Mist rises off the river as your guide leads a small group under low-hanging Cecropia and fig trees; the forest breathes slowly here, and time seems to match the pace of the creatures you came to see. On a 1.5 km (1 mi) trail along a ribbon of river, the sloth’s deliberate movements are the main event—especially on an evening walk when two-toed sloths become more active.
