What and Where in  Louisiana... 

In general  there are  2 different regions:

the Cajun Prairie: the triangle Lake Charles - Eunice - Lafayette, with
vast meadows and flown fields  (for rice and crawfish),

               (swamp & crawfish)

and the Cajun Wetlands: between  Lafayette, Baton Rouge en Houma in the south: swamp area, partially "polders" with dikes (levee's), surrounded by vast swamps around the bayou's (rivers and creeks), belonging to the Atchafalaya basin ( = river with delta)

For Cajun fans there are several places  with interesting stuff :  

Mamou :    with the famous "Fred's Lounge", the souvereign of tante Sue , continuously conversating with the customers, alcoholics promoting by swaying her own bottle in the air!    Every saturday morning  live music, directly broadcasted on Radio KBon, by Paul Marx.

Eunice:  Eunice:  hometown of  cajunmusic, with his Hall of Fame, museum, Liberty Theater (concerten),  Marc Savoy's Centre ( music sessions on saturday morning; Marc Savoy builds and sells  accordeons), Radio KBon of Paul Marx,  .......
