The Pen y Fan Horseshoe

EXPERT // HAZARD
Full Route Report

Pen y Fan is the highest peak in South Wales (886m) and the crown jewel of the Brecon Beacons National Park. While thousands stream up the 'tourist path' from the Storey Arms every day, the true mountaineer's route is the Beacons Horseshoe starting from the Neuadd Reservoir. This challenging 10-mile (16km) circular route climbs steeply onto the Craig Fan Ddu ridge, walks the long, grassy skyline over four peaks—including the 'diving board' rock at Fan y Big, Cribyn, Pen y Fan itself, and Corn Du—before descending back to the valley. It provides magnificent 360-degree views over the sheer, glaciated northern faces of the peaks down into the emerald Welsh valleys.

Prossautal — A Glacial Box Valley in Hohe Tauern

LOW // ACCESS
Full Route Report

Deep within the Hohe Tauern National Park, the Prossautal is a valley that branches off the Kötschachtal near Bad Gastein. This long but mostly flat trail follows the Kötschach Ache river into a classic glacial box valley. The rock walls on either side rise significantly, with multiple thin waterfalls cascading down the granite faces. The trail ends at the Alpengasthof Prossau, a traditional alpine inn positioned near the base of the Tischler glacier.

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
The Pen y Fan Horseshoe
EXPERT // HAZARD
steep undulations: While the main ridge looks flat on a map, the saddles (bwlchs) between the peaks drop sharply and require steep, rocky climbs back up the other side.
weather exposure: The open, grassy ridges offer absolutely zero shelter against the prevailing westerly winds and driving rain.
Route B // Hazard Verdict
Prossautal — A Glacial Box Valley in Hohe Tauern
LOW // ACCESS
length exhaustion: The 14km round trip is longer than it appears on a map, especially for families with small children.
