Across the Llŷn (Wales Coast Path)
The Llŷn Peninsula Coastal Path is a remote, culturally distinct segment of the 1,400km Wales Coast Path. Stretching from the historic walled city of Caernarfon to the edge of Snowdonia at Porthmadog, the route circumnavigates a landscape where the Welsh language and maritime history remain deeply ingrained. The terrain transitions from the volcanic peaks of 'The Rivals' (Yr Eifl) and rugged granite cliffs to expansive, secluded sandy bays like Whistling Sands (Porth Oer). This is the sunniest corner of Wales, offering constant views of the Irish Sea and the sacred Bardsey Island (Ynys Enlli), the 'Isle of 20,000 Saints,' which marks the literal and spiritual apex of the journey.
GR34 — Sentier des Douaniers
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.
Head-to-Head Metric Analysis
HikeMetrics Hazard Scale — Explanation
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.
