When choosing a theme for an backyard birthday party, you need to consider who the party is for and who will be attending.

If it is a party for someone with a young family and many young families will be attending, then your theme should reflect that. You will need food, drinks, games, etc. that are appropriate for families.

If it’s for younger people, then you may want something that is less family oriented and maybe a little more fancy or exciting.

Anyway, enough talking. Let’s move on to backyard birthday party ideas for adults:

1. Carnival party


A Carnival party is the most exciting backyard party ideas for adults regardless of how old you are, there’s no denying how nostalgic and fun carnivals can be at any age. With a backyard carnival party, you can have all the expected tropes while making it for adults. For example, you can hire adult clowns to entertain guests like stand-up comedians.

There is also the wonderful element of alcohol. If you set up a backyard bar, you can mix crazy and delicious carnival drinks. To that end, remember to get all the staples like funnel cakes, candied apples, and popcorn.

Why not buy or rent a popcorn machine while you’re at it? After all, nothing tastes better than freshly popped popcorn. If you want to throw the wildest garden party theme, you should give the birthday boy or girl a popcorn cake.

Don’t forget that carnivals can also refer to Mardis grass. This type of carnival has a different atmosphere if you want to make things more adult. From dazzling beads to shots galore, the party will be so exciting that your guests won’t want to leave.

2. Luau party on  


Why travel to the Hawaiian islands when you can host a luau party in your backyard, just steps away? The atmosphere of a luau is one of dancing and celebration, but also relaxation and good cheer. As soon as you put on the traditional flower chain, the lei, there is no doubt that something special is happening here.

When inviting your guests, be sure to indicate on the invitation card that they should wear casual attire. Ideally, they can wear Hawaiian shirts or other clothing with flowers or colorful patterns. Comfortable sandals are a must.

To complete the decorations for this party theme, you can use coconuts, pineapples, totem poles, and tiki torches. Nothing is more typical of a luau than a big bonfire that you can dance around even when it’s dark.

One or more fruit plates would be great. For a change from the usual fruit, try bacon-wrapped pineapple snacks. Your guests will fall in love with the taste of this snack, which you can achieve in just one bite.

With heartfelt humor and nostalgia, this would be a wonderful way to frame the theme of the party.
