The pass sits at an altitude of approximately 1,669 meters above sea level.
It serves as the historical crossing point for the road connecting the Paraíba Valley to the southern mountains of Minas Gerais.
The site acts as the official access route for the 'Parte Alta' (high sector) of Itatiaia National Park.
During winter months, temperatures at the pass frequently drop to freezing levels, with occasional frost occurring on the surrounding slopes.
The road passing through the gorge, the BR-354, is known for its intense incline and sharp curves that challenge heavy vehicles.
Garganta do Registro is a high-altitude mountain pass located at an elevation of 1,669 meters in the Serra da Mantiqueira, acting as a natural geographic junction between the states of Rio de Janeiro and Minas Gerais. It serves as the primary gateway for vehicles accessing the southern entrance of the Itatiaia National Park, specifically the section leading to the Agulhas Negras massif. The site is a major transit point for mountaineers, cyclists, and off-road enthusiasts traversing the boundary between Engenheiro Passos and Itamonte. The area is characterized by dramatic mountainous terrain, rapid weather shifts, and steep, winding sections of the BR-354 highway. It functions as a climatic divide, where moisture from the Atlantic side often meets drier, cooler air from the Mantiqueira plateau. The pass remains one of the highest paved points in the Brazilian road network.
