Mayo River, San Martin
This is a well-loved, half-day excursion from Tarapoto.
The entry point is at the small riverside village of Churuyacu, a 45-minute drive along the main road towards Moyobamba.
The rapids are Level II - III year round, so good for beginners, and it is also deep enough at a couple of points to jump out of the boat and float downstream.
The scenery in the valley is beautiful, being a mix of high jungle and agricultural land, with plenty of birdlife in evidence.
15 minutes from the exit point - the village of Maceda - there is a riverside beach, where there is a rope swing (‘soga de Tarzan’) into the river, tied to an overhanging tree, and a couple of swings (also hanging from trees).
