For the little ones: peanut/candy scramble, ring toss, bean bag games, stomp the balloons, pinatas
Older ones: scavenger hunts, team games
Our two favorite team games are the egg on a spoon and clothing games. Same concept, but all ages like them. Line teams up and have an end point that the person has to get to and back.
Egg game- put egg on a spoon for each team(hardboiled, but they don't know it). Each person goes down and back and passes off the spoon annd egg.
Clothing game- get large men's button up shirts and pants and belt or suspenders. Add whatever else you want, maybe a hat or pull on boots to make a complete outfit. Have one outfit for each team. Split the teams in half putting half at one end of the playing area and the pther half at the other end. Start with the clothing at the other end from the person who goes first. The first person runs down, puts on all the clothing correctly (buttons all buttoned, zipper zipped, etc.) and then goes back to next person in line. Takes it all off and next person has to put it on correctly and then go to the other end and do the same thing. The key is to have the clothing big enough to be bothersome like the pants fall down while they're putting on a shirt. Even adults like this one.
We try to take along kick and soccer balls, a wiffle ball set, horseshoes and quoits, basketball or tennis stuff if there's a court, badmiton, tetherball etc. Anything that can be used for "free play" once oganized games are over.
We've also had crafts (Oriental Trading kits work well), face painting, coloring contests, cards for soldiers, checkers tournaments, and easy or picture bingo.
