Which trail suits your trip? Pick a month for typical weather, or your own dates for the forecast, rated at each trail's lowest and highest point. The best match comes first; the table below has the details. For winter trips, start with hiking in Europe in winter.

How the ratings work
Good
Typical weather suits walking: no snow expected at the high point, not hot low down or cold up high, and under 200 mm of rain in the month.
Mixed
One drawback in a typical year: snow or ice possible up high, a warm or cool month, or a wet one (200 mm or more).
Poor
Snow likely at the high point, heat of 33 °C or more low down, days below 3 °C up high, or outside the published season.

From typical weather: the 1991–2020 averages at the trail's lowest and highest point, corrected for height. A published season (a park that closes, huts that open) overrides the weather. A rating is a planning aid for the area, not a report of the trail: check the official warnings before you go.
