# Inca Highlands

The Inca Highlands, the center of Inca civilization in Peru, features numerous attractions, notably the world-famous Machu Picchu (the "Lost City of the Incas") and the Inca Trail which leads to it. There are numerous other attractions in and around the city of Cusco (the Inca capital) and the neighboring Sacred Valley, and many treks and adventure sports in the surrounding mountains and valleys.

## Understand

Cusco was the capital of the Inca Empire, and the area is the center of Inca culture, of which the most popular destination is Machu Picchu and the most popular trek is the Inca Trail. However, there are many other sights and activities in the area, and Cusco itself is full of culture: once up there, there's a lot to explore. It's unique and distant: this is a classic once-in-a-lifetime trip.
Cusco is also at high altitude (3400 m), and most treks, the Inca Trail included, are demanding, high-altitude hikes, going up to 4200 m (Inca Trail) or more, so altitude sickness is a serious concern: flying into Cusco and immediately hiking the Inca Trail is very likely to cause sickness. However, the Sacred Valley is significantly lower, though still at altitude (~2800 m), and is thus an excellent place to acclimatize initially, followed by ascending to Cusco. Machu Picchu itself is not very high (~2400 m) and thus is easy from Cusco. Other treks may be lower and less demanding, like the Lares valley trek, or higher and more demanding, like the Salkantay trail. See #Stay safe below.

## Prepare

Due to the need to acclimatize to the altitude (particularly before embarking on a trek or other physical activity), and the remoteness, there is a relatively standard itinerary: first light tourism while acclimatizing, then the trek, then home.
See Inca Trail#Prepare. Key points:
* If hiking the Inca trail:
** Book at least 6 months in advance: the Inca Trail requires individual dated tickets far in advance.
** A tour company is required on the trail: choose it carefully, depending on the type of trek you want, and conscious of their treatment of workers, notably porters.
* If hiking other treks:
** Advanced booking is not required: you can book a day or two ahead of time in Cusco.
** No tour company is required, though they are useful, not least for language.
* Buy or plan to rent trekking equipment, and break in shoes or boots.
* Get a prescription for acetazolamide (ACZ) if taking to prevent altitude sickness. You may be able to get in Peru, but it's easier beforehand.

## Get in

Per Peru#Get in, fly into Lima, thence Cusco (bus between Lima and Cusco possible but long).

## Get around

To visit sites, easiest is to hire a driver, particularly as part of a tour; cheaper is to use buses that go to main tourist sites. For access to and from Machu Picchu, rail is the main option (helicopters are possible but very expensive).
If mobility-impaired, you will not be able to engage in more demanding treks such as the Inca trail, but horseback treks are possible, and Machu Picchu itself can be visited. You will need to arrange a private tour; Apumayo expediciones $^{[formerlydeadlink]}$ is the most established and decorated accessible tour operator, offering various itineraries (e.g., Accessible trip to the Inca Land $^{[deadlink]}$).

## Go

A classic visit to the Inca Highlands featuring a trek begins with a flight into Lima, then a flight to Cusco, a few days in the Sacred Valley and Cusco acclimating and seeing sights, then a 4-day trek on the Inca Trail, ending in Machu Picchu, then returning to Cusco, Lima, and home. This takes 8 or more days, which is necessary for travel time and to safely acclimate, but is a bit rushed. Additional time helps: a day or two in Lima on the way in or out, an overnight in Aguas Calientes lets you see Machu Picchu at more leisure, and there are many sights and activities around Cusco and the Sacred Valley. Time also gives a buffer in case of delays, particularly in the rainy season: flights into Cusco may be cancelled, and landslides may close roads.
Numerous alternative treks are also possible, and some end at Machu Picchu, though by a different route. Machu Picchu can also be visited by rail as a day trip from Cusco or overnight, as most visitors do.
Itineraries that omit a multi-day trek can be shorter, more flexible, and are less physically demanding. Including travel, a 5-day trip is possible (Lima, Cusco, Machu Picchu, return) but quite brief for the distance: 6 or 7 days is more satisfying, and can include a day hike in the mountains.

### Lima

Fly into Lima, and spend the night: flights to Cusco largely depart in the morning, to have daylight and to leave time for delays. Start taking ACZ one day before ascent (day of travel or first day in Lima), or two if high-risk.
Consider spending a day in Lima, particularly after a long flight: it's an interesting city, but not your focus.

### Sacred Valley

Fly to Cusco, then on arrival immediately transfer to the Sacred Valley (optional but highly recommended). Take it easy, and enjoy rest and nature. Sleep the night in the valley, acclimating to altitude and enjoying the setting. Following day, see some sights in the valley, then either proceed to Cusco or spend another day in the valley (to acclimate further and see more sights). You can also take day trips to the valley from Cusco.

### Cusco

Cusco is the center of Inca culture: it has much to offer, and is the ideal base for trips to surrounding areas. Take the first day easy, spend at least two nights to acclimate to the altitude, and enjoy the city and surrounds. If you sleep in Cusco for your first night at altitude, you have a high risk of altitude sickness: taking ACZ is encouraged, and you should take it very easy.

### Trek

There are many options for the trek, the focus of this itinerary.

#### Inca Trail

The Inca Trail itself has many variants. Typically you'll take rail or road to the trailhead, starting from km 82 (or km 77 or 88, which require a bit more walking), and then spend 4 days/3 nights on the trail, with an optional extra day and night in Aguas Calientes (5 days/4 nights). There is also a 2 day variant from km 104 that just hikes the end of the trail, through the sun gate.

#### Alternative treks

Alternative treks have much to recommend them: they are less crowded, more unique, more varied (different sights, longer or shorter, more or less demanding), do not require advance reservations, allow pack animals (mules, horses, or llamas), and are significantly cheaper.
The three main alternatives, in increasing order of difficulty, are:
* Lares valley trek from the Sacred Valley, which is lower altitude and easier (flexible, 4 days typical).
    This can end at Ollantaytambo, from which one can continue to Machu Picchu by rail.
* Salkantay trail, via Mount Salkantay (5 days, 75 km, max 4600 meters)
    Same area, but higher and somewhat more demanding than the classic Inca trail. Starts in Mollepata, ends near Machu Picchu at Santa Teresa or Hidroelectrica (the hydroelectric dam), from which one can continue to Machu Picchu by short hike or rail.
* Via Choquequirao (similar site to Machu Picchu, ruins bigger and much, much less touristy) to Machu Picchu (8 days, demanding trail)
    Starts in Cachora, 2 day hike to Choquequirao, then either return, or continue on a long, demanding hike to Machu Picchu, ends at Santa Teresa or Hidroelectrica, like the Salkantay trek.
These treks do not go through the sun gate and descend into Machu Picchu, however: they enter from below, by the town. Other treks simply enjoy the mountains, villages, and wildlife.
There are variants of these, often with idiosyncratic names, or named for a village, mountain, or pass, like "Cachiccata trek", village near Ollantaytambo, basically west/final end of Lares valley trek; and "Ancascocha trek" (variant of Salkantay trek, named for pass).
More distant treks, not in the Machu Picchu area:
* Ausangate trek (5 to 7 days), in mountains east of Cusco (opposite direction from Machu Picchu).

### Machu Picchu

Machu Picchu is the highlight of the trip, though when you arrive, how long you spend, and which side trips you do are variable.
It is possible to return from Machu Picchu the afternoon or evening you arrive, particularly if you arrive early (4 day/3 night trek), but it is more relaxing to spend the late afternoon at the site (after others have left), and the night in Aguas Calientes (5 day/4 night trek). This gives you a rest after the trail, and allows you to see it early the next day, all rested and less crowded.

### Other Inca ruins

Ollantaytambo is the main alternative Inca ruin: it is easily reached from Cusco, it is the end of the Lares valley trek, and it is on the way to Machu Picchu by road or rail, so it can also be seen on the way to or from Machu Picchu.
Choquequirao is similar to Machu Picchu, but much less famous; it is also in the mountains, and can be reached by a trek.

### Other sights

There are numerous other sights in the region.
The Q'eswachaka bridge is the last remaining Inca rope bridge, and is renewed annually in June. It spans the Apurimac River near Huinchiri, in Canas Province, south of Cusco, and is becoming a minor tourist attraction.

### Return

On the way back from Machu Picchu, you can stop at various sites in the Sacred Valley, notably Ollantaytambo; see Ollantaytambo#After_Trekking_to_Machu_Picchu.
Consider spending a day in Cusco or Lima on return: this also leaves a day in case of delay earlier on. However, you've probably seen enough of Cusco while acclimatizing, and ending with Lima is a bit drab: go straight home from Cusco.

## Buy

See Peru#Buy and Cusco#Buy for what and how to buy: the same goods are available throughout this itinerary, with price and quality being the main variables.
Cusco and Lima are the best general places to buy souvenirs, particularly quality ones, like alpaca (buy from reputable vendors to assure quality). Cusco is walkable, so it's a bit easier. Prices in Aguas Calientes and Machu Picchu are higher: buy in Cusco instead. The Pisaq Sunday market is another good option.
On your way out is the easiest time to buy them, so you don't need to haul them around on your trip.

## Stay safe

A key concern is altitude, both acclimatization to altitude and harsh high-altitude conditions, notably strong UV light and dry air. Unless you've already been to Tibet, Bolivia, high Colorado skiing, or high mountain climbing, this is the highest you've ever traveled; it's high, but not extreme.

### Altitude sickness

The most serious issue is altitude sickness: Lima starts at sea level and does not rise high, while Cusco is at high altitude (3,400 m). About 50% of people who fly from Lima and spend that night in Cusco suffer from altitude sickness, sometimes severely. The Inca Trail is higher still, going up to 4,200 m, and sleeping around 3,600 m, while Machu Picchu itself is not very high (~2,400 m), and the Sacred Valley is significantly lower than Cusco, though still at altitude (~2,800 m). The biggest danger is ascending rapidly, and the main solution is to ascend slowly. The main issue is breathing at night, so the altitude at which you sleep is what causes sickness, and conversely helps you acclimate. Thus, flying into Cusco and spending the night there will likely cause sickness, and flying into Cusco and immediately hiking the Inca Trail is idiotic.
To prevent and reduce altitude sickness, fly into Cusco and immediately transfer to the Sacred Valley, which is an ideal altitude to acclimate: spend a night or two there. Proceed to Cusco, spend two nights acclimating, then hike the Inca Trail. There's still a risk of altitude sickness, but less, and milder. Also, take it easy the first days at altitude, and drink a bit more water (an extra liter), and less alcohol (which dehydrates). In case of emergency, descend (drugs and oxygen can help, but descent is the best solution).
For extra safety, you can take acetazolamide (ACZ) before and during ascent, which jump-starts and speeds up acclimatization (it's the same biological mechanism): it's primarily for prevention (prophylaxis), not treatment. You generally need a prescription: check with a doctor. If you take it, expect increased urination (so drink more) and some tingling of the fingers and toes. If you have a history of altitude sickness, or are spending the first night at altitude in Cusco (instead of the Sacred Valley), you certainly should take ACZ, unless contraindicated. If you have no such history and are spending a night or two in the Sacred Valley, it is less necessary, but still prudent. Current CDC guidelines are 125 mg, taken twice a day (every 12 hours), starting the day before ascent, and continuing the first 2 days at altitude, or longer if ascent continues. Per this itinerary, that's day before ascent (in Lima or travel to Peru), then (most prudently) every day at altitude, due to repeated ascents (Cusco, Inca Trail, and low Machu Picchu back to high Cusco). You can discontinue use after highest campsite on trail, as it's descent after that, other than one optional low night in Aguas Calientes. 250 mg is more effective, but side effects are more likely: it's recommended if you are higher risk. If you have enough 125 mg pills, you can double the dose to 250 mg if necessary, so it's prudent to get more than the minimum.
You can also get a pulse oximeter to check your blood oxygen content to see how you're acclimating. Coca (in tea, chewing leaves, or candies) is a mild stimulant, and helps a bit with the symptoms (like coffee for a hangover), but doesn't help you acclimate faster.
On the off chance that you go scuba diving beforehand, wait at least a day before ascending: check with scuba shop.
Altitude sickness is unpredictable: there is no effective screening, and being healthy doesn't protect you; being unhealthy does add to the risk though.

### Other effects of altitude

The sun is strong and the air is dry: wear a broad-brimmed hat, UV-blocking sunglasses, long sleeves, sunscreen (SPF 30+), sun-blocking lip balm, and drink a lot of water. Use moisturizer if you like: the high altitude means water evaporates faster, due to the low pressure. Beware the sun even when cloudy: clouds don't block UV.

### Other concerns

There are also general concerns for Peru (Peru#Stay safe and Peru#Stay healthy), particularly avoiding tap water (use bottled or boiled, even for brushing teeth); and for the Inca Trail itself (Inca Trail#Stay safe), particularly being in shape and equipped, and walking carefully, particularly on slippery wet stone.
Remember that the biggest danger when traveling is road accidents. Notably, have a local driver, and avoid driving at night: if moving locations, do it daytime, particularly morning or midday, not evening.
Since this is in the mountains, not the jungle, there is no need for a yellow fever vaccine. However, if you continue to Amazonia, this is recommended.

## Go next

There are many other destinations in Peru, to extend this trip or for future trips; see Peru#Other destinations and Cusco#Go next. Notable convenient ones include:
* Manú National Park, by tours based in Cusco, 4 to 10 days.
    Access is by a short flight (45 minutes): this is jungle, so yellow fever vaccine is recommended.
* Nazca Lines, either by bus from Cusco, or by bus or plane from Lima; continue on to Lima and home. Takes another day or two.
* Lake Titicaca, based at Puno, either by a short flight (30 minute), a long but spectacular PeruRail train ride (10 hour), or most cheaply by bus.
* Bolivia, starting at La Paz.
    Convenient since already mostly acclimated to altitude, but note that higher parts of La Paz are significantly higher than Cusco!
