Mario Golf: Toadstool Tour

Are you talking about after the Bowser Badlands? If so, then there are no courses after that one, unless you consider the Congo Canopy, which is only available in the side games. (note, I'm not sure if there's a way to unlock the Congo Canopy for tournament play... I recall doing it once, but maybe my memory is faulty.)

Note, that there is the star tournament that you can get after you beat the bowser badlands, in which you can play the courses again with harder greens and players that have better scores, but there are no more courses after the Bowser Badlands.
