CROIX-DES-BOUQUETS
Many of these sites are discussed in L'Habitation Sucrière Dominguoise by Michel Philippe Lerebours (Les Editions des Presses Naitonales), and because of their easy access from Port-au-Prince and the main road, I think they're offered as part of some tours (probably also in combination with visits to local artists, especially the metalworkers in Noailles for whom Croix-des-Bouquets is known). I suspect all of these sites could be easily found by just asking for them by name. Computer reconstructions of Santo and Jumécourt are described in ISPAN's bulletin #13, and Jumécourt is the focus of #31.
