Full Route Report

The GR34, also known as the Sentier des Douaniers (Customs Officers' Path), is a monumental 2,000km coastal trail tracing the entire perimeter of Brittany. One of the most iconic sections is the 120km stretch along the Pink Granite Coast (Côte de Granit Rose) in the Côtes-d'Armor. This section is famous for its bizarre pink granite formations, historic lighthouses, and the turquoise waters of the Atlantic. It is an accessible yet physically rewarding journey through some of the most unique coastal landscapes in France. Note: Compiled from public sources — not a field report.

Graukogel — Pine Forests & strenuous Ridges

EXPERT // HAZARD
Full Route Report

Standing sentinel over the Belle Époque spa town of Bad Gastein, the Graukogel is a mountain of contrasts. It is famous for its ancient 'Zirbenwald' (stone pine forest), with trees over 300 years old. While the 'Zirbenweg' near the cable car station is a gentle sensory walk, the true Graukogel experience involves the strenuous, steep ascent to the summit (2,492m) and the traverse to the Palfnersee lake. The terrain transitions from scented forest to unforgiving granite ridges and scree, offering unparalleled views of the High Tauern's 'main chain' and the Ankogel massif.

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
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
Graukogel — Pine Forests & strenuous Ridges
EXPERT // HAZARD
sustained and demanding ascent: The ascent from the middle station to the summit is very steep and continuous.
steep rocky ridge sections: The ridge path toward the Palfnersee involves navigating large granite blocks requiring careful foot placement; they can be slippery when wet.
