The local river-running specialists run rafting trips on the Río Mayo, 30km from Tarapoto, and for those with experience, on the wilder Río Huallaga.

The Río Mayo (half-day trips, from S50 per person) is mostly class II and III, and is more of a sightseeing trip than a full-on adventure. Kayaks are available for rent with mandatory guide (half day S100).

Try safety-first Ecorutas whose owner, Julio, speaks a bit of English; or Kuriyacu, which can arrange guides in English and French.
