Kids get bored, playing games help kids have fun in a somewhat controlled environment. Always have adult supervision when young kids are in the water.
F.I.S.H ~ F.I.S.H is like P.I.G. in basketball. The first player performs atask and the other players must replicate that task. If they can’t, they take the first letter in the word. First one to spell F.I.S.H loses.
Follow the Swimmer ~ Super fun for kids, this is a game where the “followers” must copy the leader exactly. If they don’t, they get picked off. Pick a “watcher” to eliminate the kids who don’t follow the leader exactly.
Scavenger Hunt ~ Bury pairs of items on the beach. Use items like 2 diving sticks, 2 coins, 2 pool noodles, 2 pool rings, etc.) Have teams try to collect one of each item. First team to collect one of each wins.
Canon Ball/Belly Flop ~ Have kids jump Canon Ball style or Belly Flop style and see who can make the biggest splash.
Hula Hoop Relay ~ Divide group into two teams. Each team join hands to form a circle, teams should be standing in the lake at knee level. Loop a hula hoop over one player’s arm. Without letting go of the other player’s hands, he must step into and through the hoop so it rests on his other arm. Then he can slide it onto the next player’s arm and she must repeat the same maneuver. You will need one hula hoop for each team. Whichever team can pass the hoop all the way around the circle first, without letting go of each others’ hands, is the winner.
