Deep in the dry tropical forest near Bagaces, Rio Perdido is arranged above a secluded thermal gorge, with elevated bungalows placed lightly among the trees. Bedrooms open towards private terraces and forest views, using dark timber, broad glazing and restrained interiors to keep attention on the reserve. Days can move between the naturally warm river, three swimming pools, canyon trails, mountain-bike routes, white-water tubing and canyoning, with the restaurant and pool bar forming the main social hub. The property’s most distinctive landscape remains below the bungalows, where mineral-rich water runs through rock pools beneath the forest canopy.
