Seasons and Climate
The ideal time of year to hike the Inca Trail is from May-September (the dry season). April-October, the months during which the seasons are changing, are often good for hiking. Summer months (November-April) in the Southern Hemisphere are often rainy, making access difficult and camping unpleasant. Guides usually recommend the previous days to a new lunar cycle for the hike, when the climate is stable and rain scarce.
Before embarking on the adventure by Caminos del Inca is necessary to know certain details needed to enjoy the walk correctly.
