DRY SEASON IS REALLY THE ONLY PRACTICAL WINDOW
Cusco and Machu Picchu sit within the Andean rainy season from November through April, with January through March bringing the heaviest rain. The dry season from May through October is when the Inca Trail is open, when Machu Picchu looks its best under clear skies, and when high-altitude trekking is genuinely safe. June through August is peak — Inti Raymi draws thousands specifically to Cusco in late June, and European and North American school holidays drive the July-August surge. Book your Inca Trail permits, Machu Picchu tickets and accommodation at least three months out if you’re aiming for July or August.
APRIL AND NOVEMBER ARE THE REAL SWEET SPOT
April marks the end of the rainy season — the Sacred Valley is vivid green from the recent rains, the Inca Trail reopens after its February closure, and crowds run noticeably lighter than May onward. This is a genuine sweet spot if you want good conditions without peak-season congestion. November offers similarly quieter conditions before the heavy rains return in December.
RAINY SEASON HAS ITS OWN APPEAL
The Inca Trail closes entirely for the whole month of February for maintenance and conservation. The alternative train route to Aguas Calientes, followed by a bus up to Machu Picchu, runs year-round, and the site itself stays open throughout. Visiting in rainy season means mist and occasional rain, but also dramatically smaller crowds and genuine moments of having the terraces nearly to yourself. The site looks moodier and more cloud-wreathed during this season — a different experience, not a lesser one.
FESTIVALS AND EVENTS
Inti Raymi — Festival of the Sun (June 24): the most significant Inca festival, marking the winter solstice in the Southern Hemisphere. A dramatic re-enactment of the Inca ceremony honouring Inti, the sun god, plays out at the Sacsayhuamán fortress above Cusco with hundreds of costumed participants. One of South America’s most visually striking cultural events, and the specific reason plenty of visitors time a Cusco trip for late June. Book accommodation months ahead. Corpus Christi (June, follows the Catholic calendar): a significant festival blending indigenous Andean tradition with Spanish colonial religious practice in a way that’s genuinely unique to Cusco. Statues of saints are carried through the Plaza de Armas in procession. Semana Santa — Holy Week (April, follows Easter): elaborately celebrated across Cusco, with candlelit processions through the colonial streets on Palm Sunday and Good Friday. The Lord of the Earthquakes statue is carried through the city in a procession drawing thousands. Paucartambo Festival (July 15-18): a remote but genuinely spectacular religious festival in the village of Paucartambo, six hours from Cusco, where masked dancers perform for three days honouring the Virgin Carmen — one of the most authentic, least-touristed major festivals anywhere in Peru.
