It can be difficult to find things for kids under 5 to do while visiting the Mountains. This gem in Truckee is the solution for at least a half day for that toddler to be fully engaged with lots of other kids. This is NOT day care, an adult must be present. Trust me, you will be glad you are with your child for this adventure. It has so many features for a small and humble facility, i must give them 5 stars. Truckee should be proud of this Museum as it is worth every penny spent.
