My favorite place to walk in Baton Rouge, Louisiana is the Cohn Arboretum. There are walking paths, trees and more trees, bamboo, a pond, grapevines, and lots of flowers. It is usually not busy, except when the workers are there. It is well maintained and peaceful. It is also on the way to the my No. 3 spot, so I usually catch both on the same day.
This is Baton Rouge, so remember wherever you go; your bug spray and water. However, pests have never seemed to be a problem here.
