A lot of hotels require you to be 18+ to make a reservation. Celebrate your 18th birthday by booking a hotel room with a bunch of friends!

You could do this in your city and have a little staycation OR you could go to a nearby area and do a friend trip.

Order room service, do some face masks, and watch a fun movie on the hotel TV. Make sure to book a hotel with a pool so you can have a pool party with your friends!

2. Go To A Concert Or Music Festival

How fun would it be to go to a concert with all of your friends for your 18th birthday party?

Check to see if there are any upcoming shows in your area and get a group of friends to go with you.

If your birthday is in the summer, you could do a music festival instead! That way you can see a bunch of different performers with just one ticket.

3. Have A Picnic

Set up a table or cute picnic blanket, get some colorful pillows, and throw together a charcuterie board for you and your besties.

If you don’t want to do it yourself, there are tons of companies now that will set up your picnic space for you.

4. Host A Dinner Party

You’re a *grown up* now, so have some fun with your friends and throw a sophisticated dinner party.

Go all out with the table decorations, fancy food, and some fun mocktails.

If you’d rather not host everyone at your place, you could also rent out a room at a nice restaurant to have a private dinner party.

5. Do A Spa Day

This is definitely one of my absolute favorite 18th birthday ideas because it’s so relaxing!

You could grab a friend or two and head to the spa for a day of pampering. I love checking Groupon for good deals on spa treatments.

Or you could grab some face masks, nail polish, and body scrubs and do an at-home spa day.

6. Go For A Hike

If you have any good nature areas nearby, grab some friends and go for a birthday hike. I love this idea because you get some fresh air and exercise while still celebrating turning 18.

Make sure to head out for a good meal after you’re done hiking – you’ve earned it!

If you want to extend this 18th birthday idea you could turn it into a camping trip!

7. Throw A Theme Party

Everyone loves a good house party to celebrate their birthday. And what makes a house party even more fun? A theme of course!

Some fun theme ideas for an 18th birthday party are:

8. Have A Bonfire

Do you have a nice backyard area where you could light a bonfire? Have some friends over at night to sit around the fire and hang out!

If any local beaches allow for fires in your area, a beach bonfire is also a SUPER fun 18th birthday party idea.

9. Have An Outdoor Movie Night

Set up a white sheet in front of a wall and put a movie on over your projector. Everyone can sit in yard chairs or on blankets and pillows on the ground.

This is so much fun to do outside during the summer, but you can also do an indoor movie night if you turn 18 while it’s still cold out.

10. Do “Adult” Things

Now that you’re an adult, it’s time to do some grownup things!

There are lots of things that you can’t do until you’re 18 so now’s the time to do them. Book a hotel room, get a tattoo, visit an adult store, register to vote, etc.

Not sure what adult things you can do now that you’re 18? This article tells you everything you can finally do when you turn 18!

11. Have A Photoshoot

A great way to celebrate your 18th birthday is to have a fun birthday-themed photoshoot with some friends.

You can either hire a professional photographer for a few hours, or get a friend or family member to take some pictures of you!

Find a pretty spot outside or set up a backdrop indoors for some bomb pictures. Bonus points if you get numbered balloons to take photos with!

12. Go On A Shopping Spree

It’s your birthday – time to treat yourself! Head to the mall and have the ultimate splurge day to celebrate your big day.

This would be a fun activity to do with friends or with a family member.

Want to make your day even more special? Make sure you schedule some time for a mani pedi and some lunch while you’re out shopping.

13. Go Out For Brunch

If you’re looking for something a little bit more low-key to do for your 18th birthday, I recommend grabbing some friends and going out for brunch!

I love brunch because it feels a little bit fancier than other meals. Tell your friends to dress cute and look up the best brunch spot in your city.

14. Go To A Theme Park

How fun would it be to get all of your friends to go to a theme park with you for your 18th birthday party?

If you have a Disney theme park, Six Flags, etc. near you, you definitely need to do this 18th birthday idea.

Ride all of the rides, eat the crazy theme park food, and take plenty of pictures!

15. Rent A Boat

I live near a lake and a TON of my friends and family have access to a boat so this could be a super affordable birthday idea.

If you don’t have access to a boat, you can check online if there are any boat rentals near you.

Stock the boat up with plenty of snacks, drinks, and a good speaker so you can have a dance party. Just make sure that someone has their boating license and can drive you around!

16. Have A Pool Party

One of the most fun 18th birthday ideas for the summertime is to have a pool party.

If none of your friends have a pool at home, you can try to find a hotel or local pool that allows for party rentals.

Get plenty of pool floats, sunscreen, snacks, and drinks and invite all of your closest friends.
