Across the Llŷn (Wales Coast Path)

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.

Lençóis Maranhenses National Park Trek

MODERATE // CHALLENGING
Full Route Report

Lençóis Maranhenses is a vast field of mobile sand dunes positioned along Brazil's northeastern coast. The landscape is defined by the seasonal accumulation of rainwater in the valleys between dunes, creating thousands of clear freshwater lagoons from May through August. The 43km trekking traverse between Atins and Santo Amaro involves sustained walking across soft sand slopes and navigating between the remote Baixa Grande and Queimada dos Britos oases. The primary challenge is the combination of high thermal stress, intense solar reflection from the white sand, and the physical load of soft-substrate movement.

HikeMetrics Hazard Scale — Explanation

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
Lençóis Maranhenses National Park Trek
MODERATE // CHALLENGING
severe sunburn and heat: The bright white sand reflects UV radiation from below, doubling sun exposure. There is absolutely zero shade on the dunes.
getting lost: The wind erases footprints in minutes. Every dune looks exactly the same, making navigation impossible without a guide.
