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.

Mount Fitz Roy (Cerro Fitz Roy)

EXPERT // HAZARD
Full Route Report

The trek to Laguna de los Tres is one of the primary day activities in Los Glaciares National Park, providing a close-perspective view of the granite massif of Mount Fitz Roy (3,405m). The route follows an out-and-back trail through mixed forest and glaciated valleys, passing the Piedras Blancas viewpoint before the final ascent. The journey is defined by a significant transition from the low-lying valley floor to the high-alpine environment of the lagoon, which sits directly below the main peaks.

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
Mount Fitz Roy (Cerro Fitz Roy)
EXPERT // HAZARD
high wind exposure: Strong winds are common in the Fitz Roy massif, particularly in the afternoon. Gusts can make the final ascent unstable in exposed conditions.
lower limb strain: The final descent is steep and rocky, which can strain knees and ankles on the return journey.
