5 Days in Cusco — Inca Trails, Altitude Highs, and the Heart of Peru

I stepped off the plane at Alejandro Velasco Astete International Airport and immediately felt it — that thin, sharp air at 3,400 meters above sea level that makes your lungs work overtime and your head swim like you’ve had two glasses of wine on an empty stomach. Cusco doesn’t ease you in gently. It grabs you by the chest and says, slow down, you’re in my world now.

I’d been dreaming about this trip for years. Not in a Pinterest-board, vaguely-aspirational way, but in a genuine, dog-eared-guidebook, savings-account-dedicated kind of way. Peru had been calling to me ever since a college professor showed slides of Machu Picchu in a South American history seminar, and now, finally, I was here. Five days in the ancient capital of the Inca Empire — not nearly enough, but I was determined to make every altitude-adjusted breath count.

What I didn’t expect was how profoundly this city would rearrange my understanding of travel. Cusco isn’t just a gateway to Machu Picchu. It’s a living, breathing archaeological site layered with colonial churches built on Inca foundations, markets where Quechua women sell herbs that have been traded on the same corners for centuries, and food that ranks among the most inventive I’ve tasted anywhere in the world. Here’s how my five days unfolded.

Day 1 — Arrival, Altitude, and the Art of Doing Nothing

Every guidebook, every blog post, every fellow traveler I’d spoken to gave the same advice: do not overdo it on your first day in Cusco. Altitude sickness is real, it’s unpredictable, and it doesn’t care how fit you think you are. So I listened. For once.

My hotel in the San Blas neighborhood was a converted colonial house with thick adobe walls, a sunny courtyard, and a staff that immediately pressed a cup of coca tea into my hands. I sipped it slowly, feeling the mild numbness on my tongue, and watched hummingbirds dart between the geraniums. Not a bad start.

After a couple of hours of rest, I ventured out for a slow walk. San Blas sits above the Plaza de Armas, connected by steep cobblestone streets that would have been charming even without the altitude making every incline feel like a personal challenge. I paused frequently — not to admire the view, though it was spectacular, but because my body demanded it.

I wandered down to the Plaza de Armas as the late afternoon light turned the cathedral facade golden. Street vendors sold roasted corn and fresh juice. A brass band was practicing somewhere behind the arcades. I sat on a bench and just absorbed it all, reminding myself that sitting and watching is a perfectly valid way to experience a city.

For dinner, I found a small restaurant on Calle Procuradores — the locals call it “Gringo Alley,” which should have been a warning, but the place I chose turned out to be a genuine gem. I had a traditional Cusquenan dinner of chiri uchu — a cold dish of guinea cuy, chicken, sausage, corn, seaweed, and cheese, all arranged on a plate like edible art. The flavors were earthy and complex, nothing like what I’d imagined Peruvian food to be.

I was in bed by nine, slightly headachy but deeply content.

Day 2 — Walking Through Layers of History

I woke up feeling surprisingly human. The coca tea was working — or maybe it was the solid ten hours of sleep. Either way, I was ready to explore properly.

I’d booked a guided walking tour of Cusco’s historic center, and it turned out to be one of the best decisions of the entire trip. Our guide, Marco, was a local historian with an infectious passion for Inca engineering. He showed us things I would have walked right past on my own — the famous twelve-angled stone in Hatunrumiyoc Street, fitted so precisely into a wall that you can’t slide a razor blade between the joints, and the foundations of Qorikancha, the Inca Temple of the Sun, upon which the Spanish built the Church of Santo Domingo in what might be history’s most aggressive metaphor.

What struck me most was the contrast between Inca and colonial architecture. The Inca walls — massive, perfectly fitted polygonal stones with no mortar — have survived every earthquake. The Spanish colonial structures built on top of them have crumbled and been rebuilt multiple times. There’s a lesson in that, though I’ll resist the temptation to spell it out.

After the tour, I spent the afternoon at the Museo de Arte Precolombino, housed in a beautiful colonial mansion. The collection of Inca and pre-Inca ceramics, textiles, and metalwork was extraordinary. I stood in front of a Moche portrait vessel for a good five minutes, marveling at the individuality of the face — this was portraiture, not idealization, created over a thousand years before the Renaissance.

That evening, I treated myself to dinner at a restaurant near the Plaza de Armas that specialized in modern Peruvian cuisine. I had alpaca tenderloin with quinoa risotto and a pisco sour that could convert even the most dedicated wine drinker. The meal was exquisite, and I scribbled tasting notes on a napkin like some kind of food obsessive. Which, by that point, I suppose I was.

Day 3 — The Sacred Valley and the Weight of Empire

I’d reserved this day for the Sacred Valley, and I was glad I’d booked an organized day trip rather than trying to navigate it independently. The valley stretches northwest of Cusco along the Urubamba River, and it’s studded with Inca ruins, traditional markets, and agricultural terraces that look like giant green staircases carved into the mountainsides.

Our first stop was Pisac, where we climbed to the ruins above the town. The terraces here are staggering in scale — hundreds of concentric rings descending into the valley, each one a carefully engineered microclimate for growing different crops. The Incas were, among many other things, extraordinary agronomists. Below the ruins, the Pisac market was a riot of color: hand-woven textiles, carved gourds, silver jewelry, and heaps of dried herbs and potions promising everything from altitude relief to romantic success.

We drove on to Ollantaytambo, and this is where the day became genuinely awe-inspiring. The fortress ruins here are massive — enormous pink granite blocks hauled from a quarry across the valley and up a steep hillside, fitted together with the same impossible precision I’d seen in Cusco. Our guide explained that construction was never completed because the Spanish conquest interrupted it. Standing among those unfinished walls, I felt the abrupt violence of that interruption more viscerally than any textbook had ever conveyed.

The town below the ruins is worth exploring too. Ollantaytambo is one of the few places where the original Inca street plan is still intact and still lived in. Water channels run along the narrow stone streets, just as they did five hundred years ago. I bought a bag of roasted habas (fava beans) from an elderly woman sitting in a doorway and ate them while wandering the grid of ancient lanes.

On the drive back to Cusco, we stopped at the Moray terraces and Maras salt mines, both of which deserve more time than most tours give them. Moray’s circular terraces are thought to have been an Inca agricultural laboratory — each ring sits at a slightly different altitude and temperature, allowing experimentation with crop varieties. The salt mines at Maras, where thousands of small evaporation pools cascade down a hillside in shades of white and pink, have been in continuous use since Inca times. I bought a bag of pink salt that I still use in my kitchen today.

Day 4 — Machu Picchu, Obviously

Let’s address the elephant in the room — or rather, the lost city on the mountaintop. Yes, I went to Machu Picchu. Yes, it was everything they say it is. No, the crowds didn’t ruin it, though they came close.

I caught the early morning train from Ollantaytambo to Aguas Calientes, which meant a 4:30 a.m. wake-up call but was absolutely worth it. The train follows the Urubamba River through increasingly dramatic scenery — the valley narrows, the vegetation thickens, and the mountains close in until you’re in genuine cloud forest territory. I pressed my face against the window like an excited child.

From Aguas Calientes, a bus zigzagged up the mountainside to the entrance. I’d pre-booked a guided tour with entry, which is essential — entry slots are timed and limited, and having a guide transforms the experience from “looking at old stones” to “understanding one of humanity’s greatest achievements.”

And then there it was. That view. The one you’ve seen in a thousand photographs. Except photographs don’t capture the scale, or the sound of the wind, or the clouds threading between the peaks, or the vertigo-inducing drop on every side. Machu Picchu sits on a narrow ridge between two mountains, surrounded by sheer cliffs and cloud forest, and it looks like a place that shouldn’t exist — that couldn’t exist — and yet there it is, stone by perfectly fitted stone.

Our guide walked us through the agricultural sector, the urban sector, the Temple of the Sun, the Room of the Three Windows, and the Intihuatana stone — a carved granite pillar that served as an astronomical clock. I learned that Machu Picchu was likely a royal estate for the Inca emperor Pachacuti, not a “lost city” in any real sense. It was abandoned during the Spanish conquest and never found by the colonizers, which is why it’s so remarkably intact.

I spent about four hours on site, which felt like both an eternity and nowhere near enough. The crowds thinned in the late morning, and I found a quiet corner near the guardhouse where I could sit and simply look. I’m not normally given to spiritual experiences, but there was a stillness up there — beneath the tourist chatter and the llama photo ops — that felt genuinely sacred.

The train back to Cusco was a blur of exhaustion and contentment. I ate dinner at the first restaurant I could find near my hotel and fell asleep reading my guidebook.

Day 5 — Markets, Cuy, and Saying Goodbye

My last full day in Cusco was deliberately unstructured. I’d been on the go for four days, and I wanted to experience the city at its own pace rather than mine.

I started at the Mercado de San Pedro, Cusco’s central market, which is one of those places that assaults all five senses simultaneously. Mountains of tropical fruit I couldn’t identify, rows of fresh juice vendors, entire sections devoted to dried potatoes in dozens of varieties, stalls selling medicinal herbs, and a food court where market workers and tourists sit elbow to elbow eating bowls of soup and plates of roasted chicken.

I tried cuy — roasted guinea pig — which is the dish that every travel writer feels obligated to describe. Here’s my take: it tastes like dark-meat chicken crossed with rabbit, the skin is incredibly crispy, and there’s not a lot of meat per animal. It’s served whole, which takes some getting used to, but the flavor is genuinely good. Would I order it regularly? Probably not. Am I glad I tried it? Absolutely.

After the market, I walked up to Sacsayhuaman, the massive Inca fortress complex above Cusco. This was a steep climb that my now somewhat altitude-adjusted lungs handled with only moderate complaint. The stones here are the largest I’d seen anywhere in Peru — some weigh over 100 tons — and they’re fitted together with the same razor-blade precision. The scale is genuinely hard to comprehend. I sat on one of the walls and looked down at Cusco spread out below, terracotta roofs and church towers against the brown hills, and tried to imagine this place as the Incas knew it — the navel of the world, the center of an empire that stretched from Colombia to Chile.

I spent my last afternoon wandering the streets of San Blas, ducking into artisan workshops and small galleries. I bought a hand-painted retablo — a traditional folk art scene inside a wooden box — from an artist who showed me his workshop in the back and explained how each figure was individually molded and painted. It’s sitting on my bookshelf now, a small, vivid piece of Cusco.

For my final dinner, I splurged on one of Cusco’s high-end restaurants, where a young chef was doing extraordinary things with traditional Andean ingredients — potato foam, freeze-dried potato rehydrated in herb broth, coca leaf ice cream. It was inventive without being gimmicky, rooted in tradition while pushing forward. A perfect encapsulation of Cusco itself.

The next morning, I took a shuttle back to the airport and caught my flight to Lima with that particular heaviness that comes at the end of a trip you know has changed you, even if you can’t yet articulate how.

Practical Tips for Visiting Cusco

After five days of navigating altitude, history, and extraordinary food, here’s what I wish I’d known — and what I’d tell any friend planning the same trip.

Altitude is no joke. Cusco sits at 3,400 meters (11,150 feet). Take your first day very easy. Drink coca tea, stay hydrated, avoid alcohol for the first 24 hours, and consider asking your doctor about acetazolamide (Diamox) before your trip. I felt noticeably better by day two, but some travelers struggle for longer.

Book Machu Picchu well in advance. Entry is limited to roughly 4,000 visitors per day across several timed circuits, and popular slots sell out weeks or even months ahead, especially in high season (June-August). Buy your tickets through the official government portal and don’t rely on third-party sites.

The Boleto Turistico is essential. This tourist ticket (around 130 soles for the full version) covers entry to 16 sites in and around Cusco, including Sacsayhuaman, Pisac, Moray, and several museums. It pays for itself within two or three visits.

Getting around:

• Within Cusco, walk. The historic center is compact and best explored on foot.
• For the Sacred Valley, book an organized tour or hire a car if you want flexibility. Public colectivos run to major towns but are slow and crowded.
• For Machu Picchu, the train is the standard option. PeruRail and Inca Rail both operate services from Ollantaytambo and Poroy (near Cusco). Book early for better prices.

Best time to visit: The dry season (May-October) offers the clearest skies and best hiking conditions. I visited in June and had perfect weather with cold nights and warm, sunny days. The wet season (November-March) is cheaper and less crowded but brings daily afternoon rain.

Food recommendations:

• Try cuy at least once — the market is the most authentic (and cheapest) place to do it.
• Peruvian cuisine is world-class. Don’t stick to tourist restaurants; ask locals for recommendations.
• Chicha morada (purple corn drink) is refreshing and delicious.
• The coffee is excellent — Cusco-region beans are some of Peru’s best.

For multi-day trekking: If you have more time than I did, consider the classic four-day Inca Trail trek to Machu Picchu. Permits are limited and sell out months ahead, especially for peak season. Alternative treks like Salkantay and Lares are equally stunning and easier to book on shorter notice.

Budget notes:

• Cusco is very affordable by Western standards. A good meal at a mid-range restaurant costs $8-15 USD.
• Accommodation ranges from $10 hostels to $300+ luxury hotels. The sweet spot for comfort and character is $40-80 per night in a boutique guesthouse.
• ATMs are widely available in the city center but charge fees. Bring some USD cash as backup — it’s accepted at many tourist-oriented businesses.

What I’d do differently: I’d add at least two more days. Five days let me hit the highlights, but I felt rushed. With a full week, I’d have spent a second day in the Sacred Valley, attempted the short hike to Huayna Picchu at Machu Picchu, and explored the less-visited ruins around Cusco like Tambomachay and Puka Pukara at a slower pace.

Cusco is one of those rare places where the weight of history doesn’t feel heavy — it feels alive. The Inca walls aren’t relics; they’re foundations, literally and figuratively, for a city that’s still evolving, still cooking, still weaving, still building on what came before. I left with sore legs, a slight headache, a bag of pink salt, and the firm conviction that I’ll be back.
