Glymur Waterfall

MODERATE // CHALLENGING
Full Route Report

Canyon adventure near Reykjavík. Glymur was long regarded as Iceland’s tallest waterfall (198m / 650ft) until the glacial retreat revealed Morsárfoss in 2007. Regardless, it remains one of the most scenic and technically engaging day hikes just an hour's drive from the capital. Tucked into the back of Hvalfjörður (Whale Fjord), the 7km loop hike offers a genuine sense of adventure. The route involves crossing the Botnsá river via a suspended log, navigating a natural stone cave, and ascending steep, often muddy canyon rims equipped with fixed rope handholds for stability. The reward is an aerial view into a moss-covered chasm where the massive falls plunge through a narrow slit in the volcanic rock.

Nahuel Huapi Traverse (4 Refugios)

LETHAL // NO-MARGIN
Full Route Report

The Nahuel Huapi Traverse is a multi-day hut-to-hut route that circumnavigates the mountain ranges adjacent to San Carlos de Bariloche. The trail follows a high-alpine path, connecting four distinct mountain refugios via ridgelines, loose scree slopes, and granite passes. The terrain is characterized by a mix of Andean forest and exposed high-altitude terrain, where route-finding and stability on loose rock are primary requirements. The system of stone huts (refugios) provides a logistical framework for the journey, though hikers must be prepared for sustained physical output in an exposed mountain environment.

HikeMetrics Hazard Scale — Explanation

SERIOUS // HIGH CONSEQUENCE

LETHAL // NO-MARGIN

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.

Full Scale Documentation
Route A // Hazard Verdict
Glymur Waterfall
MODERATE // CHALLENGING
steep muddy cliffs: The trail on the east side of the canyon skirts extremely close to the vertical drop. The dirt is often slick with rain and loose gravel.
the log crossing: The first river crossing requires balancing on a single log suspended over fast, freezing water while holding a wire.
Route B // Hazard Verdict
Nahuel Huapi Traverse (4 Refugios)
LETHAL // NO-MARGIN
technical scrambling and exposure: Portions of the route, particularly the section between Jakob and Laguna Negra, involve steep terrain with significant fall potential and Class 2-3 scrambling sections on loose rock.
mountain weather variables: The ridgelines are fully exposed to regional weather systems. High winds, temperature drops, and sudden precipitation can occur regardless of the season.
