Full Route Report

The Great Ocean Walk is a 104km point-to-point coastal trekking route in Victoria, Australia.

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.

Full Scale Documentation
Route A // Hazard Verdict
GR34 — Sentier des Douaniers
MODERATE // CHLG
tide awareness: Brittany has some of the highest tidal ranges in Europe. Certain low-level path variations and beach crossings can become submerged during high tide.
atlantic weather: The exposed coastline is subject to rapid weather shifts; powerful wind and rain can make walking demanding on the more isolated points.
Route B // Hazard Verdict
Great Ocean Walk
MODERATE // CHLG
tidal beach crossings: Specific segments at Milanesia Beach and Wreck Beach are subject to tidal inundation, making passage impossible during high-tide phases.
venomous wildlife (Tiger/Copperhead snakes): The Great Otway National Park is a habitat for Tiger Snakes and Lowland Copperheads, particularly in dense scrub and sun-exposed sections.
