Fullerton Sports Complex Playground
Balancing and climbing under a big shade cover.
Arboretum and Botanical Garden at Cal State Fullerton
An earth house your kid can walk into, then bamboo and ponds to find on an easy walk.

Walk right through old railcars and cabooses. Short and sweet, which is about the right length for a train-obsessed kid.
