MODERATE // CHALLENGING
Full Route Report

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.

Tour du Cézallier (Vaches Rouges)

MODERATE // CHALLENGING
Full Route Report

Known as the 'Tour des Vaches Rouges' (Tour of the Red Cows), the Tour du Cézallier is a deep dive into France's most isolated, windswept volcanic plateau in the Auvergne volcano region. Tucked between the Cantal and Sancy mountains, this 135km loop offers an experience vastly different from the Alps—a vast, rolling ocean of high-altitude grasslands (estives), peat bogs, and glacial lakes. It is a hike defined by total silence, minimalism, and the rhythm of the wind. Note: Compiled from public sources — not a field report.

LETHAL // NO-MARGIN

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
Across the Llŷn (Wales Coast Path)
MODERATE // CHALLENGING
Cliffs and Erosion: Portions of the path follow extremely high, unstable grass-topped cliffs. Undercutting and landslides are common after heavy rain.
Weather Volatility: The peninsula is highly exposed to Atlantic swells and sudden gale-force winds that can reduce visibility to meters.
Route B // Hazard Verdict
Tour du Cézallier (Vaches Rouges)
MODERATE // CHALLENGING
navigation in dense fog: The Cézallier is notoriously exposed. Sudden, dense fogs (brouillard) can drop visibility dramatically, making the featureless grasslands disorienting.
wind chill and weather shifts: Informally nicknamed the 'Auvergne Siberia', the plateau is open to powerful westerly winds that can cause temperatures to drop rapidly even in summer.
