1. The Great Gatsby
The Great Gatsby has a lot more to offer than just Leonardo DiCaprio in a snazzy suit. It’s also the perfect moodboard for a 1920s glam party filled with the food, fashion and music of the flapper era. This Is one of the posher 21st birthday ideas.
Serve hors d’oeuvres on fancy platters. Host a costume contest where your guests can show off their fringe wraps and cloche hats. Keep the alcohol flowing in a way that would make the Prohibition bootleggers proud.
There’s a reason why The Great Gatsby has captured imaginations worldwide, especially when it’s time to throw a party. The “roaring twenties” were a wild ride in every possible way!
2. Casino Night 21st Birthday Ideas
Casino nights are always a hit with partygoers, so if you’re looking to impress your friends with your birthday bash, consider a night filled with glittering lights and jingling slot machines.
You don’t have to spend a lot of money. In fact, it’s probably better if you save the bulk of your funds for the blackjack table. Instead of renting limos and VIP lounges, exchange your cash for chips and see if you can make them multiply by the end of the night.
Even if you don’t win a jackpot, however, you’ll still have fun with a casino-themed birthday party. Lady luck shines on those who are turning 21!
3. Barhopping
You’re finally legal to drink! While this is the most traditional of the 21st birthday ideas, it doesn’t have to be boring.
Pop some champagne to celebrate. You can also try martinis, mojitos, margaritas, mimosas and mai tais, and that’s just a single letter of the cocktail alphabet.
The best way to explore your alcoholic ABCs is with barhopping. You can make a night of the revelry by visiting different clubs and lounges to soak in the atmosphere and get a good buzz going. Some bartenders might even give you an extra shot if you mention that you’re turning the big 21. Take advantage of the occasion while you can!
4. Road Trip
There’s nothing better than winding through back roads with the windows rolled down and the wind whipping through your hair. If you’re looking for unforgettable 21st birthday ideas, consider a road trip.
The destination doesn’t matter. You can hit up major landmarks and tourist spots; you can venture off the beaten path with hole-in-the-wall diners and bizarre roadside attractions. The most important thing is that you fully celebrate the freedom and independence that comes with turning 21.
You’re about to become an adult. No one can tell you what to do. Turn right or left as you choose.
5. Board Games
Board games are a forgotten art in the world of smartphone apps and high-tech game consoles. However, they can be a fun, affordable and low-pressure way to celebrate your birthday with your closest friends.
The classics are games like Monopoly and Trivial Pursuit. The edgier stuff would be Risk, Clue, Secret Hitler or Cards Against Humanity. You can even venture back into childhood with a boozy version of Candyland!
6. Color Party
Color parties are simple. Like their name suggests, they revolve around a specific color, and the fun part is trying to keep everything in the right shades and hues.
The streamers on the walls should be the same color as the drinks in the bar. The frosting on the cake should match the chairs, balloons and tablecloths. Your guests should be wearing head-to-toe fashion in the color of your choice.
It’ll be a crazy sight, of course, but that’s the joy of it. Color parties are one of the most unique 21st birthday ideas!
7. Bonfire Party 21st Birthday Ideas
The great thing about a bonfire party is that you can host it almost anywhere. You’ll want to check your local laws, of course, just to make sure that you aren’t starting a fire in a protected area, but most cities will allow controlled blazes in a variety of locations.
Have a bonfire at the beach to enjoy the sand and surf. Have a bonfire at a campground for games, smores and ghost stories. You can even buy a portable fire pit and start a bonfire in someone’s backyard!
The possibilities are endless, so if you like the crackle and pop of a good fire, embrace your inner pyromaniac for your 21st.
8. Masquerade
If you like drama, glamor and mystery, a masquerade party is a delightful way to celebrate your birthday. This can be one of the pricier 21st birthday ideas depending on where you decide to host it.
You can rent a party room in a big mansion and tell your guests to wear masks and elaborate Victorian outfits. You can even offer prizes if they’re able to successfully conceal their identity for the evening.
The beauty of a masquerade is that anything can happen. Anyone can be anyone else. It’ll be a memorable party for sure, and that’s exactly what you want for your 21st.
9. Birthday Brunch
If you’ve never had a fancy brunch, your 21st birthday is a great time to cross it off your bucket list. You can dress up, order flowers and tea doilies, send out gold-embossed invitations and arrange for an amazing table spread that will be the envy of your Instagram followers.
You don’t even have to do the work yourself! There are all kinds of cafes and public gardens that offer “brunch packages” in picturesque settings with on-site catering. As the birthday girl, your only job will be opening presents and munching on delicate finger foods, so put on your biggest, fanciest hat and have a blast.
10. Pool Party
It’s time to do some belly flops!
Pool parties are fun at any age, but they’re especially nice when the guests are legal adults that can sip umbrella drinks and not have to worry about toddlers in the shallow end. This is the easiest of the summer 21st birthday ideas.
Don’t feel bound by the season, though. Even if you have a winter birthday, you can host a perfectly good pool party in the heated swimming pools of your local resort or community center. You might even be able to rent out the whole space for privacy.
Grab your trunks and start planning. The water is waiting for you!
11. Photoshoot
Are you feeling cute as you come closer to the big 2-1? Commemorate the day with a professional photoshoot. Amateur photographers can be hired for the same price as caterers and DJs, so you won’t have to break the bank to get high-quality pics. Some of them might even have their own studios that will save you on costs.
Another option is to rent out a loft and create your own photoshoot space. Arrange lights, cameras, curtains and props until everything is perfect for glamour shots. Set up tables with foods and gifts if you want to host your actual birthday party in the same place.
You only get one chance to document such an important birthday. Make it count!
12. Spa Day
If you’ve always dreamed of wrapping yourself in a robe and getting a foot massage while sipping on a fancy cocktail, your birthday is a great time to bring these visions to life. Spa days are wonderful ways to pamper yourself!
Another nice thing about spa days is that they can be enjoyed both solo and in groups. If you want some time to yourself, book a one-on-one session with a masseuse or acupuncturist. If you want a bonding experience with your mom, sister or BFF, arrange for a full spa weekend with all of the perks.
Call your local spa and see what kind of “special event” packages that they offer. If you play your cards right, you can ring in your 21st in the lap of luxury!
13. Cooking or Bartending Class
You don’t have to hit the clubs to celebrate your newly-legal drinking age. There are lots of events and activities that can be enjoyed with a buzz, including cooking and bartending classes.
Bartending classes are pretty straightforward. You’ll learn how to mix drinks, identify wines, shake cocktails and pour the perfect shots. Cooking classes are also a lot of fun, especially when they have an alcoholic edge; you can learn how to bake or blend with various liquors.
Consider these options if you’re looking for low-key 21st birthday party ideas. Who says that you have to get blackout drunk to have a good time?
14. Cake Swap
A cake swap is an ingenious twist for the typical birthday party. Instead of getting gifts, ask each of your guests to bring in a fun, strange or elaborate cake. Then everyone can try different cakes all night long!
For further laughs, you can award points for the biggest or craziest cakes. Maybe the winner can receive a prize. An extra-large glass of milk might be nice.
Host a cake swap at your birthday party if you’re looking for something new and different to differentiate your 21st from all of the ones that came before it. It’s a special birthday, so it deserves a special menu.
15. Prom Night
Some people had a fun prom night. Others might have missed it, or they might wish that they had a better experience. This is one of the uniquest of the 21st birthday ideas.
Why not throw your own prom for your 21st b-day?
You can rent a big ballroom and invite all of your friends. The decorations can center around whatever theme that you’d like; birthday balloons are an obvious choice, but you can also go with something unique like “Hollywood glamor” or “jungle fever.”
Fancy dress is essential. Spiked punch is optional. When you’re hosting your own prom, the choices are all yours.
16. Destination 21st Birthday Ideas
Maybe you’ve always wanted to visit Hawaii. Maybe you’ve daydreamed about seeing the oceans of Italy or the mountains of France.
You don’t have to take an expensive trip overseas to enjoy a destination celebration. Decorate your party with all of the rivers, forests, volcanoes or snowfields of your ideal vacation site, and you can arrange for exotic food and festivities that reflect its culture.
Visiting your dream destination may happen someday. You’re still young; you have plenty of time. Until then, just go with an awesome themed party.
17. Booze Cruise
This one will require a bit of planning, but if you’re looking for a fun, unique way to ring in your birthday, consider a booze cruise. You can turn up the music and knock back the beer while enjoying beautiful ocean views with all of your favorite people.
Do you live in a landlocked area? Take a day trip to the nearest lake. Are all of the cruises booked? Rent your own boat and pack your own cooler.
At the end of the day, the practicalities of your party aren’t nearly as important as its overall vibe. As long as you have good company and good liquor while you’re on the water, you’ll have a good time.
18. Murder Mystery
Who killed the birthday girl or birthday boy? Let your guests solve your murder.
It’s actually easier than you might think to set up a murder mystery party. While it’s true that there are a lot of details involved in such an elaborate charade, you can order downloadable kits or coordinate with special event groups in your city to handle most of the grunt work.
How many people can say that they were murdered on their 21st birthday? Host a murder mystery party and make it happen. When it comes to 21st birthday ideas, harmless crime can definitely be on the menu.
19. Sleepover
You might be turning 21, but you don’t have to surrender to a boring life of adult responsibilities just yet. There’s still time for you to enjoy a good old-fashioned sleepover!
Ask your girlfriends to pack their softest, fluffiest pajamas. Gather a bunch of movies and snacks. Break out your mud masks and nail polishes. Get giggly. Play truth or dare. Dine on gourmet chocolates and gossip about your friends as you curl each other’s bangs and drink wine straight from the bottle.
You’re an adult now. You get to decide what a fun sleepover looks like, and if that includes a few nips, no one gets to judge you.
20. Football Frenzy
Fellas, this one is for you. If you’re unmoved by the thought of sleepovers and spa trips, arrange for a “guy’s night” where the pigskin reigns supreme.
You’ll have lots of options for a football-themed party. If you want to keep things simple, set out nacho platters in front of the couch and shout at the TV with your friends. If you’d like something a little more memorable for such an important birthday, rent out a local bar or arrange for a tour of your city’s stadium.
No matter what you decide, you’ll have a lot of fun bringing your favorite passion into your birthday celebration with a football-themed party.
21. Food Truck
If you don’t want to spend a lot of money on a birthday party, renting a food truck will offer a good time to your guests without putting a strain on your wallet as the host. The truck itself will be your biggest expense, and after that, it’s just a matter of bringing in some chairs to sit in and some speakers to blast your favorite music as you eat, drink, dance and socialize.
It won’t be the biggest party that your neighborhood has ever seen, but not everyone wants wild and crazy 21st birthday party ideas. Sometimes, a platter of ribs and a good playlist will do just fine!
