Terrain Analysis
Surface & Technicality
Gradient describes steepness, not exposure, scrambling, footing or current conditions. Technical difficulty is unknown where no mapped rating is available.
Tree cover and UV
🌲 Largely under trees. Good canopy at lower elevations, so the open sections are the ones to plan for.
Canopy is inferred from elevation against a 2000 m Alpine treeline and from gradient below it, not from observed tree data — treat it as an estimate. It is a different question from the terrain shade above, which is about whether a mountain is between you and the sun at a given time.
Current Conditions
Based on 1991–2020 climate averages, the weather on La Pierre qui Tourne is usually best from April to October.

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. These values describe the whole trail's lowest and highest points. 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.
