Sandcastles! With lots of people to help this classic activity can be twice as fun... and twice as big!
The Cartwheel game! In this game you start at a certain point and do cartwheels down to the water, and see how many you can do before your head dunks under!!
The rock-find game! This game can only be played at certain beaches, ones with rocks that can fit in you hand, but won't get moved to much by the waves. Everyone gets a rock, and than you throw it into the water. Than you run into the water and have ten waves to find your rock, if you don't you get a new rock.. and a strike. After you get three strikes you can still play, but can't win. The last person to get three strikes wins. { You can play with strikes or not, there are a bunch of ways we have played, get inventive.}
The Algae-monster game! In ths game you do not want to get touched by the water, or the Algae monster will get you. Everyone starts a good distance from the water. You run to the very edge of the water and mark how far you went with a rock. Everytime the waves go out, try to move farther in. But if you get touched by the water, you have been captured bt the Algae monster, you are frozen untill someone tags you. [ You can also just play for fun and not use a rock.]
Finding Crabs! This is another activity that only works at certain beaches, ones with plenty of rocks and tide pools. We did this on vacation and named them all! We even found a huge one and named it Gargantuan. Another favorite was Petunia, a medium-sized crab found the same time as Gargatuan.
