Misahuallí’s most enjoyable sight is some way outside the town, but it’s well worth spending a few hours to do the return riverside walk, which takes you through the rainforest. Take a Misahuallí–Puerto Napo bus and ask the driver to drop you at Río Latas, about 15 or 20 minutes from Misahuallí. All the drivers know el camino a las cascadas (the trail to the falls). Follow the river upstream to the falls, which takes an hour, passing several swimming holes en route. Be prepared to wade.
