Pedra do Telégrafo, located in Barra de Guaratiba, is a rock formation famous for an optical illusion that makes visitors appear to be hanging over a precipice. The location serves as the starting point for the Trilhas da Pedra Branca State Park trails. It sits at an elevation of approximately 354 meters above sea level. The primary trail begins near the entrance of the Grumari sector. The vantage point provides panoramic views of Restinga da Marambaia, Guaratiba, and the surrounding beaches. It was historically used as a strategic observation point for the military during World War II. The hike to the summit typically takes between 45 and 60 minutes depending on the pace.
