It is an hour by plane from Lima, in the high jungle plateau to the east of what is known as the selva baja. Although Moyobamba is the capital of the region, Tarapoto is the region's largest city and is linked to the Upper Amazon and the historic city of Yurimaguas by a relatively well-maintained transandean highway, paved in 2008–9.
