Tambopata Research Center requires at least four nights because of the travel time. One consecutive afternoon and morning are spent on the way to and from the lodge, so unless you plan on spending at least two nights at TRC, the hours in the boat are not worth it. However, TRC is the ideal option for in depth explorations of the rain forest lasting four or more nights because: . The seven hour upriver drive takes you 150 kilometers into the uninhabited heart of the Tambopata National Reserve, where the surrounding wilderness is untouched. The largest known macaw clay lick is five hundred yards from the lodge. Dusky headed titi, squirrel, brown capuchin, howler and spider monkeys, as well as capybara, caiman, and agouti are seen frequently. Although very difficult to see, herds of peccary, tapir and jaguar are all at their carrying capacity. . Two state of the art, long term research projects are based out of TRC: the macaw project and the areas project (see Conservation Impact Sheets). . The combination with Refugio Amazonas allows you to experience the canopy tower and the oxbow lake.
