Tips for Planning the Perfect Halloween Party
Make the guest list
The first thing you want to do when it comes to party planning is to know how many people you want to invite.
From there, you can then decide on the rest – planning a small gathering with only a couple of people is not the same as planning a party that dozens of people will attend.
Pick a date and time
Check whether Halloween falls on a weekend or not, and set the date accordingly, you can also ask what’s more convenient for people you’re going to invite.
For a truly spooky Halloween party, starting it when it starts to get dark might be a good idea.
Choose the location
There are plenty of outdoor options to have a party at. It can be your garden if you have enough space, at a park, at a venue (make sure to book it well ahead, especially if your party is on the 31ft), or at someone’s else place.
Pick a theme
Once you’ve set the date and location of your Halloween party, pick out your theme! Check out some of the fun and spooky options listed below if you need some inspiration.
Now it’s time to send out the invitations. You can use Canva to make them, they have tons of templates that are pretty easy to customize. Make sure to add all useful information and if guests should bring something or not, a special dress code, anything needed for the activities you’re planning…
Get everything you need for the Halloween decorations
Whether you’re buying everything or spending some time on Halloween crafts making your own DIY decor, buy everything you need ahead as stores often run out the closer you get to Halloween.
Put together your menu
It’s not a party unless there’s food and drinks! Whether you’re hiring a caterer, asking guests to bring things, or making everything yourself, it’s best to have food and drink ideas planned out so you can plan accordingly.
A buffet is great for an outdoor party, with plenty of finger food, Halloween treats, and spooky dishes. See below for some Halloween food and drink ideas.
Plan activities and games
There are plenty of fun Halloween party games and activities for adults to keep everyone entertained. Chances are, you’ll need stuff for what you plan to do, so make sure once again you get everything ahead.
Have a plan B in case it rains
It’s hard to plan weather and as your party will be outdoors, make sure to have a plan B in case the weather turns. Maybe rent some party tents just in case, or plan to bring the party inside.
Outdoor Halloween Party Ideas and Themes
There are plenty of themes you can pick for your adult Halloween party. Below are some ideas to get inspiration from – alternatively, if you have a favorite movie you can base your party on that – movies like Harry Potter, Twilight, The Nightmare Before Christmas… are great Haloween party themes!
Murder Mystery Dinner Party
Adults will love participating in a murder mystery party, and it’s right on theme for Halloween. Turn your guests into detectives and provide them with clues to find who the culprit is.

Spooky Scavenger Hunt
Who said adults couldn’t enjoy a good scavenger hunt too? Hide Halloween-themed things outside and include goodies adults will love like booze or treats as prizes. Instead of telling everyone what they need to find, you can use riddles to make it harder.

Horror Movie Night
If you are a horror movie fan, then Halloween is the perfect occasion for a horror movie marathon. Set up an outdoor theater with a projector, pillows, blankets, and comfy chairs.
