On this first full day of expedition, we walked through the forest. We started by walking next to the river to look for kingfisher nests. We arrived at the forest entrance and started hiking. On our walk, we found numerous plant species that are unique to this area, such as the curare liana and the copal tree.

In the afternoon, pink dolphins welcomed us by swimming around the boat. We went kayaking to explore a tributary of the Marañon River.
