Best match

The dry season arrives — clear skies, the Inca Trail fully open, and Machu Picchu at its most reliably beautiful.

  • ↑Dry season proper begins: 44mm of rain is minimal, skies are consistently clear, and the mountain views from Machu Picchu and the Sacred Valley are sharp and unobscured
  • ↑Inca Trail permits are still available in May (unlike the July–August peak when they sell out months ahead) — the optimal window for hiking with full conditions and manageable crowds

Inti Raymi on June 24 — the Festival of the Sun at Sacsayhuamán is one of South America's greatest spectacles.

May trade-offs

  • ↓Nights are cold (4°C) and can catch visitors off guard; altitude at 3,400m intensifies the chill — warm layers are non-negotiable
  • ↓Prices begin rising as the dry season is recognised; May is still moderate but more expensive than the wet-season months
  • ↓Inca Trail permits for the popular Classic Trail sell out in advance — book at least two to three months ahead for May departures

June trade-offs

  • ↓The most expensive month of the year: hotel prices for Inti Raymi week can be 3–4× the low-season rate; book accommodation six months ahead or more for any property near the centre
  • ↓Inca Trail permits for June sell out up to six months in advance — this is not a last-minute destination for hikers; plan and book as far ahead as possible
  • ↓Nights drop to 2°C — the driest and sunniest conditions come with the coldest nights of the year; sleeping at altitude in winter requires preparation
