Machu Picchu is hard to describe — photos don’t do it justice. You arrive after hours of travel, climb a winding path, pass the checkpoint, walk a bit more, and suddenly… there it is. The citadel perfect in the middle of the mountains, with Huayna Picchu behind it as guardian.

It was built in the 15th century, in the midst of mountain jungle, in a nearly inaccessible place. Why? No one knows for sure. It was a sacred city, a ceremonial center, maybe a refuge of the Inca. Whatever it was, the Incas chose a perfect spot.

The architecture is flawless. Temples aligned with the sun, agricultural terraces that prevented erosion, a water system working by gravity. Everything was intentional, nothing random.

If you have the energy (and booked in advance), climb Huayna Picchu. It’s steep, tiring, but the view from above over the entire citadel is epic. Only 200 people are allowed each day, so you must reserve months ahead.

The 4-day Inca Trail is the classic way to get there, but you have to book 6 months in advance because permits run out quickly. If you miss out, there are other routes like Salkantay that are also incredible.

Practical tip: Buy your entrance in advance, they’re sold online. There are time slots (morning and afternoon). The morning slot is better because there’s less fog. Bring water, snacks, sunscreen, and insect repellent. You can’t bring heavy food or large backpacks. Aguas Calientes has natural thermal baths that feel great after so much walking.
