Surprisingly, Gocta, a 771 meter (2,529 feet) waterfall, believed to be the third tallest in the world, wasn't brought to the attention of the Peruvian government until 2006. The falls, about 50 km (31 miles) are strongest during the rainy season, from November to April, though during the dry season the sun will likely be out and you will be able to swim at the base of the falls. Occasionally, on the 2.5 hour hike from Cocachimba (you can hire guides there if you are not
coming on a tour from Chachapoyas) you may be able to spot toucans or the endemic yellow tailed wooly monkey. The best way to appreciate the falls is by staying at the charming, 10-room Gocta Lodge (042/526-694, www.goctalodge.com), especially if you prefer the light of the morning or afternoon.
