"Les randonneurs" is a comedy about a group of 5 thirtyish people (lovers or ex-lovers, as it is fashionable in the latest trend of French comedies) hiking their way in the (not so) wild Corsica to meet their own self. This is more "City slickers" than "Deliverance", though, so don't expect anything more dangerous than a hungry wild boar. It's typically the kind of movie which is held together by its actors, led by "Man bite dog"'s serial killer Benoit Poelvoorde, here the would-be charismatic leader of the group, actually a self-important, but pathetic, idiot, whose loves to explain others how to set one's left foot on the ground, and then the right one, well, how to walk. Also noticeable is Karin Viard, who is doing a great job as the temperamental whiner of the group. Of course, the movies' situations and characters are even more enjoyable if you've been on hiking trips yourself, because you're likely to recognize them.
