What to Do in Cusco Before the Inca Trail: A Practical 2–3 Day Plan to Acclimatize, Prepare and Avoid Common Mistakes

You can train for months, buy the best hiking gear, and carefully plan your Inca Trail adventure—but if you overlook your first couple of days in Cusco, you're making one of the most common mistakes first-time trekkers make.

At 3,400 m (11,150 ft) above sea level, Cusco isn't just the gateway to Machu Picchu; it's where your body begins adapting to high altitude. Those 48 to 72 hours before your trek can make the difference between enjoying the experience and struggling through the first days with headaches, fatigue, or digestive problems.

Most guides focus on attractions like San Blas, the Plaza de Armas, or the Sacred Valley. While those places are absolutely worth visiting, they rarely explain how to use your time in Cusco to prepare for the Inca Trail itself.

This guide takes a different approach.

Instead of simply listing things to do, you'll learn:

• How many days you should spend in Cusco before the Inca Trail
• A practical 2-day acclimatization plan
• Which activities help—and which can hurt—your preparation
• What to eat (and what to avoid)
• How to test your hiking gear before the trek
• What to organize the evening before departure
• The small mistakes that experienced hikers wish they'd avoided

If your goal is to arrive at Kilometer 82 feeling prepared instead of anxious, this guide is for you.

Why the Days Before the Inca Trail Matter More Than You Think

One of the biggest misconceptions about the Inca Trail is that physical fitness alone is enough.

It isn't.

Even experienced runners, cyclists, and hikers can feel the effects of altitude when they arrive in Cusco. The lower oxygen levels affect everyone differently, regardless of age or fitness level.

Many first-time visitors make one of two mistakes:

• They treat Cusco as a city break and try to do too much too soon.
• They spend their time resting completely, missing the chance to adapt gradually.

The ideal approach sits somewhere in the middle.

Your goal during these first days isn't to train harder—it's to help your body adapt while keeping your energy for the trek ahead.

The mistake I made on my first afternoon

If someone had told me that the Inca Trail actually starts the day before you reach Kilometer 82, I would have avoided a couple of painful lessons.

I arrived in Cusco feeling confident. Back home I was doing cardio almost every day, so I assumed the altitude warnings were exaggerated.

A few hours after landing, I made what is probably the most common mistake.

I ordered a huge traditional Peruvian meal near Plaza de Armas because I was starving after the flight.

Three hours later, I was lying in my hotel bed with a pounding headache and one of the slowest digestions I've ever experienced.

The hotel staff brought me cup after cup of muña tea, explaining that many visitors underestimate how differently their bodies react at altitude.

That afternoon completely changed how I approached the rest of my stay.

Instead of trying to "make the most" of every hour, I focused on eating lighter meals, drinking plenty of water, and letting my body catch up.

Ironically, those small adjustments probably helped me enjoy the Inca Trail much more than another afternoon of sightseeing would have.

How Many Days Should You Spend in Cusco Before the Inca Trail?

The short answer is:

Plan to spend at least 2 full days in Cusco before starting the Inca Trail. Three days is even better if your itinerary allows it.

Here's why.

Time in Cusco	Recommended?	Why
Same day	❌ No	Very high risk of altitude discomfort and fatigue.
1 day	⚠️ Not ideal	Better than nothing, but your body has very little time to adapt.
2 days	✅ Recommended	Enough time for most travelers to begin acclimatizing.
3 days	⭐ Ideal	More comfortable pace and additional flexibility if you feel tired.

Everyone acclimatizes differently.

Some travelers feel perfectly normal within hours, while others may experience headaches, reduced appetite, shortness of breath, or poor sleep during the first couple of days.

That's completely normal.

Rather than trying to "beat" the altitude, your goal is simply to give your body enough time to adjust.

What Should You Prioritize During Those Days?

Think of your preparation in four areas:

1. Acclimatization

Your body needs time.

Stay hydrated.

Sleep well.

Avoid unnecessary physical stress.

2. Gentle Movement

Walking actually helps.

Long, relaxed walks around Cusco are far more useful than staying in bed all day.

The key is intensity.

You should finish your walks feeling energized—not exhausted.

3. Equipment Check

Cusco is the perfect place to discover problems before they become serious.

This includes:

• Boots
• Backpack fit
• Socks
• Trekking poles
• Rain gear
• Layers

Every small issue you solve here becomes one less problem on the trail.

4. Logistics

Many hikers underestimate how much organization happens before the trek begins.

Use these days to:

• Confirm your passport is ready.
• Organize your duffel bag.
• Buy forgotten gear.
• Withdraw cash if needed.
• Attend your operator's briefing.

You'll thank yourself later.

A Practical 2-Day Acclimatization Plan

The purpose of this itinerary isn't to see every attraction in Cusco.

It's to help you arrive at the Inca Trail healthy, rested, and confident.

Day 1: Recover, Hydrate and Let Your Body Adjust

If you've just landed, especially after a long international flight, this day should be intentionally easy.

You don't lose anything by slowing down.

In fact, you'll probably gain much more energy for the days ahead.

Morning

If you arrive early:

• Check into your accommodation.
• Drink water regularly.
• Have a light breakfast or snack.
• Resist the temptation to immediately start sightseeing.

Many hotels in Cusco offer coca tea or muña tea upon arrival. While many travelers enjoy these traditional herbal drinks as part of their acclimatization routine, remember that they are not a substitute for proper hydration, rest, or medical advice if you develop severe altitude symptoms.

Lunch

This is where I learned my first lesson.

After arriving hungry from my flight, I ordered one of the biggest meals on the menu.

At sea level, it probably wouldn't have mattered.

At 3,400 meters, it was a different story.

For the rest of the afternoon, I felt bloated, sluggish, and completely drained.

Looking back, I would have chosen something much lighter.

Good first-day options include:

• Quinoa soup
• Grilled chicken with rice
• Fresh vegetables
• Trout
• Light pasta
• Plenty of water

Heavy fried food, oversized portions, and excessive alcohol can wait until after the trek.

Your stomach will probably thank you.

Afternoon

Instead of trying to visit every attraction, choose one or two easy activities.

Good options include:

Explore Plaza de Armas

Take your time.

Sit on a bench.

Watch daily life unfold.

Visit the cathedral if you're interested in history.

The objective isn't to rush—it's simply to spend time outdoors while moving gently.

Visit San Pedro Market

This is one of the best places to experience local life without climbing endless hills.

You can browse fruit stalls, fresh juices, local snacks, and handmade products while walking at your own pace.

It's also a convenient place to buy small travel essentials if you've forgotten something.

Have an Early Dinner

Aim for another light meal.

If you're still adjusting to the altitude, there's no prize for eating the largest local specialty on your first night.

Simple food often works best.

Evening

Before going to bed:

✔ Refill your water bottle.

✔ Charge your electronics.

✔ Lay out comfortable clothes for tomorrow.

✔ Get as much sleep as possible.

Even if excitement makes it difficult to fall asleep, giving yourself extra time to rest can help you feel more refreshed the following day.

End of Day 1

By the end of your first day in Cusco, you shouldn't be asking:

"How many attractions did I visit?"

Instead, ask yourself:

• Do I feel better than when I arrived?
• Am I eating normally?
• Can I walk comfortably without feeling exhausted?
• Is my body adapting?

If the answer is yes, you're exactly where you want to be.

Day 2: Walk, Test Your Gear and Build Confidence

By your second day in Cusco, you should hopefully feel more comfortable than when you arrived. You may still notice the altitude when climbing stairs or walking uphill, but that's completely normal.

This is the ideal day to move a little more, explore beyond the historic center, and make sure both you and your gear are ready for the Inca Trail.

Remember, this isn't a training day. You're not trying to improve your fitness in the final 24 hours—you've already done that at home. Today is about building confidence and spotting small issues before they become big problems on the trail.

Morning: Take a Walk Through San Blas

If there's one place I'd recommend before the Inca Trail, it's San Blas.

The neighborhood's narrow cobblestone streets and gentle but continuous climbs make it the perfect place to see how your body responds to altitude.

What surprised me most wasn't the steepness—it was how quickly I ran out of breath.

Back home, I would have walked up those streets without thinking twice. In Cusco, I realized I needed to slow down almost immediately.

Instead of fighting the altitude, I started taking shorter steps and matched my breathing to my pace:

• Inhale for two steps.
• Exhale for two steps.
• Repeat.

It sounds incredibly simple, but it completely changed how I felt. Within a few minutes, walking became much more comfortable.

That same steady rhythm would become one of the most useful habits during the Inca Trail itself.

Use This Walk to Test Your Boots

Many hikers know they shouldn't wear brand-new boots on the Inca Trail.

Far fewer actually test them before the trek.

San Blas is an excellent place to do exactly that.

Pay attention to:

• Heel movement
• Toe pressure on downhill sections
• Hot spots or rubbing
• Lace tension
• Overall comfort

I discovered a slight rub on my right heel after only fifteen minutes.

It didn't seem like a big deal—but on a four-day trek, that tiny irritation could easily have turned into a painful blister.

Back at the hotel, I covered the area with medical tape and switched to thicker merino wool socks.

It felt like such a small adjustment at the time.

Looking back, it probably saved me from dealing with blisters during the hardest days of the hike.

Pro tip: If you notice discomfort in Cusco, fix it immediately. Don't assume it will magically disappear once you're on the trail.

Optional Afternoon Activities

After your morning walk, choose one activity that keeps you moving without overloading your body.

Good options include:

Visit Sacsayhuamán

The archaeological site is close to Cusco and offers spectacular views over the city.

The walk uphill can feel challenging because of the altitude, so take your time and stop whenever you need to.

This isn't a race.

Explore the Sacred Valley

If your itinerary allows, spending part of the day in the Sacred Valley can be an excellent choice.

Towns like Pisac and Ollantaytambo sit at a lower altitude than Cusco, which some travelers find more comfortable while acclimatizing.

It's also a chance to experience local markets, Inca ruins, and beautiful mountain scenery without committing to a strenuous hike.

Just avoid trying to fit too many stops into a single day.

Shop for Last-Minute Gear

Cusco has plenty of outdoor stores where you can replace forgotten items or upgrade your gear.

Common purchases include:

• Rain ponchos
• Gloves
• Headlamps
• Trekking pole accessories
• Water bottles
• Buffs
• Sunscreen
• Dry bags
• Extra socks

Buying a forgotten item today is much less stressful than searching for it at 9 p.m. the night before your trek.

What NOT to Do Before the Inca Trail

Many guides tell you where to go.

Just as important is knowing what to avoid.

The following mistakes are surprisingly common—and completely preventable.

Avoid	Why
Heavy meals	Digestion often feels slower at high altitude, especially during your first days. Choose lighter meals until you feel fully adjusted.
Too much alcohol	Alcohol can contribute to dehydration and may make altitude symptoms feel worse.
Extreme hikes before the trek	Save your energy for the Inca Trail itself. Challenging hikes like Rainbow Mountain or Humantay Lake are better enjoyed before or after your trek—not immediately beforehand.
Trying to "push through" altitude symptoms	If you develop persistent or worsening symptoms, rest and seek medical advice rather than forcing yourself to continue sightseeing.
Breaking in new gear	New boots, backpacks, or clothing should always be tested before the trek.
Ignoring hydration	Drink water regularly throughout the day rather than waiting until you feel thirsty.
Packing at the last minute	Organizing everything the night before often leads to forgotten essentials and unnecessary stress.

The goal isn't to spend two days wrapped in bubble wrap.

It's simply to arrive at the trailhead with as much energy as possible.

The Evening Before Your Trek: The Checklist Most Travelers Wish They Had

This is the part almost nobody talks about.

Most articles stop after recommending coca tea and a visit to San Blas.

But in reality, the evening before the Inca Trail is when everything suddenly becomes real.

Your operator holds the briefing.

You receive final instructions.

You meet your guide.

And then you return to your hotel with one mission:

Get everything ready before the 4 or 5 a.m. pickup.

The Duffel Bag Surprise

After our briefing, the guide handed each of us a duffel bag that the porters would carry.

Then came the announcement:

"Everything inside this bag—including your sleeping bag if you're renting one—must stay within the operator's weight limit."

That was the moment I realized I had packed far too much.

Back at the hotel, I spread everything across the bed and started weighing items one by one.

Suddenly, every decision mattered.

Did I really need three thermal shirts?

Probably not.

Could I transfer sunscreen into a travel-size container?

Absolutely.

Did I need an extra pair of trousers?

Not really.

For nearly an hour, I removed small items until my bag finally met the required weight.

It was a simple exercise, but it taught me something important:

The lighter your duffel bag, the easier it is to stay organized throughout the trek.

Always check your operator's current weight allowance, as it can vary.

The Small Item I Almost Forgot

Just when I thought everything was ready, I looked at my trekking poles.

That's when I realized I was missing rubber tips.

Some operators and protected areas require trekking poles to have rubber covers to help protect the historic stone trail.

At nearly 9 p.m., I found myself rushing through Cusco looking for an outdoor shop that was still open.

Fortunately, I found one.

Had I waited until the next morning, it would have been too late.

It's a perfect example of why checking your equipment the night before matters so much.

One Last Lesson

By the time I finally climbed into bed, everything was ready.

The passport was sealed inside a waterproof bag.

My boots were waiting by the door.

The duffel bag was packed.

The alarm was set for before dawn.

I didn't sleep particularly well—mostly because I was too excited.

But unlike the day I arrived in Cusco, I wasn't worried anymore.

I'd already made the mistakes.

I'd already fixed them.

The next morning, when our bus pulled up to Kilometer 82, there was only one thing left to do:

Start walking.
