In the United States, the 21st birthday is a milestone birthday because it's the age when you can legally drink. In other countries, the 21st birthday isn't as exciting because you might have a legal drinking age of 16 or 18, depending on where you're from. The 21st birthday is cause for a birthday celebration in the U.S. You can go to local bars, wineries, breweries, make drinks at home, or purchase your first drink at the liquor store. There are heaps of options. 

When I turned 21 I took my ID to the bar at midnight and got a drink before they closed at 2 a.m. It's a rite of passage. I didn't party all night since it was a school night and I has class the next morning, but I went out with a close friend and my roommate. They were already 21, so it was good to go out with people who already knew what they were doing. This can be a pickle if your friends aren't 21 yet and you want to go out but they are not able to. 

Whether you want to have a pool party, scavenger hunt, spa day, or take a pole dancing class, I've included a bunch of ideas on this list so that you can have a fun time no matter what age everyone else is.
