Devil's Bridge is the largest natural sandstone arch in the Sedona area and undoubtedly one of its most popular and heavily photographed hikes. Nestled in the Coconino National Forest, the trail winds through classic Sedona scenery—agave plants, juniper trees, and towering red rock formations. The hike consists of a relatively flat walk along a sandy OHV (Off-Highway Vehicle) dirt road, followed by a short but steep climb up natural rock staircases. The climax of the hike is stepping out onto the bridge itself. While it looks demandingly thin and precarious in photos, the bridge is actually quite wide (about 5 feet) and safe to walk across for those wanting the iconic picture of themselves standing suspended over the canyon.
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.
