Peru
Machu Picchu's twin, reachable only by a two-day trek, where you'll likely be alone.
The trek begins with a 1,500-metre descent into the Apurímac canyon, the path switchbacking through dry scrub and cactus until the river appears as a green thread far below. Two days later, you climb to the ruins — granite terraces emerging from jungle on a ridge so remote that fewer than two hundred people visit on any given day. At Choquequirao, solitude is not a luxury. It is the default.
Choquequirao is a late 15th-century Inca site in Peru's Cusco Region, comparable in scale to Machu Picchu but accessible only by a minimum four-day round trek. Archaeologists estimate that only 30 to 40 per cent of the complex has been cleared from jungle growth — most of it remains unexcavated. The terraces include a unique section decorated with white stone llama mosaics visible from across the canyon. The site sits at approximately 3,050 metres on a ridge above the Apurímac gorge. Where Machu Picchu receives over 5,000 daily visitors, Choquequirao rarely exceeds 200.
Solo
Choquequirao is Peru's ultimate solitude destination. Camping alone on the terraces, with no lights visible in any direction and 70 per cent of the city still hidden beneath jungle, is the closest you can get to discovering an Inca ruin yourself.
Friends
The four-day trek is a proper expedition — steep canyon descents, river crossings, and camp-fire meals cooked by arrieros. The reward is an Inca city you essentially have to yourselves, with llama mosaics that almost no one has photographed.
Trail meals of quinoa soup, avocado, and bread prepared by arrieros who know every switchback by name.
Coca tea brewed at camp as the sun drops behind the Apurímac gorge — the best altitude remedy there is.
