At its most basic, the Inca Trail (Camino del Inca) was a footpath through the Andes leading directly to the gates of Machu Picchu. Contrary to its image as a lone, lost, remote city, Machu Picchu was not isolated in the clouds. It was the crown of an entire Inca province, as ruins all along the Inca Trail attest. Machu Picchu was an administrative center in addition to its other putative purposes. That larger purpose is comprehensible only to those who hike the ancient royal route and visit the other ruins scattered along the way to the sacred city.
More than that, though, the Incas conceived of Machu Picchu and the great trail leading to it in grand artistic and spiritual terms. Hiking the Inca Trail -- the ancient royal highway -- is, hands down, the most authentic and scenic way to visit Machu Picchu and get a clear grasp of the Incas' overarching architectural concept and supreme regard for nature. As impressive as Machu Picchu itself, the trail traverses a 325-sq.-km (125-sq.-mile) national park designated as the Machu Picchu Historical Sanctuary. The entire zone is replete with extraordinary natural and man-made sights: Inca ruins, exotic vegetation and animals, and dazzling mountain and cloud-forest vistas.
Today the Inca Trail -- which, as part of the Machu Picchu Historical Sanctuary, has been designated a World Heritage natural and cultural site -- is the most important and most popular hiking trail in South America, followed by many thousands of ecotourists and modern-day pilgrims in the past 3 decades. Its extreme popularity in recent years -- more than 75,000 people a year hike the famous trail -- has led to concerns among environmentalists and historians that the trail is suffering potentially irreparable degradation. The National Institute of Culture (INC) and the Ministry of Industry, Tourism, Integration, and International Trade (MITINCI), reacting to pressure from groups such as UNESCO (which threatened to rescind Machu Picchu's World Heritage Site status), instituted far-reaching changes in practices designed to limit the number of visitors and damage to Machu Picchu and the Inca Trail, though these alone may not be enough to forestall the trail's damage.
There are two principal ways to walk to Machu Picchu: either along the traditional, fairly arduous 4-day/3-night path with three serious mountain passes, or as part of a more accessible 2-day/1-night trail (there's also an even shorter 1-day trek that covers just the last part of the trail, which is suitable for inexperienced walkers). You can hire porters to haul your packs or suck it up and do it the hard way. Independent trekking on the Inca Trail without an official guide has been prohibited since 2001. You must go as part of an organized group arranged by an officially sanctioned tour agency (At the end of 2011, 188 agencies, both in Cusco and beyond, were allowed to sell Inca Trail packages). A couple or a small number of people can organize their own group if they are willing to pay higher prices for the luxury of not having to join an ad-hoc group.
Sadly, even with the new regulations, hiking the Inca Trail, beautiful and mystical as it remains for most, is not a silent, solitary walk in the clouds. At least in high season, you will contend with groups walking the trail both in front of and behind you, and some will invariably be noisy student groups.
Preparing for Your Trek
The classic 4-day route is along hand-hewn stone stairs and trails through sumptuous mountain scenery and amazing cloud forest, past rushing rivers and dozens of Inca ruins. The zone is inhabited by rare orchids, 419 species of birds, and even the indigenous spectacled bear. The trek begins at Qorihuayrachina near Ollantaytambo -- more easily described as Km 88 of the railway from Cusco to Aguas Calientes. The 43km (26-mile) route passes three formidable mountain passes, including the punishing "Dead Woman's Pass," to a maximum altitude of 4,200m (13,800 ft.). Most groups enter the ruins of Machu Picchu at sunrise on the fourth day, although others, whose members are less keen on rising at 3:30am to do it, trickle in throughout the morning.
The 2-day version of the trail is being promoted by authorities as the Camino Sagrado del Inca, or "Sacred Trail," although it might also be called the Camino "Lite." It is a reasonable alternative to the classic trail if time or fitness is lacking. The path rises only to an elevation of about 2,750m (9,020 ft.) and is a relatively easy climb to Huiñay Huayna and then down to Machu Picchu. The minitrail begins only 14km (8 3/4 miles) away from Machu Picchu, at Km 104, and it circumvents much of the finest mountain scenery and ruins. Groups spend the night near the ruins of Huiñay Huayna before arriving at Machu Picchu for sunrise on the second day. More and more people of all ages and athletic abilities are tackling the Inca Trail; the Peruvian government, in addition to adopting more stringent regulations governing its use, also placed flush toilets in campsites several years ago in an attempt to make the trail cleaner and more user-friendly.
Either way you go, it is advisable to give yourself a couple of days in Cusco or a spot in the Sacred Valley to acclimatize to the high elevation. Cold- and wet-weather technical gear, a solid backpack, and comfortable, sturdy, broken-in (and waterproof) hiking boots are musts (also needed: sleeping bag, flashlight/headlamp, and sun block). Above all, respect the ancient trail and its environment. Whatever you pack in, you must also pack out. You should also choose your dates carefully. The dry season (June-Oct) is the most crowded time on the trail, but it's excellent in terms of weather. Shoulder seasons can be best of all, even with the threat of a bit of rain; May is perhaps best, with good weather and low numbers of trekkers. Other months -- especially December through March -- are simply too wet for all but the hardest-core trail vets. The entire trail is now closed for maintenance and conservation during the month of February -- which was one of the rainiest and least appealing months for trekking to Machu Picchu anyway. For the most popular months (May-Sept), early booking (at least 3 months in advance) is essential.
The Peruvian government has sought to limit the number of trekkers on the Inca Trail (now capped at 200 trekkers or 500 total, including trek staff, per day), but also to maximize revenue from one of its foremost attractions. Thus, the cost of hiking the trail has steadily climbed -- it now costs at least three times what it did just a few years ago. Standard-class 4-day treks, the most common and economical service, start at about $450 per person, including entrance fees ($88 adults, $44 students) and return by tourist trail. Independent trekkers generally join a mixed group of travelers; groups tend to be between 12 and 16 people, with guaranteed daily departures. The cost includes a bus to Km 88 to begin the trek, an English-speaking guide, tents, mattresses, three daily meals, and porters who carry all common equipment. Tips for porters or guides are extra. Personal porters, to carry your personal items, can be hired for about $130 for the 4 days. Premium-class services generally operate smaller group sizes (a maximum of 10 trekkers), and you generally get an upgrade on the return train. Prices for premium group treks, organized for private groups, range from $750 to as high as $1,000 per person.
Prices vary for trail packages based on services and the quality and experience of the agency. In general, you get what you pay for. Rock-bottom prices will probably get you an inexperienced guide who speaks little English, food that is barely edible, camping equipment on its last legs, and a large, rowdy group (usually 16 young trekkers). Especially important is the ability of an agency to guarantee departure even if its desired target number of travelers is not filled.
Never purchase Inca Trail (or, for that matter, any tour) packages from anyone other than officially licensed agencies, and be careful to make payments (and get official receipts) at the physical offices of the agencies. If you have questions about whether an agency is legitimate or is authorized to sell Inca Trail packages, ask for assistance at the main tourism information office in Cusco.
To guarantee a spot with an agency (which must request a trek permit for each trekker) it is imperative that you make a reservation and pay for your entrance fee a minimum of 15 days in advance (though in practice you'd be wise to do this at least 4-6 months or more in advance if you plan to go during peak months of May-Oct). Reservations can be made as much as a year in advance. Gone are the days when trekkers could simply show up in Cusco and organize a trek on the fly. Changing dates once you have a reservation is difficult, if not impossible. If spots remain on agency rosters, they are offered on a first-come, first-served basis.
The entrance ticket for the 2-day Camino Sagrado, purchased in Cusco, is $51 for adults and $44 for students. Basic pooled service (maximum 16 trekkers) costs about $200 to $250 per person (including the entrance fee).
