Potato Sack Races or 3 Legged Race. These are some of the easiest and most classic games. Bring some sacks for racing or rope to tie people together. These are oldies but goodies!
Ball Sports. Kickball, baseball, basketball, soccer, have gear available for anyone to pick up and play a game, shoot or hit balls. Set up a game of Pickle Ball. It has become such a craze around where I live and people of all ages seem to love it.
