Where to go in August

  • The Amazon: Best wildlife watching around lakes and rivers.
  • Lake Titicaca and Colca: Clear skies and condors.
  • Treks: Dry, but book well ahead.

What to avoid in August

  • Underpacking: nights at Puno and on treks can fall well below freezing.

Festivals and events in August

  • Pachamama offerings (1 August): Andean communities make offerings to Mother Earth.
  • Santa Rosa de Lima (30 August): A national holiday honouring Lima's patron saint.
