Translated literally as 'The End of the World', this spectacular 8km loop is located in the immense limestone amphitheater of the Cirque du Sixt-Fer-à-Cheval. Surrounded by towering 2,000-meter cliffs, this is a predominantly flat, welcoming walk that traces the Giffre river to its source. It is perfect for those seeking high-alpine drama without the grueling climbs usually required to find it. Note: Compiled from public sources — not a field report.
Morro Dois Irmãos is one of Rio de Janeiro's most accessible and visually rewarding trails, linking the Vidigal community with a granite peak overlooking the South Zone. The route is defined by its social-geographic transition—starting with a local transport ride through a residential favela followed by a steep but relatively short ascent through the Atlantic Forest. Unlike the more technical and remote Pedra da Gávea, this hike is a staple for fit beginners and sunset observers, providing a definitive overview of Ipanema, Leblon, and the nearby Corcovado massif.
Head-to-Head Metric Analysis
HikeMetrics Hazard Scale — Explanation
The HikeMetrics Hazard Scale is a proprietary 5-point classification system that evaluates hiking routes across five dimensions: physical demand, technical complexity, altitude exposure, weather risk, and rescue accessibility.
Unlike generic star ratings, the Hazard Scale is calibrated against altitude profiles, elevation gain per day, and logistical isolation factors — making it the most precise route classification system available.
