Cusco Travel Guide 2026: Everything You Need to Know

Planning a trip to Cusco? This guide covers everything you need to know — from altitude acclimatization and the best time to visit, to Inca Trail permits, top day tours, and hidden gems that most travelers miss. Written by the local team at Aremika Expeditions, based in Cusco since 2015.

Cusco is one of the most extraordinary cities in the world. Once the capital of the Inca Empire and now a UNESCO World Heritage Site, this Andean city sits at 3,400m above sea level and serves as the starting point for the Classic Inca Trail, the Salkantay Trek, and some of South America’s most spectacular trekking routes. Whether you have three days or three weeks, Cusco will leave a lasting impression.

At Aremika Expeditions, we are a licensed tour operator based right here in Cusco. Our team of local guides and travel specialists has been designing Cusco tours and Machu Picchu packages since 2015, and this guide reflects the real, on-the-ground knowledge we share with our travelers every day.

2. Best Time to Visit Cusco

Cusco has two distinct seasons and the timing of your visit makes a significant difference to your experience, especially if you plan to trek.

💡 Local tip: The shoulder months of April–May and September–October offer the best of both worlds — clear skies, fewer crowds and lower prices. This is our team’s personal recommendation for first-time visitors.

3. Altitude & Acclimatization in Cusco

At 3,400m above sea level, Cusco is one of the highest major cities in the world. Altitude sickness — known locally as soroche — affects a significant number of visitors regardless of age or fitness level. With proper preparation, most people adapt well within 24 to 48 hours.

How to acclimatize properly

• Rest on your arrival day — avoid strenuous activity for the first 24 hours
• Stay hydrated — drink 2 to 3 litres of water per day
• Drink coca tea — a traditional Andean remedy widely available in Cusco
• Eat light meals — heavy food makes symptoms worse in the first day or two
• Avoid alcohol — it accelerates dehydration at altitude
• Arrive gradually — consider spending a night in Lima or Sacred Valley (2,800m) before Cusco

Symptoms to watch for

Mild symptoms such as headache, fatigue and shortness of breath are normal and usually pass within a day. If you experience severe headache, vomiting, confusion or difficulty breathing, descend immediately and seek medical attention. All Aremika guides carry supplemental oxygen on multi-day treks.

💡 Medical tip: Ask your doctor about Acetazolamide (Diamox) before your trip — a prescription medication that helps the body adapt to altitude faster. Consult your GP at least two weeks before departure.

4. Top Things to Do in Cusco

Beyond being the gateway to Machu Picchu, Cusco itself is a remarkable destination with world-class archaeological sites, vibrant markets, and stunning Andean scenery within easy reach.

Must-see sites in Cusco city

• Plaza de Armas — the heart of the city, surrounded by colonial churches built on original Inca stone foundations
• Sacsayhuamán — a massive Inca fortress overlooking the city, 20 minutes uphill from the Plaza. The stonework precision is extraordinary.
• Qorikancha (Temple of the Sun) — the most important Inca temple, with Santo Domingo church built directly on top of its walls
• San Pedro Market — the best local market in Cusco for fresh produce, textiles and authentic street food
• San Blas neighbourhood — cobblestone streets, artisan workshops and the best viewpoint over the city rooftops
• Cusco Cathedral — one of the finest examples of Spanish colonial architecture in the Americas, built over 100 years (1560–1654)

Best day trips from Cusco

• 🏔️ Sacred Valley Tour — 1 day — Pisaq market, Ollantaytambo fortress, Maras salt pools

5. Getting to Machu Picchu from Cusco

Machu Picchu is located 80km northwest of Cusco at 2,430m — well below Cusco’s altitude, so many visitors feel noticeably better upon arriving. There are two main ways to reach it.

🚂 By train — the most popular option

The train from Ollantaytambo takes 1.5 to 3.5 hours to reach Aguas Calientes, followed by a 20-minute bus up to the citadel entrance. The most comfortable option for a 1-day Machu Picchu tour.

🥾 By trekking route — the most rewarding option

Arriving at Machu Picchu on foot after days of hiking through Inca ruins and Andean landscapes is an experience that stays with you for life. See our trekking section below for all available routes.

⚠️ Important: Machu Picchu has a daily visitor cap of 4,044 people divided across timed entry slots. All tickets must be purchased in advance. Our team handles all tickets, train bookings and permits as part of every tour — no queuing, no stress.

How much time do you need at Machu Picchu?

A minimum of 3 hours inside the citadel is recommended. If you want to climb Huayna Picchu Mountain or Machu Picchu Mountain for panoramic views, purchase a separate ticket and add at least 2 extra hours.

6. Best Treks from Cusco

Cusco is the trekking capital of South America, with more world-class routes within a 100km radius than almost anywhere else on Earth.
