One has to take into account that the Peruvian Rain Forest has a very varied climate, which is often related to its altitude above the sea level. There are two basic types of Rain Forest in Peru. The High or Cloud Forest and the Low Forest.

The High Forest or Cloud Forest is characterised by its very uneven terrain and sometimes high elevations. It is normally very humid and there is thus often a low ground fog that makes it difficult to determine your position by the sun. Its flora and wildlife is totally different from the Low Forest.

The Low Forest is generally very humid; in those places where there are no major hills and the terrain is low; one will find swamps and mud, the so called "aguajal", almost impossible to cross on foot. The forest or shrub land itself is very dense, and very difficult to enter and thus even more difficult to determine your position due to the density of the vegetation.
