Fun Activities to do Before Summer Ends

I recently read an article about Activities to do with your children before summer ends and it gave me an idea to start my own list. I thought I would share it here for anyone else that might need some ideas of things to do as the summer draws to a close.

1. Camp out in the backyard. My children love this. Especially when Dad joins in on the fun.
2. Go to a river and skip rocks. We used to do this as kids and would see who could get the most skips.
3. Roast Marshmallows and make s'mores. We like to do this on the BBQ. They don't taste quite the same, but it works great when we aren't camping.
4. Pick a bouquet of wild flowers. My daughter thinks that wildflowers are the best and is always finding beautiful ones for me.
5. Go Swimming. We love to do this as a family. It always makes my kid's day.
6. Get up early and watch the sunrise. Our world is beautiful and kids love to enjoy the colors of a sunrise.
7. Stay up late and tell campfire stories or sing songs around a campfire. We recently sang song around a campfire and my daughter had an endless list of songs she wanted to sing.
8. Go on a hike and see how many different bugs, animals, and plants you can find. Check out a book from your local library that shows plant and animal pictures to help you.
9. Jump in the puddles with your kids on a rainy day. Children love to make messes and it is fun to be a kid again. We don't get many rainy days in Idaho, but it would give us something to do on those occasional days.
10. Run through the sprinklers. My kids love to do this on a hot day and they love it even more if I join in.
I know a lot of these entail water, but we love water. Does anyone have any ideas that I haven't listed here? Please share. We are always looking for something new to try.
