The “Pipeline Trail”, as the trail is named, is not necessarily a very pretty one. The trail was built for the construction of a pipe and, as the plan was conceived, was to be paved for 18 kilometers through the jungle, but it never got that far. After World War II broke out, the construction project was halted only to never be finished. Fortunately, the road now serves as a walking trail through the national park and with a width of two meters it is perfectly suited to search for the more than 500 animal species that live in this park of which we were able to see some. We spotted several trogons and Motmots, Toucans, Hummingbirds and two agouti. The loud screeching of the Southern Mealy Parrots (Mülleramazone) was answered by several Howler Monkeys which, although we did not get to see them, were hiding loud and clear high in the trees. It was a successful hike.
