Distance notwithstanding, the Treehouse Museum in Ogden is the best. The best. We have a routine down for our visits there which include:

— Monday mornings: discounted admission ($3 for kids age 1-5, $1 for adults)

— Taking the pristine Frontrunner train from SLC to Ogden

— Post-museum take-out from Costa Vida on the way back to the train

— Eating lunch on the train on the return trip

— Exhausted (calm) kids after a long day

This is the kind of outing that fills your whole day when you have a day that needs to be filled. We don’t go there that often b/c it is such a huge time commitment but we’d probably go monthly if it was closer. Don’t let the distance intimidate you; it’s worth it!
