Approximately 130km upriver from Iquitos on the Rio Yarapa, this lodge is simply stunning. It has a huge and well-designed tropical biology laboratory, regularly used by the US Cornell University for research and postgraduate classes. The lab is powered by an expansive solar-panel system, which also provides electric power throughout the lodge (bring your laptop). The lodge has satellite phone connections. The facilities are beautifully maintained, with an impressive entrance pier, elaborate wood carvings in the restaurant/bar and even on the bed-heads, and fully screened rooms linked by screened walkways. Eight huge bedrooms with oversized private bathroom are available (professors stay here when Cornell is in residence) and 16 comfortable rooms share a multitude of well-equipped, modern bathrooms. Of course, with its scientific agenda, the lodge offers top-notch guides for its jungle tours, which visit remote areas. Their boats take about three to four hours from Iquitos but have a bathroom aboard. Recommended.
