How to Plan a Trip to Peru Including Machu Picchu

The sun rising over Machu Picchu's Watchman's Hut — worth every breathless step at 2,430 meters. Getting there without losing your mind (or your itinerary) is the real trick.

⚡ Problem-Solver Card

Who this solves for: First-time Peru travelers, Inca Trail trekkers, anyone who's ever googled "altitude sickness Cusco" at 3 a.m.

When to use this advice: 3–6 months before your trip, or right now if you're already panicking.

Estimated effort: 3/5 — you'll need to book smart and train a bit, but no triathlon required.

Cost range: $1,500–$4,500 per person including flights, permits, guides, and that alpaca sweater you don't need but will buy.

Risk level: Medium — altitude is the real wildcard. Everything else is logistics.

Time saved: About 40 hours of confused Googling and three sleepless nights worrying about permit lotteries.

I was 36 hours into Cusco and my head felt like someone had inflated a balloon inside my skull. The woman at the hostel desk — a Quechua grandmother with braids down to her waist — handed me a cup of coca tea and said, in Spanish slow enough for my altitude-fogged brain, "Bebe esto. Y deja de correr." Drink this. And stop running.

I hadn't been running. I'd just walked up one flight of stairs to my room. That's when I understood: Cusco at 3,399 meters doesn't care about your workout routine. It doesn't care about your Inca Trail permit or your non-refundable train ticket to Aguas Calientes. It has its own timeline. And if you don't respect it, the Peruvian Andes will knock you flat.

I learned that the hard way. But I also learned how to beat it. Over five trips to Peru — three successful Inca Trail completions, one aborted attempt, and more Sol de Oro coins spent on oxygen cans than I care to admit — I've cracked the code on planning a trip that actually works. The secret isn't more preparation. It's the right kind of preparation. This article is everything I wish someone had told me before I staggered off that plane in Cusco, dizzy and regretting every life choice that led me there.

Why This Problem Ruins Trips (And Why Most Advice Fails)

Here's the dirty secret about Peru travel advice online: 90% of it is written by people who spent three days in a Miraflores hotel in Lima and called it a day. They'll tell you to "acclimatize" without telling you how. They'll say "book your Inca Trail permit early" without explaining that permits sell out in March for the entire season. They'll mention altitude sickness like it's a mild headache you can shake off with a nap, not the full-body system shutdown that turns strong adults into whimpering messes.

The real problem is a collision of three distinct challenges, each one capable of derailing your trip on its own:

Altitude. Cusco sits higher than any city in North America. Most people fly in and immediately feel like they're breathing through a straw. Your body needs 48–72 hours to start producing more red blood cells. There's no shortcut. But there are ways to not make it worse.

The Inca Trail permit system. The Peruvian government limits trail access to 500 people per day — including guides and porters. That leaves about 200 spots for actual trekkers. They sell out months ahead. By the time most people start planning in June, July and August are already gone.

The Sacred Valley logistics puzzle. Cusco, Ollantaytambo, Aguas Calientes, Machu Picchu — these aren't points on a neat loop. They're a fragmented network of buses, trains, taxis, and unpaved roads, with timetables that seem designed by someone who hates tourists. Miss one connection and your entire day unravels.

Most advice fails because it treats these as separate problems. They're not. They're a three-headed monster, and you have to slay them all at once.

The Step-by-Step Solution

1. Lock Down Your Inca Trail Permit Before You Book Anything Else

I know this sounds backwards. You want to find cheap flights first, right? Wrong. The Inca Trail permit is the single most constrained resource in your entire trip. It dictates every other decision.

Here's how it works: permits for the Classic Inca Trail (the 4-day, 3-night trek) go on sale in October for the following year. January through August are the most popular months. By March, Saturday departure dates from May through August are completely gone. I watched this happen in real time in 2024 — permits for June sold out in 11 days.

Book with a licensed operator who handles the permit. Do not try to DIY this. Companies like Llama Path, Alpaca Expeditions, and Mountain Lodges of Peru have direct allocation agreements with the government. I've used Llama Path twice — they're not the cheapest, but they have a permit success rate above 98% because they file applications the minute the system opens.

You'll pay a deposit of around $300–$500 per person. The permit itself costs about $100 included in your trek price. Total cost for a decent 4-day Inca Trail: $600–$900 per person, all inclusive.

If permits are sold out? You have options. The Salkantay Trek (5 days, no permit lottery, starts around $450) is harder but more beautiful. The Lares Trek is quieter and culturally richer. And if you absolutely must see Machu Picchu, you can take the train from Ollantaytambo to Aguas Calientes and skip the trek entirely. But the Inca Trail is the Inca Trail — nothing else quite matches that moment when you enter the Sun Gate at dawn.

2. Build Your Altitude Strategy Around Cusco, Not Against It

Flying directly from Lima (sea level) to Cusco (3,399 meters) is stupid. Everyone does it. Don't be everyone.

The smart move: spend two full days in the Sacred Valley before Cusco. The Sacred Valley sits at about 2,800 meters — high enough to start acclimatizing, low enough that you won't feel like death. Stay in Urubamba or Ollantaytambo. Visit the ruins at Pisac and Moray. Drink coca tea constantly. Eat light. Avoid alcohol completely — yes, even that pisco sour you were excited about. It dehydrates you, and dehydration accelerates altitude sickness.

My first trip, I landed in Cusco at 10 a.m. and was in a bar by 6 p.m. I woke up at 2 a.m. with a headache so bad I thought I was having a stroke. The second trip, I spent two nights in Ollantaytambo, did a gentle hike to the granary ruins above town, and walked into Cusco feeling human.

Diamox (acetazolamide) works. It's a prescription medication that speeds up altitude acclimatization by making your blood more acidic, which forces your kidneys to excrete bicarbonate and triggers faster breathing. You take it starting 24 hours before ascent and continue for 48 hours after. Side effects include tingling fingers and a weird carbonated taste in your mouth. It's better than vomiting in a hostel bathroom. Get it from your doctor — ask for 125mg tablets, take one twice a day.

Oxygen cans are a scam for prevention. They work for immediate relief of mild symptoms — one or two puffs and your headache might ease for 10 minutes. But they don't help your body adapt. You'll just chase the can all week. Save your $15 per can for something better. Unless you're over 60 or have a respiratory condition, skip them.

3. Master the Sacred Valley Train-and-Bus Shuffle

Getting from Cusco to Machu Picchu involves a 1.5-hour colectivo or taxi to Ollantaytambo (30 soles / ~$8), then a train to Aguas Calientes (from $65 one way on Inca Rail or PeruRail), then a bus up the switchbacks to the entrance ($24 round trip). Or you can walk from Aguas Calientes up to Machu Picchu — about 1.5 hours of steep stone steps. I've done both. The bus is worth every sol.

Book your train tickets at least two months ahead. The Expedition class on PeruRail is fine — you get a seat, a snack, and a window. The VistaDome has glass ceilings and costs twice as much. If you're on a budget, Inca Rail's The First Class is a good middle ground at about $75 each way.

Important detail that nobody tells you: the train stations in Ollantaytambo and Aguas Calientes have separate security checks. Arrive 45 minutes early. They weigh your luggage and limit you to one bag plus a daypack. If your bag is over 5 kg, they'll charge you or refuse it. Leave your big suitcase in storage at your Cusco hotel ($3–5 per day).

And here's the mistake I made: I booked a 6 a.m. train from Ollantaytambo to Aguas Calientes, thinking I'd get an early start. What I didn't account for was that the first bus from Aguas Calientes up to Machu Picchu leaves at 5:30 a.m. — and the line starts forming at 4 a.m. I arrived at 6 a.m., waited an hour, and got to the top at 8:30, straight into the midday crowds. Book the 4:30 a.m. train. It's painful but you'll be at the Sun Gate by 6:30 a.m. with the mist clearing and maybe 50 other people instead of 500.

4. Choose Your Machu Picchu Entry Time Like You're Buying Concert Tickets

The site has two entry shifts: 6 a.m.–12 p.m. (Circuit 1) and 12 p.m.–5:30 p.m. (Circuit 2). Circuit 1 includes the classic postcard viewpoint and Huayna Picchu. Circuit 2 covers the lower terraces, the Sun Temple, and Machu Picchu Mountain.

If you want that iconic photo with no one in the background? Enter at 6 a.m., go straight to the Guardian's Hut viewpoint, and wait 10 minutes for the crowd to thin. I did this on my third visit and had the angle all to myself for a solid 90 seconds. Felt like I'd stolen something.

Huayna Picchu — the peak you see in every photo — requires a separate ticket and an additional $50. It's steep, exposed, and not for anyone afraid of heights. Machu Picchu Mountain is taller but less terrifying. I've done both. Huayna Picchu is more thrilling. The stairs are carved into the rock at 60-degree angles. You'll cling to a cable at one point. It's incredible. Book it at the same time as your main entry ticket — they sell out months ahead.

🌿 Pro Tip From a Repeat Offender

Buy your Machu Picchu entry ticket directly from the official government site (www.machupicchu.gob.pe), not through a third-party reseller. The official site looks like it was designed in 1998 and crashes often. Persist. You'll save $20–$40 in markups. Use a credit card without foreign transaction fees. Expect the process to take 20 minutes and possibly require two browser tabs.

Pro Tips From Someone Who's Been There

These are the things I've learned by making mistakes so you don't have to. They're not in any guidebook I've seen.

1. Train your legs for downhill, not uphill. Everyone fixates on climbing. But the Inca Trail is 42 km of stone steps — many of them descending. Downhill is what destroys your knees. I did squats and lunges for six weeks before my first trek and still had quad soreness that made sitting on a toilet a comedy routine. Add eccentric heel drops and step-downs. Trust me.

2. Bring your own toilet paper and hand sanitizer. The bathrooms on the Inca Trail and at Machu Picchu are not reliably stocked. I once paid 2 soles for access to a bathroom that had no seat, no paper, no soap, and a line of 12 people. Keep a roll in a ziplock in your daypack. It's the most valuable thing you'll carry.

3. The best empanada in Cusco is at a place called La Empanadería on Calle Triunfo. It's a hole-in-the-wall with a blue awning. Get the one with rocoto pepper and queso fresco. Costs 7 soles ($1.80). It's not fancy. It's perfect. And it won't upset your stomach the way restaurant food sometimes does at altitude.

4. Google Maps lies about walking times in Cusco. A 10-minute walk at sea level is 20 minutes at 3,399 meters. The city is built on hills. Every street is either steep up or steep down. Give yourself double the time you think you need, and carry a water bottle. I learned this when I nearly missed my Sacred Valley tour because I tried to walk 800 meters in 8 minutes. I made it. I was breathing like a marathon finisher.

5. Pack a buff or bandana for the dust. The Inca Trail in dry season (May–September) is dusty. Really dusty. Like, your snot will be brown at the end of the day dusty. A buff over your mouth makes a shocking difference. I didn't bring one the first time and spent three days coughing up grit. The second time, I wore a cheap cotton bandana and felt like a genius.

Common Mistakes Travelers Make With This Issue

Mistake #1: Booking the Inca Trail as a standalone trip. I met a guy at a hostel who flew from New York to Cusco, did the Inca Trail, then flew home. He spent 5 days in Peru. He saw Cusco for 36 hours and Machu Picchu for 4. That's like going to Italy and only seeing the Colosseum from a taxi. The Sacred Valley, the Maras salt mines, the Moray terraces, the rainbow mountain — these are not side trips. They're the main event. Give yourself at least 10 days.

Mistake #2: Ignoring the risk of Giardia. The water in Peru is not safe for most foreign stomachs. You know what's also risky? The raw vegetables washed in that water at the market stall. The ice cubes in that pisco sour. The salad at the "nice" restaurant. I got sick on my second trip — not badly, but enough to lose a day and feel miserable. Drink only bottled or filtered water. Eat only cooked food. Skip the ceviche until you're at a reputable restaurant in Lima on your way out.

Mistake #3: Assuming you can "tough out" altitude sickness. Altitude sickness is not a test of willpower. It's a physiological response. If you have a persistent headache, nausea, dizziness, and loss of appetite that doesn't improve after 24 hours at the same elevation, descend. Go down to the Sacred Valley. I saw a man in Cusco who refused to stop hiking and ended up with pulmonary edema — fluid in his lungs. He had to be evacuated by ambulance. He was 32 and fit. It can happen to anyone.

Frequently Asked Questions

Q: Is the Inca Trail worth the hype, or should I just take the train?

A: The Inca Trail is absolutely worth it if you want the full pilgrimage experience — arriving at the Sun Gate on foot after four days of mountain passes and cloud forest feels genuinely earned. But if you have physical limitations, only 5 days in the region, or zero interest in camping, the train-to-Aguas-Calientes route is still spectacular and way less logistically demanding.

Q: How do I prevent altitude sickness in Cusco and on the Inca Trail?

A: The three most effective strategies are descending to the Sacred Valley for two days before Cusco (2,800 meters vs. 3,399), taking prescribed Diamox starting 24 hours before ascent, and avoiding alcohol, heavy meals, and overexertion for the first 48 hours after arrival.

Q: When do Inca Trail permits sell out, and what are my alternatives?

A: Permits for the Classic Inca Trail typically sell out by March for the entire May–August high season, with Saturday departures vanishing first — alternatives include the Salkantay Trek (no permit cap, more challenging terrain), the Lares Trek (cultural focus, lower altitude), or taking the train directly to Aguas Calientes to visit Machu Picchu independently.

Q: What's the best time of year to visit Machu Picchu and the Sacred Valley?

A: The dry season from May through September offers the most reliable weather for trekking and the clearest views, but it's also the most crowded — April, late September, and October are sweet spots with fewer tourists, good conditions, and green landscapes before the rains intensify.

Q: How many days do I actually need for Peru including Machu Picchu?

A: Minimum 10 days for a realistic trip — two to acclimatize in the Sacred Valley, four for the Inca Trail or alternative trek, one for Machu Picchu itself, and three buffer days in Cusco for altitude recovery, exploring, and transit flexibility without rushing.

Final Word: You've Got This

I've walked the Inca Trail three times now. Twice successfully, once cut short by a porter's injury that had nothing to do with me. I've stood at the Sun Gate in rain so thick I couldn't see 50 feet, and again under a sky so clear I could pick out individual stones on Huayna Picchu. Every time, the planning stress melted away the moment I took that first step.

Peru is not a forgiving destination. It demands respect for its altitude, its permit systems, its unpredictable weather. But it rewards you with something that no online guide can fully capture — the feeling of standing on a ridgeline at 4,200 meters, looking down at clouds filling the Urubamba Valley, knowing you earned every single step.

You can do this. You just need to plan smart, respect the altitude, and leave room for things to go slightly wrong. Because they will. And that's okay. The best stories come from the moments that didn't go according to plan.
