21st birthday ideas for guys

Turning 21 is a big deal and you’ve probably been looking forward to this milestone for a long time!

There’s a TON of information out there about 21st birthday ideas for girls, but guys’ party ideas seem to be a bit harder to find.

That’s why we put together this guide for insanely fun 21st birthday ideas for guys.

Whether you want to have a wild night out or a chilled night in, we have ideas for everyone on this list.

Things To Do For Your 21st Birthday

1. Go Out To The Bars

One of the most popular ways to spend your 21st birthday is to go out to the bars with friends.

Some people choose to go out at midnight on the night before their birthday, while others will go bar hopping on the actual day of. Or you could go both nights if you’re feeling really wild!

Gather up a group of friends and go check out some of the popular bars in your area. Just make sure you take Ubers between bars or have a designated driver!

2. Brewery Tour

If you’re looking for a more low-key 21st birthday celebration that still involves drinking, head to a craft brewery and take a tour.

Most breweries either serve their own food or allow you to bring food in, so make a whole night out of it and order some dinner too.

A lot of people will decide to do breweries in the afternoon and then hit up the bars or clubs later in the night. It’s totally up to you though – it’s your day!

3. Go Clubbing

Want to take things up a notch for your 21st birthday celebration? Hit the clubs!

Clubs usually have much later closing times than the bars, so you’ll be able to dance and party pretty much all night.

Just make sure that all of your friends with you are 21+. Clubs can be very strict with IDs and you don’t want anyone to get turned away.

4. Go On A Guys Trip

How fun would it be to do a guys’ trip for your 21st birthday? A huge milestone birthday like 21 is a great excuse to get your group of friends together and head out on a fun trip.

Not sure where to go? Here are some ideas for guys trip locations:

  • Las Vegas for huge parties, casinos, and plenty of nightlife
  • Miami for beach bars, clubs, and pool parties
  • Mexico for a more affordable beach vacation
  • New York or Chicago for big city energy
  • Nashville for country bars and good weather

5. Have A Theme Party

Throwing a house party for your 21st birthday? You definitely need to have a party theme!

Theme parties are becoming really popular again thanks to social media platforms like TikTok and I’m not mad about it!

Themes make a party so much more special and memorable. We have a full list of the best 21st birthday party themes here.

6. Go To A Sports Game

One of the best 21st birthday ideas for guys is to get some friends together and go to a sports game.

The sport you go see will obviously depend on the season you’re in, your location, etc.

This would be a great daytime activity if you’re planning on hitting the bars or clubs later in the night.

7. Do A Pedal Tavern

Have you ever seen a pedal tavern before? It’s basically like a giant multi-person bicycle with a bar attached.

You’ll need a big enough group for this, but if you have enough people it’s such a fun way to spend the afternoon!

Some pedal taverns will stop off at different bars, while others will just serve you drinks while you ride.

8. Do A Whiskey Tasting

If you’re a big whiskey drinker, you definitely need to celebrate your 21st birthday with a whiskey tasting.

Head to a local distillery and taste different whiskeys and learn about the distilling process.

9. Take A Mixology Class

If you’re just turning 21, chances are you haven’t made too many fancy drinks in your life. Take a mixology class and learn how to make fancy cocktails for yourself and your friends.

You’ll learn tips and tricks from a professional bartender, and you’ll have the chance to try out some different cocktails during the class!

This would be a fun 21st birthday experience with friends or as a romantic date with your significant other.

10. Go Skydiving

Want to do something extreme for your 21st birthday? Go skydiving!

Skydiving is one of those once-in-a-lifetime activities that a lot of people will do on a milestone birthday. It’s a little bit pricey, but definitely worth it for the memories!

Make reservations at a steak house near you and find a few friends or family members to go with! It’ll definitely be a memorable way to spend your 21st birthday.

13. Go To An Arcade Bar

Some arcade bars have free games to play while you drink, and others require you to buy tokens.

21st Birthday Party Themes For Guys

21. Anything But Cups (ABC) Party

People will show up to the party drinking out of hot sauce bottles, watering cans, shoes, etc. It’s so much fun and makes for some pretty hilarious pictures.

One of my all-time favorite ideas for a party theme is classy and trashy. All of your guests have the choice to show up in super fancy clothes or super trashy outfits.

People will either be dressed to the nines or look super cheap and trashy. The contrast of the two outfit styles will be so funny!
