Visit Marcahuasi

Cross the last Inca rope bridge, hand-woven from grass and rebuilt by four communities every June

Set eyes on Río Abiseo, the UNESCO park almost nobody may enter — cloud-forest ruins and a monkey back from the dead

Watch the sun rise along the Thirteen Towers of Chankillo, a 2,300-year-old solar calendar in the desert

Earn the impossible turquoise of Laguna 69, a glacial lake under the white walls of the Cordillera Blanca

Hike through cloud forest to Gocta, a 771-metre double waterfall the wider world only learned of in 2005

Hike to Millpu, a staircase of a hundred turquoise travertine pools hidden in an Ayacucho gorge

Wind-carved chalk mushrooms and icebergs of rock glowing at sunset — camp overnight under the Sahara stars.

A 70-metre crater of natural gas that has burned since 1971 — camp beside the "Door to Hell" at night.
