Devil's Bridge

STANDARD // RT
Full Route Report

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.

The Gaisalmsteig — Achensee’s Fjordside Path

STANDARD // RT
Full Route Report

The Gaisalmsteig is one of the most scenic lakeside trails in the Alps, often described as 'Tyrolean Fjord walking'. Connecting the villages of Pertisau and Achenkirch along the western shore of Lake Achen (Achensee), the trail is only accessible by foot or by the Achensee boat service. The path alternates between wide forest tracks and narrow, rocky ledges that drop directly into the turquoise water. Halfway through, the Gaisalm mountain inn provides a secluded retreat with no road access, reachable only by those who hike or take the ferry.

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.

Route A // Hazard Verdict
Devil's Bridge
STANDARD // RT
crowd congestion and waiting: Due to its immense Instagram popularity, waiting in line to take a photo on the bridge can take over an hour during peak season.
heat exhaustion: Summer temperatures in Sedona frequently exceed 100°F (38°C), and there is very little shade on the trail.
Route B // Hazard Verdict
The Gaisalmsteig — Achensee’s Fjordside Path
STANDARD // RT
narrow sections head for heights: Some parts of the trail are narrow and elevated above the water, which can be challenging for those with significant vertigo.
slippery limestone steps: The rock steps can become polished and slippery, especially after rain or early morning humidity.
