Some ideas of items & activities to keep a toddler occupied while out camping. Keep in mind that it might not always be sunny so you'll need some items for in the dining tent or camper.
Sand Toys: Bucket, Shovel, Sifter (could also use bowl, mixing spoon, funnel, etc. from the kitchen)
Small bag of Blocks
Crayons, Paper, and Stickers
Magnifying Glass (great for checking out all nature's goodies)
Doll w/ accessories (hard plastic doll, choose items that are easily washable)
Etch a Sketch
Lots of books
Playdough (store bought or homemade - see separate posts for recipes)
Nature Collage - Bring Paper & Glue. Go for a walk and collect sticks, leaves, etc. in a sand bucket.
Pet Rocks - Bring Acrylic Paint & Brushes. Find some large smooth rocks & decorate with faces or abstract art.
Drawing in the Sand
Collecting sticks for firewood
Searching for beach treasures
Swimming, Splashing, etc.
Campground Playground (if available)
Throwing a Ball or Soccer game
Check out this website for some great games you can print off and keep in the camping supplies for rainy weather.
I printed out Dominos, Matching Game, and Bingo. There's a lot more to check out though so take a peek!
