If you’ve just landed in Cusco, you’re probably feeling that mix of exhilaration and thin air. The Andes welcome you at 3,399 m (11,152 ft), and your first 24–48 hours can make or break the rest of your trip.
This guide compares two perfect Day-1 options: the Sacred Valley (1-day) and the Cusco City Tour (half-day). It explains how to use them (plus a few gentle activities) to acclimatize smarter. Read this before you book or step out of your hotel.
Why Acclimatization Matters?
Altitude isn’t about toughness, it’s biology. At high elevation, the air has less oxygen and your body needs time to adapt. Move too fast, and you’ll trade views for headaches, fatigue, and missed experiences.
A deliberate, low-key first day helps your sleep, energy, and mood. Improve how you enjoy Machu Picchu, high-altitude hikes, and the rest of your Peru trip.
The Basics: What Happens to Your Body at Altitude?
- Less oxygen: faster breathing & higher heart rate.
- Common mild symptoms: headache, shortness of breath, nausea, insomnia.
- Concerning symptoms (seek help): severe breathlessness, confusion, fainting.
- Key fixes: hydrate, rest, eat lightly, and avoid alcohol.

Most healthy travelers acclimatize quickly with the right pacing.
Why your first day tour choice matters?
Tours vary in altitude, exertion, and exposure:
- Some tours descend from Cusco, easier for acclimatization.
- Some stay at the same altitude: gentle but less restorative.
- Some go much higher: not recommended on arrival day.

Sacred Valley and Cusco City Tour are the two top first day choices, each with a different acclimatization benefit.
Sacred Valley vs. Cusco City Tour
| Factor | Sacred Valley (1-Day) | Cusco City Tour (Half-Day) |
| Altitude | 2,700–2,900 m (lower than Cusco) | 3,399 m (same as Cusco) |
| Pace | Full day, mostly gentle driving + easy walks | Half day, short walks between sites |
| Best for | Descend & recover; nature & markets | Short intro, architecture & Inca sites |
| Acclimatization score | ★★★★★ (excellent) | ★★★★☆ (good) |
| Time required | Full day | Half day |
Option A Sacred Valley: The Gentle, Smart First Day
Why it helps: The Sacred Valley sits 600–700 m lower than Cusco. That drop eases breathlessness, improves appetite, and lets you move and sleep better.
What you’ll do: Scenic drives, Pisac market, gentle walks at Ollantaytambo, cultural stops in Chinchero. Activity is steady but not strenuous.
Perfect if you: Arrived that morning, plan hikes soon after, travel with family, or prefer nature over stairs.
Bottom line: If you want to recover faster and still explore, pick the Sacred Valley.

Option B Cusco City Tour: The Cultural Warm-Up
Why it helps: The City Tour keeps you close to your hotel and medical resources while introducing you to Inca history: Qoricancha, Sacsayhuamán, Q’enqo, Puca Pucara, Tambomachay.
What you’ll do: Short, interpretive walks and viewpoints. The pace can be easily adapted to rest stops.
Perfect if you: Slept a night in Cusco already, feel OK at altitude, or want a half-day introduction before deeper trips.
Bottom line: If you prefer history and short walks without leaving the city, this is a safe, meaningful Day-1 choice.

Day-1 Alternatives: Other Easy Things to Do While Acclimatizing
If you want something even gentler than a full tour, these are low-effort, high-value options:
- San Blas neighborhood stroll: art shops, viewpoints, cafés; go slow.
- San Pedro Market: taste local fruits, herbal teas, and light eats.
- Planetarium Cusco: nighttime experience that’s low exertion but high wonder.
- Cristo Blanco viewpoint: short transfer, panoramic city views.
- Cooking class: stay seated, learn, taste, rest.
All of these keep movement light but let you engage culturally, perfect for Day 0 or Day 1.



A Suggested 3-Day Acclimatization Plan
Day 0 Arrival: Rest at hotel, hydrate, light walk around Plaza de Armas, early dinner.
Day 1 Gentle Choice: Sacred Valley, if you arrived same day or Cusco City Tour, if you slept already.
Day 2 Medium Activity: Short hikes or visits at moderate altitude (e.g. Sacred Valley deeper stops, or Cusco museums).
Day 3 Higher Activity: If Day 2 went well, choose big hikes or long day trips (Rainbow Mountain, 7 Lakes, or head to Machu Picchu).
This pacing gives your body time, and preserves the energy you’ll need for the highlights.

FAQS
Do I need to acclimatize before Machu Picchu?
Yes. Spend 1–2 nights in Cusco before heading to major hikes or Machu Picchu if possible.
Can I fly into Cusco and do tours the same day?
You can, but choose low-effort options (Sacred Valley is better than high-altitude hikes). Avoid strenuous activity that same day.
How long does acclimatization take?
Most people adapt within 48–72 hours, but listen to your body — it varies.
What should I NOT do on Day 1?
Avoid Rainbow Mountain, Humantay, 7 Lakes, or any activity above 4,000 m on arrival day.
Where should I stay, Cusco or Sacred Valley first?
Cusco is the best base for transport and services, but staying a night in the Sacred Valley can be excellent for easing into altitude.
Are there any other companies I can trust for my acclimatization day tours?
Yes, we strongly suggest, for their experience and top level service:
