What you gain in May

  • 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
  • Corpus Christi (late May or June, date varies) — one of Cusco's most dramatic colonial-Andean festivals, with elaborate effigies of saints paraded through the Plaza de Armas

What you sacrifice

  • 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
