Classic Outdoor Birthday Party Ideas For Adults
1. Fiesta
The first idea is a good ‘ole fiesta! Bring on the tacos and mariachi band! Add a pinata with something the guests might enjoy such as gifts cards or money.
2. Luau
Next, try a party luau style! Have guests come dressed in Hawaiian shirts and hula skirts.
Roast a pig and drink fruity drinks from coconuts surrounded by tiki torches. Certainly, the limbo or learning the hula would be great entertainment.

3. Western
You don’t have to live in the southwest to enjoy this Western theme. Cook a pot of chili with a side of cornbread. Then, dress in your chaps and boots in a “Wanted” photo booth. Next, try out toy pistol shooting or country dancing surrounded by Saguaro cacti.
4. Space
Another idea that is out of this world is the space theme! Astronauts, aliens, planets, and stars will all add to the ambiance. Bring the stars to you by providing a telescope for guests’ viewing pleasure.
5. Carnival
Take a turn on a carnival-themed party. Hot dogs, cotton candy, and snow cones are just a few ideas for tasty treats. Carnival games like bean bag toss, balloon darts, and a disk drop will thrill your crowd.

6. Beach
Bring the beach to your backyard! Complete with beach umbrellas and neon-colored sunglasses. Have a sandcastle building contest in your sandbox and play beer bottle ring toss! Serve beach-themed drinks such as Pina Colada, Bahama Mamma, or Sand in Your Shorts.
7. Movie Night
Do you love movies? Set up a large outdoor movie screen and show the birthday boy’s (or girl’s) favorite movie. Rent a popcorn machine to serve fresh buttered popcorn with red vines.
In addition to a projector, screen, and sound make sure to provide comfortable seating. It can be as simple as blankets and pillows on the ground. Previews optional!
8. The Eighties
Your guests will love dressing up in the puffy sleeves and big hair of the 80s. Don’t forget to have a photo booth to capture the looks. Create a dance floor in your backyard and practice your moonwalk to the best Michael Jackson beats.
9. Over The Hill
Claiming you’re vintage, left your youth behind, or old as dirt; an over hill party can be a tease! Guests can enjoy walker races, eye exams, and party treats in prescription bottles.
10. The Fifties
Vinyl records, classic cars, and jukeboxes all combine for the perfect 50s party. For example, have guests dress in poodle skirts and letterman jackets. Serve burger and fries with a coke bottle.
Then, turn on that rock n’ roll and party all night! Games may include “Name that 50s TV show”, hula hoop contest, and bubble gum bubble contest.
11. Casino
Let the Vegas Strip be your inspiration. Just like Vegas, cards, pools, dice, and anything goes at a casino party! Take a gamble by throwing a Casino party outdoors.
