Pedra do Telégrafo, located in Barra de Guaratiba in the western zone of Rio de Janeiro, is a famous viewpoint at 354 metres offering sweeping vistas of beaches and the Pedra Branca Massif. Visitors can hike the trail to the summit, take creative photographs on the iconic rock ledge, and enjoy panoramic views of Marambaia Restinga, Recreio dos Bandeirantes, and Barra da Tijuca. Notably, the site gained popularity during World War II as a lookout post for enemy submarines, and today it lies within the Pedra Branca State Park, one of the largest urban forests in the world, combining history with adventure.
