Hideouts and Strongholds

Did you know that the walls of some castles are more than 12 feet thick? Or that the Great Wall of China has more than 25,000 watchtowers? Or that one of America’s most secure underground military bases is located inside a mountain, under a mile of earth and rock?

You’ve probably built forts at home from boxes or sheets, but at Camp Kinda, we’re taking that a step further. Get ready to explore a world’s worth of hideouts and strongholds, from hardened fortresses and towering castles to lonely outposts in far-off places (like outer space). You’ll learn why humans might someday live in caves on Mars, swim into an underwater research lab, see some castle-building in action, and even meet a few animals known for making hideouts of their own.

weekly family activity

Watch the animated film Howl’s Moving Castle together. This beautifully animated fairy tale from Japanese director Hayao Miyazaki features an entirely different type of castle—one that clatters around on mechanical legs and houses a dreamlike cast of characters. Check the Common Sense Media review for more information and to make sure it’s a good fit for your family.

More Adventures


When did "sports" begin? Is ironing clothes a sport? Can you play hockey under water? What if you combined soccer and volleyball? Find out in this Camp Kinda adventure, where we'll be vaulting into sports like limbo-skating, Parkour, toe-wrestling, and worm-charming, and checking out some wacky sports traditions, fans, and food along the way.



The idea of making simple materials magical by combining them in different ways has fascinated us humans for centuries. Today, people around the world still mix up magical new creations, but we use different words to describe them—words like "scientist," "chemist," or even..."chef". This week at Camp Kinda, it's your turn to let your inner mad scientist loose.
