How we pick months
Best months are those where the 1981–2010 average daily high is 10–27 °C (50–81 °F), the average overnight low is 0 °C (32 °F) or warmer, and average precipitation is 200 mm (7.9 in) or less. Values are long-term monthly averages for the ~1 km cell at the trail point on the map, from CHELSA V2.1 climatologies (Karger et al., CC0), not a forecast. Higher or more exposed parts of a route can be colder, wetter or snowier.

How it’s scored
Hikers can rate difficulty from 1 to 10 (1 = flat, short, easy walk for anyone; 3 = gentle hills, a little effort; 5 = moderate climbs, some fitness needed; 7 = steep or long, solid fitness required; 10 = extremely strenuous or technical; long steep climbing; experienced hikers only). The community average is shown once at least 3 people have rated the trail; until then the official or computed score is used when we have one.
