The 1138 kilometer long Río Huallaga is a right tributary of the Río Marañón (larger of the two headwaters of the Amazon ) on the eastern slopes of the Andes in northern Peru .
course
In the upper mountainous part, this water and nutrient-rich river flows through the larger cities of Huánuco and Tingo María . The subsequent deeper open valley became known and notorious for the high proportion of coca plantations . Isolated terrorist activities by factions of the Sendero Luminoso , especially in connection with local drug cartels and related activities, make this region (the northern part of the Huánuco region and the southern part of the San Martín region ) unsuitable for tourism, although the landscape along its entire length the course of the river could offer nature experiences. Further to the north, the river, which is becoming wider from various tributaries, meanders through long valleys of the eastern Andean chain, parallel to the Marañón to the west . This region around the larger town of Juanjui is difficult to access because of its deep gorges and raging rivers, but it contains a large number of archaeological sites from various pre-Columbian cultures, especially the Chachapoyas . There are well-known sites in the high elevations of side valleys; the largest, Gran Pajatén , (in the Río Abiseo National Park ), another north of Kuelap , near the watershed between the Marañon and Huallaga rivers.
The Huallaga breaks through the last Andes chains at Chazuta and from then on meanders strongly, past small villages and the city of Yurimaguas , before flowing further north, shortly after Lagunas , into the Marañón .
