Currently on a tent camping trip with my daughters, ages 14, 11, 9
We have
Played uno, skipbo
Hiked
Bike rides
Eaten at delicious local restaurants
Badminton
Local playground
Play in the stream
Gymnastics/yoga
Walked around campground
Other things we've done in the past:
Cave tour
Movie theater
Kayak
Fishing
For us it's about finding the right campground. We prefer a private one that has local hiking, bike trails, stream to play in. It's amazing how much my older 2 love to put the phones away and enjoy each other :)
