Common Tourist Mistakes in Cusco (and How to Avoid Them)

After years hosting travelers, these are the mistakes we see repeated most — and they're easy to avoid once you know about them.

1. Arriving and trekking the same day

Cusco sits at 3,399 m (11,152 ft). Flying in and climbing to Machu Picchu or doing a demanding hike the next day is a recipe for altitude sickness. Give your body at least 1-2 days to acclimate. See our altitude sickness guide.

2. Packing the itinerary too tight

Seeing Machu Picchu, the Sacred Valley, Rainbow Mountain and Humantay Lake in 2 days is possible on paper, but exhausting and risky for altitude sickness. Check our realistic 3-day itinerary or the 7-day one if you have more time.

3. Buying the Machu Picchu ticket last minute

In high season (June-August) the most requested circuits sell out weeks ahead. Booking 1-2 months in advance gives you more options and better pricing.

4. Not carrying cash in soles

Many markets, public restrooms, tips and local communities (like the one at Humantay Lake) only accept cash. Cards don't always work outside downtown.

5. Underestimating the cold at night

By day the Cusco sun can burn, but at night temperatures drop fast, especially between May and August. Pack layers, not just sunscreen.

6. Not confirming the operator's real authorization

Informal operators exist that charge the same but have no permits or insurance. Verify the operator is MINCETUR-authorized before booking.

7. Ignoring the cancellation policy before booking

Travel plans change: flights delay, people get altitude sickness. Read the operator's cancellation policy before paying, not after.

8. Not comparing train options in advance

The Machu Picchu train's cost varies a lot by time and how early you buy. See our train guide to avoid overpaying.
