Source: TerraClimate 1991–2020 monthly averages. Averages for the area at each point’s elevation (4 km grid, corrected for height). Not a forecast or a report of current trail conditions. Snow at the high point is estimated with a simple snowpack model from these temperatures and precipitation, not observed; steep islands and high summits can hold more snow than it shows. Daylight is for the 15th of each month. Hut, transport and park seasons are separate: check them for your dates.

Averages cannot establish current trail conditions. Check recent local reports, the forecast and restrictions before departure. Snow and ice can persist on shaded sections or arrive outside the usual season.

Safety & Bailouts

Exit routes not verified

We do not have a verified emergency exit plan for this route. A nearby settlement, hut or route endpoint is not necessarily reachable or open. Do not leave the trail based on a straight-line distance or compass direction.

Mapped high point: 251 m, approximately 2.2 km along the route. This is not an assessment of the most remote or exposed point.

Review possible exits against current local information before your trip. In an emergency, contact local rescue services; this page is not live rescue guidance.
