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.

Best in October

Good no real weather drawbackMixed walkable, with one drawbackPoor a serious drawback, or out of season
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.

Ratings are planning aids from typical weather or the forecast, not statements about trail conditions. Typical weather: TerraClimate 1991–2020 at each trail's lowest and highest point, corrected for height, with the Pico do Areeiro station on the Madeira peaks. Stays and status come from each guide's dated records.
