A full week in Cusco covers the whole spread: proper acclimatization, the Sacred Valley, Machu Picchu, a high-altitude day trip, the quieter South Valley, and a slower final day before you fly out. Cusco sits at roughly 3,400 meters, so this plan is sequenced to build altitude tolerance before pushing higher or descending toward Machu Picchu. Day 1 Fly into Alejandro Velasco Astete Airport (CUZ), check in, and keep the day genuinely easy.

Six days gives you room to do Cusco properly: a full acclimatization stretch, the Sacred Valley, Machu Picchu, a high-altitude day trip, and the quieter South Valley sites that most short trips skip. Sequencing matters here - Cusco sits at roughly 3,400 meters, so this plan builds altitude tolerance before pushing higher or descending toward Machu Picchu. Day 1 Arrive and keep it slow. Altitude sickness (soroche) is common in the first day or two, so rest, drink water, and skip alcohol; coca tea is a legal local remedy many travelers use, though time and pacing matter more.

Five days lets you add a genuine extra to the standard Cusco-plus-Machu-Picchu trip: a high-altitude day trip once you’re properly acclimatized. This plan keeps the sequencing that matters here - build up altitude tolerance in Cusco (roughly 3,400 meters) before either descending to Machu Picchu (around 2,430 meters) or pushing higher toward Humantay Lake or Rainbow Mountain. Day 1 Land, check in, and keep the day genuinely light. Altitude sickness (soroche) is common on arrival, so rest, drink water, and hold off on alcohol; coca tea is a legal, widely available local remedy, though acclimatization is mostly a matter of time.

Four days is the sweet spot for a first Cusco trip: enough time to acclimatize properly, see the city and a Sacred Valley day, and still fit in Machu Picchu without rushing. The key is sequencing - Cusco sits at roughly 3,400 meters, and Machu Picchu, at around 2,430 meters, is actually lower, so this plan builds altitude tolerance before you descend toward the ruins. Day 1 Keep today deliberately slow.

Three days gives you a comfortable pace in Cusco: two days to settle into the altitude and see the historic capital properly, then a full day out in the Sacred Valley. This plan is built for first-timers, with the harder walking and the higher-altitude sites held off until you’ve had a chance to adjust. Day 1 Cusco sits at around 3,400 meters, and altitude sickness (soroche) is common in the first 24 hours, so keep today deliberately easy.

Two days is enough to get a real feel for Cusco, the former Inca capital sitting at roughly 3,400 meters, but only if you respect the altitude on day one. This plan keeps the first day genuinely slow and saves the more active sightseeing for day two, once you’ve had a chance to adjust. Day 1 Take the morning easy after you land. Check into your hotel, drink water, and skip anything strenuous; altitude sickness (soroche) is common on arrival, and pushing hard on day one is the most common way to feel awful for the rest of the trip.

Cusco Travel Guide 2026: What to Know Cusco was the historic capital of the Inca Empire, and Quechua speakers still call it Qosqo, “navel of the world.” It’s also a UNESCO World Heritage city (since 1983), and the main gateway to Machu Picchu and the Sacred Valley. Walk the old center and you’ll see the pattern everywhere: precision-cut Inca stone foundations with Spanish colonial buildings stacked directly on top. This is not Lima, Peru’s modern capital on the coast; Cusco is the Andean, Inca-history side of the country.
