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.

Grinnell Glacier Trail
EXPERT // HAZARD
grizzly bears: The Many Glacier valley has one of the highest densities of grizzly bears in the lower 48 states.
steep snow crossings: Even in mid-summer, a late-melting snowfield often covers the steep trail just before the glacier basin. A slip here can result in a serious slide down the mountain.
Route B // Hazard Verdict
Thorsborne Trail
EXPERT // HAZARD
estuarine crocodiles: Saltwater crocodiles (Crocodylus porosus) inhabit the coastal waters, estuaries, and lower creek reaches of Hinchinbrook Island.
marine stingers: Marine stingers, including Box Jellyfish and Irukandji, may be present in coastal waters, especially during warmer months.
