Outdoor kid birthday party ideas include a pool or beach-themed party or a party that includes state fair or field day activities. For instance, prizes can be hidden at the bottom of a kiddie pool amid balloons and children can search for the prizes as a fun party activity.
Bouncy houses, large beach balls, sprinklers and several inflatable pools can make a children's pool party more enjoyable. The party site can also be decorated with synthetic palm trees or large umbrellas if the party has a beach theme.
Field day activities that can make a party enjoyable include sack races and tug-of-war. A tug-of-war game may be more fun for older children if they stand on crates and try to keep their balance while attempting to win the game.
A wild west birthday party for a child can also be held outdoors. Activities such as a tin can shoot, where a child wins a prize when he shoots all the stacked tin cans down with a squirt gun, and pin the tail on the horse can make the party more exciting. Children can also play a game of horseshoes and enjoy birthday cake in the shape of a cowboy hat or cowboy boot.
