Kepler Track

EXPERT // HAZARD
Full Route Report

The loop of the lords. The Kepler Track (60km / 37 miles) is one of the most accessible yet epic New Zealand Great Walks. Unlike the Routeburn or Milford, it is a circular loop starting and finishing near the town of Te Anau. The track was custom-built for trekking and features a spectacular 20km section of exposed alpine ridgelines that provide 360-degree views of the Fiordland wilderness. It traverses through varied landscapes including limestone bluffs, alpine tussock, and dense beech forests.

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.

Route A // Hazard Verdict
Kepler Track
EXPERT // HAZARD
alpine wind exposure: The ridge section is notorious for high winds (up to 150km/h) that can blow hikers off their feet.
sandfly invasion: Lake-shore sections (Iris Burn and Lake Manapouri) are heavy with biting sandflies.
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.
