Perito Moreno Glacier Trail

EXPERT // HAZARD
Full Route Report

Guided glacier trekking on the Perito Moreno Glacier is a specialized activity within Los Glaciares National Park. The glacier, covering approximately 250 square kilometers, is one of the few advancing ice masses in the Patagonian Andes. Access to the ice surface is strictly regulated and conducted via two primary excursion formats: the 'Minitrekking' (introductory) and the 'Big Ice' (extended exploration). Participants navigate a dynamic landscape of crevasses, moulins, and ice ridges using technical equipment under professional supervision. The experience provides a direct perspective on glacial movement and the hydrological processes of the Southern Patagonian Ice Field.

Valley of the Rocks Loop

STANDARD // RT
Full Route Report

The Valley of the Rocks is one of Exmoor's most famous and striking geological features. This very popular 3.8-mile (6km) circular walk starts in the picturesque Victorian cliff-top town of Lynton. The outward leg follows a relatively flat, fully paved section of the South West Coast Path, carved directly into the sheer cliff face high above the Bristol Channel. Upon reaching the Valley—a surreal, dry U-shaped valley littered with massive, jagged gritstone rock formations (tors) and a resident herd of feral goats—the route loops back inland via the higher ground of Hollerday Hill. It is a walk of immense, dramatic coastal views requiring very little sustained climbing.

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
Perito Moreno Glacier Trail
EXPERT // HAZARD
dynamic glacier surface: The glacier is in a state of constant motion, resulting in the shifting of ice formations, crevasses, and drainage channels.
high reflective glare: The albedo of the glacier surface results in high UV reflection, which can lead to rapid eye strain or solar retinopathy (snow blindness) without protection.
Route B // Hazard Verdict
Valley of the Rocks Loop
STANDARD // RT
the coast path drop: The paved section of the South West Coast Path from Lynton to the Valley is wide and level, but it is cut directly into a precipitous cliff edge dropping vertically hundreds of feet into the sea.
scrambling risks: Many people attempt to scramble up Castle Rock. The rock is sharp gritstone, and a fall can be serious.
