
This setup leans spooky without being genuinely scary, which matters when little trick-or-treaters are involved. Nobody wants a crying toddler at their trunk.
A skeleton propped in the driver’s seat gets a laugh every single time, haha!

Black fabric or a painted sheet as the backdrop, glow in the dark stars stuck all over it. Suddenly you’re parked in outer space.
String lights doubling as planets is a cheap trick that reads surprisingly well from a distance. Silver streamers hanging from the trunk lid add movement too.

Plastic dinosaur toys scaled up with painted foam rocks make a decent Jurassic scene without a real budget.
Green tinsel curtains as jungle foliage hide the trunk opening nicely and give kids something to push through.
Roar at a few passing kids for effect. It never gets old, lol!

Red and white striped fabric forms a mini circus tent right over the trunk lid. It instantly reads as festive.
Popcorn boxes as candy holders and a ringmaster hat complete the costume side of things.
This is one of those these that works even if you only have an hour to set up.
Superhero Squad Trunk Setup
Bright primary colors, comic book style burst shapes cut from poster board and a few capes hanging from the trunk lid.

Moss fabric draped over the bumper hides the car underneath almost entirely.

This is the theme for anyone who wants maximum spooky with minimum setup time.
Ten minutes with a staple tool and you’re basically done.
Witch Cauldron Trunk Display
A big black cauldron, some dry ice for the bubbling effect and a witch hat balanced on the trunk lid.

This theme skews a little older, so keep it toward the tamer end if younger kids are around.
Tropical Luau Trunk Theme
Tiki torches, fake palm leaves and a lei draped over the rearview mirror bring beach energy to a chilly October night.
This is a nice curveball if everyone around you is doing spooky. It stands out precisely because it doesn’t match.

Last but definitely not least, we have this movie night theme. A projector screen made from a white sheet, popcorn buckets and folding chairs set up beside the trunk.
String lights hung similar to a marquee sign finish the full look.
Simple, welcoming and honestly one I’d copy first if I were starting from scratch, haha!
