This is the number one mistake. Demand is extremely high and capacity is limited.
High Season (Jun 19 - Nov 02): Book 3 months in advance if you are looking for popular routes (Huayna Picchu or Classic Route).
Key fact: There are only 1,000 tickets available in person in Aguas Calientes; don't risk waiting in endless lines.
Traveling from Cusco, visiting the citadel, and returning on the same day is exhausting.
Pro tip: Stay overnight in Aguas Calientes. This way, you can enter during the first shifts (06:00 AM), see the sunrise, and tour the site with more energy.
In the jungle eyebrow, the weather is unpredictable. Rains can occur even during the dry season.
Note: Umbrellas are prohibited, so a waterproof poncho is your best ally.
Machu Picchu is sacred and fragile. Keep in mind that the following are prohibited:
Jumping: Constant impact contributes to the sinking of the citadel (2-3 cm per year).
Others: Selfie sticks, drones, large suitcases, and eating inside the complex are not allowed.
Dry (April - October): Clear skies, but very cold nights. It is the busiest time.
Rainy (November - March): Greener landscapes and fewer people, but frequent rain.
It's not just about the luxury train. Choose the one that fits your budget and style:
Train: The fastest way via Ollantaytambo.
Inca Trail: 4 days of historic trekking (requires booking months in advance).
Hidroeléctrica: The most economical route (car + 2-hour walk).
Don't use the Valley just as a transit point. Staying overnight in places like Ollantaytambo or Urubamba helps you acclimatize better than in Cusco (they are at a lower altitude), and you can visit gems like the Maras Salt Mines or the Moray terraces.
Your palate is also on a trip! Don't leave without trying the lomo saltado, fried trout, or a good pisco sour. Local markets are excellent options for delicious and authentic food.
