Peru: Machu Picchu and the Sacred Valley

Machu Picchu earns its reputation — but the single citadel is only part of what makes this region worth the trip. The Sacred Valley around Cusco holds a full day (or three) of sites most visitors rush past on their way to the main event. Here's how to actually spend your time.
Getting there, honestly
Most visitors fly into Cusco, acclimatize for a day or two (the altitude — over 11,000 feet / 3,400m — catches people off guard more than the hike ever does), then take a train to Aguas Calientes, the town at the base of the mountain, before a short bus ride up. Book the train and your Machu Picchu entry ticket well in advance — entry is capped daily, and specific time-slotted tickets sell out during peak season (June–August).
Give yourself at least one full day in Cusco before heading to Machu Picchu. Altitude sickness is common and unpredictable, and it's a much better problem to have in a city with pharmacies and slower plans than on a hiking trail.
Beyond the citadel: the Sacred Valley

The Sacred Valley between Cusco and Machu Picchu is where a lot of the region's best texture actually lives — terraced hillsides, small weaving villages, and ruins that see a fraction of Machu Picchu's crowds. It's easy to treat the valley as a highway between two points; it's worth treating as a destination of its own for a day.
A well-known local tip: visit the valley sites in the early morning. Tour buses from Cusco tend to arrive by mid-morning, so an early start buys genuinely quiet time at places that get crowded by noon.
Maras and the salt mines

The Salineras de Maras — thousands of small salt pools terraced into a hillside, still hand-harvested using a system that dates back centuries — are one of the more striking sights in the valley and get far less attention than the ruins nearby. They're a natural pairing with nearby Moray, a set of circular agricultural terraces built to study crop growth at different microclimates.
Both sites are typically visited by car or organized tour rather than public transit; if you're short on time, they're an efficient half-day add-on from Cusco or the Sacred Valley towns.
The food is not an afterthought

Peruvian food, especially in Cusco and the Sacred Valley, deserves its own itinerary line. Ceviche gets the international attention, but the highlands have their own strong tradition — hearty soups, roasted meats, and increasingly, an ambitious modern restaurant scene in Cusco drawing on Andean ingredients most visitors have never heard of.
Industry-standard travel advice for altitude and unfamiliar food both point the same direction: ease in. Coca tea is the standard local remedy for altitude discomfort, and it's worth trying regardless — it's offered nearly everywhere.
The high Andes beyond Machu Picchu

If you have extra days, the high mountain passes outside Cusco (this stretch of road sits well above 4,000m/13,000ft) show a starkly different side of the region than the green terraces around Machu Picchu — snow-dusted peaks and a landscape that feels closer to the moon than the jungle-adjacent citadel most photos show.
This is serious altitude, even by regional standards — budget extra acclimatization time and check road conditions in the wet season (November–March), when weather can close passes with little notice.
Closing thought

Machu Picchu is worth the hype. Just don't let it be the only thing you see — the valley around it is doing a lot of the work most visitors never stop to notice.
What's worth skipping
Not every popular add-on is worth the time it takes. The Inca Trail multi-day trek requires a permit booked months in advance and is genuinely demanding — worth it only if hiking itself is part of why you're going, not just a means to see the ruins from a different angle. The train ride and bus alone deliver the destination just as well for most visitors.
