Built in the 1940s as Campos do Jordão’s grandest alpine resort, Hotel Mont Blanc closed suddenly in the late 1980s after a guest was found dead in her room under unclear circumstances. Since abandonment, explorers have filmed doors slamming on the third floor, children’s laughter near the drained pool, and a shadowed woman peering from the suite once called “Apartamento 31.” Locals blame the hotel’s downfall on a fire that destroyed its chapel, and some say the bells still ring before midnight when fog rolls through the valley. Featured on Brazilian paranormal channels such as Caçadores de Lendas, it remains a magnet for ghost hunters chasing proof of the mountain’s cursed elegance.
