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.

Zhangjiajie National Forest Park

STANDARD // RT
Full Route Report

Zhangjiajie National Forest Park is a surreal landscape widely associated with and often cited as the inspiration for the floating 'Hallelujah Mountains' in the movie Avatar. The park is defined by over 3,000 towering, incredibly narrow quartz-sandstone pillars, many rising over 200 meters, cloaked in dense, sub-tropical jungle and frequently shrouded in mist. Hiking here involves navigating a massive, highly developed geological park. The hiking paths are heavily engineered—consisting of thousands of paved stone stairs, cliff-side walkways (including glass skywalks on Tianmen Mountain nearby), and massive outdoor elevators (like the 326m-tall Bailong Elevator).

EXPERT // HAZARD
5
EXTREME // LETHAL

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.
