The Amazon region is also called the lung of the world, not without a reason. The entire Amazon basin covers 7 million square km, of which 400.000 square km are on Colombian territory. Leticia, a hospitable and enchanting city, is located in the border triangle of Brazil, Peru and Colombia. It is surrounded by walkways into the jungle, like to the Tanimboca reserve with its canopy-shaped trees. Jungle paths lead to the villages of the indigenous tribes, like the Palmeras, a little and rather seldom visited community of the Tikuna tribe. Another path, which runs parallel to the Amazon river, leads to San Martín de Amacayacu. It is a two-hour walk and there you have the possibility to observe several wild- and bird life. They also offer workshops for basket-weaving, weaving and wood-cutting.
