Our guides draw on a mix of official and practical sources, cross-checked wherever possible:

Safety-relevant information

For anything safety-relevant — trail difficulty, avalanche terrain, technical sections, seasonal closures — we favour caution and multiple sources, and we clearly separate general guides from technical or winter/avalanche terrain. See our Weather Data page for where our forecast information comes from.

What we don't do

We don't invent distances, elevation gain, times, prices, opening hours or trail conditions, and we don't claim a route was personally walked or ridden unless it was.
