We go to a lot of parks. State parks, metro parks, kids parks. Feed ducks go biking, hiking, collect cool rocks to paint.
My boys are 12,13 yo. my daughters are 11 yo and 7 months. We go fishing, zoo, to museums (my library offers free passes that you "check out" with your library card)
Take lots of pictures my kids love to take pictures.
We swim a lot to we go to a lot of beaches (here in MI. there are a lot to choose from that are close by)
We will also be going to Kentucky and maybe Georgia to see the In laws.
Have fun exploring. Oh yeah make up treasure hunts those are a blast.
