Not a hotel with a trail behind it
Yanayacu is a working biological station in temperate cloud forest on the east Andean slope, at km 5 of the Las Caucheras road in Cosanga. Researchers have worked here for 21 years, and visitors sleep in the same place they do.
That is what makes the birding different: the trails, the feeders and the observation points exist because someone needed them for fieldwork, not because they photograph well.
