Decide what time of year you want to hike the Inca Trail. The trail is closed during February. May through November is the dry season with the most popular months being June through August. During the wet season, showers can be expected three to four days per week. The wet season also sees fewer travelers, and there is the possibility of seeing wildflowers and orchids.
Obtain a passport if you do not have one. U.S. citizens will also receive an entry card from their air carrier, either at the airport or on board their flight.
Decide which company to book your Inca Trail trip with because, as of 2002, it is not possible to hike the trail independently. Companies such as Tucan Travel, Gap Adventures and Inca Trail Reservations will make your reservation and obtain your permit, the Machupicchu Historical Sanctuary Network RED, issued by the Machu Picchu Historical Sanctuary Management Unit. Depending on the company and tour package you choose, they will arrange porters, hotel accommodations and transportation.
Schedule your trip so that you arrive in Cusco or Aguas Calientes a day or two before your trek to give your body a chance to get used to the altitude.
Prepare, physically, for your trip. Look for trails in your area that are hilly, stony and uneven. Hike with a pack containing a water bottle, food and personal items. The pack should weigh 12-14 lbs. Work up to walking 7 hours per day, two days in a row.
