The Imperial Road allows for an interpretation of the historical connection between Mangaratiba and São João Marcos, associated with the coffee trade in the 19th century. The consulted source places its opening in 1857 and describes structures such as galleries, bridges, and retaining walls. Its tourism value lies in observing how engineering techniques, terrain, and economic circulation are related, without forgetting the enslaved labor and inequalities of that period. It is not an exclusively pedestrian trail: there are sections with traffic and varying conditions. Organize stops at authorized locations, avoid walking on the road bed, and check the road's condition after rain. The full route crosses areas beyond Mangaratiba. Sources consulted on 09/30/2026.
