The Île aux Lépreux visit is retained because the official heritage page confirms a free guided visit by Arnauld Heuret during the Journées Européennes du Patrimoine. The source describes the former leprosarium of the penal colony on an islet in the Maroni, with departure by pirogue in front of the tourist office and limited places by time slot. This is a strong regional heritage entry because it connects river geography, penal archives and the memory of an isolated medical site, making the Maroni itself part of the interpretation of place.
