The Amazon is the obvious place to move on to from Huánuco and the surrounding area, unless you’re heading back to Lima and the coast. The spiralling descent north is stunning, with views across the jungle, as thrilling as if from a small plane. By the time the bus reaches the town of Tingo María, a possible stopover en route to Pucallpa, the Río Huallaga has become a broad tropical river, navigable downstream in shallow canoes or by balsa raft. And the tropical atmosphere, in the shadow of the forested ridges and limestone crags of the Bella Durmiente mountain, is delightful. From Tingo María you can continue the 260km directly northeast on the dirt road through virgin forest, going through the Pass of Padre Abad, with its glorious waterfalls, along the way to Pucallpa, jumping-off point for expeditions deep into the seemingly limitless wilderness of tropical jungle.
