Creative and Unique

1. Crafts Night

Crafting can be a fun activity for everybody involved, and it can involve many different activities, including pottery, sewing, making cards, and painting.

You can host it with a group of family and friends at your house, or head over to a pottery or art studio for the real deal.

2. Bake-a-Cake Party

It’s not a party without cake, and to save money and have fun, why not make one yourself?

You can all bake together and decorate cakes how you like them. Then the best part? Eat every piece of your cake you’ve made!

3. Treasure Hunt Party

A treasure hunt party allows you to get a little creative with planning because it’s an activity as well as a celebration.

You can plan lots of different hunts around the party, and all the decorations can be themed with the idea too.

4. Bonfire Night Celebrations

To experience the night sky and a more laidback atmosphere for your 20th birthday, a bonfire night is a way to light your birthday in a fun and unique way.

Find somewhere you’re able to set up a bonfire, launch fireworks, and bring a load of food to cook on the fire to have a great time with your friends.

5. Make your own Mocktails Night

Mocktails can be the most delicious of drinks, and the best way to experience them is by experimenting with your own.

To celebrate the big 20, invite your friends over and have everyone think of a different drink to create. The fun part? Trying them all out and seeing which is the most refreshing.


6. Glamping Holiday

Glamping is the new camping, and if the outdoor nature scene is for you, then this is the activity to consider.

Either rent out a cabin, yurt, or any type of glamping accommodation for you and a group of friends. You can have a BBQ, spend the night in a hot tub, or plan an outdoor dinner party with views of the forest.

7. Beach BBQ or Picnic

The beach is always a place for celebration, as there’s nothing more magical than watching the sun behind the sea and the sands.

For your birthday, having a BBQ or picnic here is an exciting way to gather your friends, eat some great food, and appreciate the coastline.

8. Road Trip

Nothing says birthday like a big adventure, and that’s why a road trip is always a good idea.

You can either stay local or set off afar; it’s your birthday after all. We’d suggest mapping out a route of places you’d like to see throughout the day and go have fun.

From massages, facials to getting your nails done, you’ll be completely pampered by the end of it.

10. Escape Room

For a slightly more quirky activity, an escape room should be top of your list. It’s an opportunity to do something fun with all your friends with a combination of adventure and mystery.

Each escape room has a different theme and puzzle, so you’ll always be left wanting more.

Classy and Luxurious

11. Pool Party

In the summer months, pool parties are a winner, especially if you already have a pool in your backyard.

If you don’t, there are many large pools you can hire or treat yourself to a hot tub and turn it more into a hot tub party. Wear your favorite bathing suit, switch on the fairy lights and music, and make it a night you’ll never forget.

12. Go on Vacation

Turning 20 deserves a big celebration. As it’s the start of your twenties, why not jet off somewhere new to see in this milestone?

It could be the next state over, or on a beach vacation near you, whatever tickles your fancy.

13. Trip to the Theater

Seeing a musical or show on stage is always an incredible experience and one that fills your soul with joy, meaning it is a brilliant birthday plan.

Whether you’d like to see Wicked, Hamilton, or head to your local theater, there are so many shows to go watch.

14. Designer Shopping Spree

We all deserve a little splurge once in a while, especially on our birthday, so why not hit up the designer shops for a spree? Treat yourself to a handbag, pair of shoes, or just have a browse – it’s your day after all!

15. Go to a Concert

Music is the way to our heart, and singing along to your top band or artist is an incredible way to celebrate your birthday. See what’s on in your local concert venue, or head off further afield and make a weekend of it.

Low-Key and Simple

16. Party Picnic

Picnics are one of the simplest things you can do, but they can also mean so much because you can dress them up as much as possible or have them as small as you like.

Whether it’s a simple picnic in the park or one with fancy cakes and over-the-top decorations, it can be the day you’ve always wanted.

18. Al-Fresco Dinner Party

Dining al-fresco is always better than indoors with a different dining experience and, in the warmer months, the promise of sunshine.

25. BBQ Party

BBQs are a dreamy occasion in the summer months, and even better to have for your 20th birthday.

Light up the BBQ with your favorite meat and non-meat options, and fill your garden with all types of happy birthday banners and a balloon arch.

Themed Parties

26. Great Gatsby Theme

Enter your roaring 20s with a bang and in the best way possible with a Great Gatsby theme. The roaring 20s was one of the most exciting eras in American history.

You can hire live music for the ultimate experience or have the DJ playing the best live music sets.

28. 2000s Party

Every decade is celebrated and remembered for certain events, trends, music, and fashion, and the 2000s are no different.

You can ask guests to dress up as their favorite icon from the 2000s or to be in line with what was trendy at the time.
