Peru covers 1,285,216 km2 (496,225 sq mi) of western South America. It borders Ecuador and Colombia to the north, Brazil to the east, Bolivia to the southeast, Chile to the south, and the Pacific Ocean to the west.
The Inca Trail is 42 kms (26 miles) long. Campsites along the Trail are assigned by the INC (National Institute of Culture) and for this reason it is difficult to determine the distance to be covered in a day but expect to walk 6 to 9 hours per day for the first three days and approximately 2 hours on the last day.
Peru uses 220 volt, 60 cycle electricity. Travelers will require a voltage converter for 110 volt devices. Plugs are typically the 2 pronged flat type found in the US, though some facilities have been noted to use the 2 rounded prongs instead.
American citizen visitors to Peru do not need a visa if they are traveling as a tourist with a valid U.S. passport. You will be issued a tourist card upon entry, which is valid for up to 90 days. There are no renewals of Peruvian visas.
