These remarkable ruins became known to the scientific world in 1911, after the American archaeologist Hiram Bingham was led to the site by locals. Perched dramatically 1000 ft above the Urubamba river, Machu Picchu is a UNESCO World Heritage site. It is also the end point of the most popular hike in South America, the Inca Trail.
The story of Machu Picchu is quite a remarkable one; it is still unknown exactly what the site was in terms of its place in Inca life. Current researchers tend to believe that Machu Picchu was a country resort for elite Incas. At any given time, there were no more than 750 people living at Machu Picchu, with far fewer than that during the rainy season. The Incas started building it around 1430AD, but it was abandoned as an official site for the Inca rulers a hundred years later at the time of the Spanish conquest of the Inca Empire.
One thing that is clear is that it was a remarkably well hidden place, and well protected. Located far up in the mountains of Peru, visitors had to travel up long valleys littered with Inca check points and watch towers. Remarkably, the Spanish conquistadors missed the site. However, many people are said to have knowledge of the ancient city as it was referred to in some text found in the 20th century; even so, it was not until Bingham that Machu Picchu was scientifically discovered (he was on a trip sponsored by the Yale University, actually looking for Vilacamba, the last Inca hideout).
Machu Picchu was declared a Peruvian Historical Sanctuary in 1981 and a UNESCO World Heritage Site in 1983. Since it was not plundered by the Spanish when they conquered the Incas, it is especially important as a cultural site and is considered a sacred place.
Machu Picchu was built in the classical Inca style, with polished dry-stone walls. Its primary buildings are the Intihuatana, the Temple of the Sun, and the Room of the Three Windows. These are located in what is known by archaeologists as the Sacred District of Machu Picchu. In September 2007, Peru and Yale University reached an agreement regarding the return of artifacts which Hiram Bingham had removed from Machu Picchu in the early twentieth century.
 Flora and fauna
Both are abundant and varied. Typical plant life in the historic reserve of Machu Picchu includes pisonayes, q'eofias, alisos, puya palm trees, ferns and more than 90 species of orchids.
The fauna in the reserve includes the spectacled bear, cock-of-the-rocks or "tunqui", tankas, wildcats and an impressive variety of butterflies and insects unique in the region.
The lay of the land, the natural surroundings and the strategic location of Machu Picchu lend this monument a fusion of beauty, harmony and balance between the work of the ancient Peruvians and the whims of nature.
 Get in
There are a few ways to reach Machu Picchu:
- hike the Inca Trail (you need to book months in advance in high season and you cannot go independently)
- There are tour operator agencies to organise an adrenaline trip to Machu Picchu: biking, rafting, hiking and zip lining. This is usually marketed as the Inka Jungle trek to Machu Picchu.
- train from Cuzco or Ollantaytambo, either on a day trip, or overnighting in Aguas Calientes. Overnighting allows you to visit the park early or late in the day and avoid the worst of the crowds, and on sunny days, gives you a nice window of reprieve from the beating sun. Don't forget sunblock. Train tickets are probably the most expensive in the world (by distance). A one way ticket from Ollantaytambo will set you back USD55-80 and from Cuzco even more. There is a luxurious service that can cost as much as USD700. Peru Rail (Cusco or Ollantaytambo to Aguas Calientes) is a concession run by foreign investors, so much of the money does not stay in Peru. (Some people take this into account when they choose their way to get to Machu Picchu.) Inca Rail (Ollantaytambo to Aguas Calientes) is a concession run by Peruvian investors. Advance train bookings are recommended, as trains are often sold-out, particularly return trains.
- minibus to Hidroelectrica through Santa Maria and Santa Teresa (altogether around PEN40 one way, allow 6-7 hours, you might have to change in Santa Maria and/or Santa Teresa). Then you can walk along the railway from Hidroelectrica to Aguas Calientes (free, 2.5-3h) or take the train (15-18 USD one way). If you go for this option, ask around agencies in Cuzco as it might be cheaper to buy a package that includes the trains to and from Hidroelectrica, buses from Aguas Calientes to MP, minibuses between Hidroelectrica and Cuzco, accommodation in Aguas Calientes and the ticket to MP. The package might be cheaper than going independently, although you will be less flexible once you buy the package.
The wet season in Peru is from November (often only really taking off in December) until the end of March, so then it is best to include a few extra days for flexibly dealing with delays.
From Aguas Calientes, there are two ways to reach the ruins: by bus (18 USD for a return ticket, with each leg taking 20 minutes) or walking (free steep hike), as described below.
Depending on when you arrive, the site may be quite crowded or nearly deserted. The busiest periods are in the dry season (June-August), with the slowest being in February, the height of the rainy season, when the Inca Trail is closed. Most visitors arrive on package tours and are in the park between 10:00 and 14:00. All visitors must leave Machu Picchu by 17:00
To access the site, you must have a ticket for Machu Picchu - which are available on in advance from machupicchu.gob.pe or from various ticket offices described on that website, including one across from the town hall in Aguas Calientes. Machu Picchu tickets are NOT sold at the entrance gate and are limited to 2500 per day, with entrance to Huayna Picchu and Montana Machu Picchu each being further sublimited to 400. During peak times of the year, tickets can sell out days in advance.
 By bus from Aguas Calientes
If arriving by train into Aguas Calientes, walk out of the station and keep going roughly straight through the warren of handicraft stalls and over a foot bridge to the bus departure area. Frequent buses leave to the ruins (USD10 one way or USD19 for a pair of one way tickets), for adult foreigners) starting at 05:30. There's often a queue, so if you're intent on being on the first bus up, you should arrive at least 90 minutes early. The journey takes around 1/2 hour to slowly wind around the switchbacks and up to the park. Buses depart when full, which typically means they run quite regularly. At popular times, there may be a lengthy queue for the busses and a lengthy queue to buy bus tickets, so plan the return trip accordingly in order not to miss train departures.
 By foot from Aguas Calientes
From Aguas Calientes to get to the ruins themselves it is also possible to walk along a similar 8 km route that the buses run, which will take about 1-2 hours up, and around an hour back down. This route is mainly stairs, connecting the switchbacks that the buses take. It is a strenuous and long hike but is very rewarding, recommended to start around 05:00 when the gate at the bridge opens (it takes around 20 minutes to walk from Aguas Calientes to the bridge (where a checkpoint is in place to verify that hikers already have entrance tickets), so there is little use in starting from Aguas Calientes earlier than 04.40), to make it to the top before sunrise. The descent is fairly easy, just take care when the steps are wet. Keep alert for the bus drivers that rarely brake for pedestrians.
 By foot via the Inca Trail
Hiking the Inca Trail is a great way to arrive as you first see the city through the Sun Gate (instead of arriving from below as you do from Aguas Calientes). Both the four-day and two-day hikes are controlled by the government. Travellers should be fit enough to walk for days and sleep in tents. Every traveller needs to travel with a tour agency because of the rules and regulations of entering the park. Some of these approved tour agencies: Tierras Vivas, Cusi Travel and Llama Path.
There are also other options available for hiking to Machu Picchu. This is important to know as the Inca Trail hike is limited to the amount of people that can go on it each day, including porters. As such, there is a much steeper price on this trek and it is necessary to book far in advance to get a place on the dates you will be there.
The Salkantay trek is a 4-5 day trek through the Salkantay Mountain Pass (4600 masl, mind the altitude!) and can also be done independently if you have the gear and some experience. The scenery is amazing and if you go in the rainy season you will be rewarded with dozens of waterfalls. Though, at the same time, you will be wet for the most part anyways.
The other option, Inka Jungle trek to Machu Picchu is an alternative and adrenaline hike to Machu Picchu.
Other alternative trip to Machu Picchu is by car, but the "backdoor" route they use is also an option for independent travellers wishing to go-it-alone. Minivans and buses are cheap (15-30 soles) from "Terminal Santiago" in Cusco and take you to either Santa Maria or Santa Teresa. Santa Maria is further away from Aguas Calientes than Santa Teresa but is a nice option for those wishing to hike an alternative Inca trail used locally. The walk takes you through the mountains and tiny villages, even people's farms and offers impressive views of the valley. You can end up in Santa Teresa the same day and there are villages, such as Huacayupana and Quellomayo en route which offer an alternative view of local life and accommodation if you don't make it to Santa Teresa that day. Walking on from here to Santa Teresa is along the river (May - November) and by road during rainy season, although it is advisable to get advice before taking this route between November and April due to severe weather, but be very careful. From Santa Teresa to Hidroelectrica is a 25 minute taxi or minibus ride and from here you can walk 3 hour flattish trek to Aguas Calientes which is one of the nicest parts of the journey.
The Peruvian government has imposed a 500 person pass limit per day on Inca Trail traffic. Passes do sell out far in advance, particularly for the high season. Travelers must have a valid passport in order to purchase a pass at the time of reservation. Many local tour operators have since opened up alternate trekking options that allow for similar trekking opportunities in the area. Most visit other Inca ruins, not as well excavated, and finish with the train trip up to see Machu Picchu at the end. One such option is the Choquequirao Trek, which starts in Cacharo and ends in Los Loros or the Cachiccata Trek which starts in Racca and ends in Cachiccata.
The current fee schedule and online tickets are available at the official government website and from ticket offices listed on that website. As of Feb 2014, the entrance fee is PEN126, with discounts for children and students with an ISIC card.
There are three types of tickets: (1) only entrance to MP, (2) MP + climbing Huayna Picchu, (3) MP + climbing Cerro Machu Picchu (aka Montaña). The number of visitors climbing each of the hills is restricted to 400 a day. Huayna Picchu is not as high and easier and therefore more popular. Tickets for it might sell out more than a week in advance. Montaña is higher and more difficult, but the views are actually better. Tickets for it sometimes sell out. You can check the availability for any, at any time on the website.
When preparing your budget, do not forget to include train tickets and bus tickets. Food at the site is USD36 for a lunch buffet. Officially, you are not allowed to bring food inside, but no one checks backpacks. If you bring it in a transparent plastic bag, they will ask you to store it at the entrance. Officially, disposable plastic bottles are not allowed either, but no one seems to care about this. Again, it is best to carry everything in the backpack. In the rush at the entrance they don't have time to check everyone.
Students get a 50% discount of all entrance tickets. Your best bet is to show an ISIC card. They sometimes also will accept your university card, although if you are above 25 years of age, they will insist on the ISIC card, although there is no regulation about that whatsoever. You can try to argue but good luck! - the staff, especially at the ticket office in Aguas Calientes, can be quite arrogant and they really want your money anyway.
Most hostels can sell entry permits and bus tickets. Don´t buy them at the travel agency at the Ollantytambo train station, as they don´t actually sell you tickets, but a receipt that you need to give to a person to get your tickets, you´ll end up running all around Aguas Calientes looking for this person. You can buy your ticket at the Aguas Calientes cultural centre. 05:30-21:00.
Be sure to bring your passport, as it is requested upon entry. There's a popular stamp booth as you exit where you can prove to your friends you've been there, although it is technically illegal for the citizens of many countries to mark their own passports.
Only small packs are allowed in the park (no more than 20L), but there is a luggage storage at the entrance mostly used by Inca Trailers.
Only 2,500 people are allowed to enter Machu Picchu each day. The government website (http://www.machupicchu.gob.pe/) lists how many tickets are available for each day. Also, visitors must purchase tickets for Huayna Picchu in advance and there is now an additional fee to hike Huayna Picchu (as of Feb 2014 the entrance fee for Huayna Picchu and Machu Picchu was PEN150).
 Get around
There are no vehicles of any kind in the park, bring some comfortable walking shoes, especially if you plan to do any of the hikes such as Wayna Picchu. No walking sticks are allowed. The main ruins are fairly compact and easily walkable.
[add listing] See
Take your time walking around the site, as there are many places to see and explore. Although it is not necessary, taking a guided tour does provide a deeper insight into the ancient city, its uses, and information on the geography of it. Keep in mind that relatively little is known about the history and use of the ruins, and some of the stories told by the guides are based on little more than imaginative hearsay. Guides always wait at the entrance and cost PEN120 for a group.
[add listing] Do
If you have some energy in you, there are a few great hikes involving a bit of legwork. Do make sure that you've taken the time to acclimate to the elevation either in Cuzco or Aguas Calientes for a couple days before exerting yourself too much, especially on Wayna Picchu.
[add listing] Eat
Officially, you are not allowed to bring any food or water bottles into the park, and must check these in at the luggage storage at the entrance. In practice, however, bags are rarely searched, and most people have no problem getting a small bottle of water and some snacks in with them, which you'll definitely want, especially if you're planning to stray from the central set of ruins. Buy these beforehand, as they're much more expensive at the site itself. Don't even think of leaving a shred of trash behind you.
The concession stand near the entrance of the site is appropriately overpriced given their captive audience. Once in the site, there are no food or drinks for sale, though it is possible to leave and return.
[add listing] Sleep
Due to the fact that this is a protected park, further construction in the area is nearly impossible. Thus, there is currently only one expensive hotel at the site itself. Almost everyone who wants to stay overnight near Machu Picchu books a hotel in nearby Aguas Calientes.
Machu Picchu is a world heritage site, very popular, very well marketed and indeed situated in a place of exceptional natural beauty. This is where the good news end. On the other hand, it can be extremely expensive to visit (most of the time you will be treated as a walking ATM), it can be very crowded, very touristy, much of the staff around the site and in Aguas Calientes look like it's a long time since they last smiled and they can be very arrogant. Many people therefore choose not to visit. Below are some alternatives. If you are interested in Inca ruins, try those around Cuzco, Ollantaytambo and the excellent Choquequirao. If you still go to Aguas Calientes, but decide not to pay for the entrance to Machu Picchu, you can climb Cerro Putukusi (highly recommended even if you visit MP) , right next to Aguas Calientes (1-2h up, 1h down) to get fantastic views of the site and the surrounding nature. Also, the branch of the Salkantay Trek that ends in Hidroelectrica, has good views of MP from further away and some ruins, where you can camp and enjoy the view to MP.
