Morro Dois Irmãos (Two Brothers Hill)

STANDARD // RT
Full Route 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.

Nakasendo Trail (中山道)

STANDARD // RT
Full Route Report

A walk through the Edo period. The Nakasendo (中山道) was one of the 'Gokaido' (Five Routes) of the Edo period (1603-1868), connecting Kyoto and Edo (Tokyo). While much of the route has been modernised, the 'Kiso-ji' section in the deep Kiso Valley remains beautifully preserved. Hiking between the post-towns of Magome and Tsumago follows the original stone-paved path (ishidatami) through cedar forests and over historical passes. With their dark wooden buildings and absence of cars, these towns represent a significant cultural legacy of Japan's inland history.

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.
