The Complete Guide to Cusco & the Sacred Valley — 2026 Edition
Cusco and the Sacred Valley are Peru's tourist heartland — Inca ruins, Andean landscapes, and the gateway to Machu Picchu. This guide covers everything for planning a trip that goes beyond the standard tour-bus circuit.
Overview
Cusco (3,400m) is the former Inca capital, now a UNESCO World Heritage city where Inca stone foundations support Spanish colonial churches. The Sacred Valley (the Urubamba Valley, 2,800-2,900m) stretches northwest, containing Ollantaytambo, Pisac, Moray, Maras, and Chinchero — the major archaeological sites between Cusco and Machu Picchu.
Best Time to Visit
May to September (dry season): Clear skies, cold nights, best for trekking and photography. June-August is peak tourist season — expect crowds and higher prices.
Sweet spots: May-June and September-October. Dry weather, fewer tourists, lower prices. May has the greenest landscape after the rains.
November to March (rainy season): Afternoon downpours, muddy trails, some road closures. But cheaper, less crowded, and the landscape is lush. Machu Picchu stays open year-round.
Getting There
Fly into Alejandro Velasco Astete Airport (CUZ) in Cusco. Direct flights from Lima (1 hour, LATAM/Sky/JetSmart), Arequipa, and some La Pazn cities.
From Lima: flight is best. Bus is 20-22 hours through the Andes (adventurous but exhausting — Cruz del Sur runs comfortable overnight services from PEN $80-150).
Altitude Acclimatization
This is the most important section of this guide.
Cusco sits at 3,400 meters. Most visitors experience some altitude sickness: headache, nausea, fatigue, shortness of breath. Serious cases can require medical attention.
Strategy: Spend your first 1-2 days at lower altitude in the Sacred Valley (Ollantaytambo at 2,800m or Urubamba at 2,870m). Then go up to Cusco.
Drink coca tea (mate de coca) — widely available, legal, traditional
Stay hydrated — 3+ liters of water per day
Avoid alcohol for the first 48 hours
Walk slowly. Accept that stairs will wind you
Diamox (acetazolamide) is available at Cusco pharmacies without prescription — consult your doctor

The Boleto Turistico

Altitude sickness is the biggest risk. See acclimatization section
Petty theft occurs in Cusco, especially around Plaza de Armas at night. Watch bags and pockets
Unlicensed tour touts in the plaza can be persistent. A firm "no gracias" works

The colectivo minivans drive like they're auditioning for Fast & Furious. Buckle up if seatbelts exist

A few Quechua words earn enormous goodwill in the valley. The people are Quechua first, Spanish second.
The Verdict
Cusco and the Sacred Valley deserve 5-7 days minimum (not counting Machu Picchu). Two days for acclimatization in the valley, two days for Cusco, and spare days for Humantay Lake, deeper exploration of Ollantaytambo, or a cooking class. The combination of Inca engineering, Andean landscape, and one of the world's great food cultures makes this one of South America's essential trips.
