The first day of our adventure began quite early. We set out to explore a very picturesque and tidal-dependent river called Agujitas. The river is named for the abundant needlefishes that call it home. Aguja is the Spanish word for needle. We saw various shorebirds, a two-toed sloth, iguanas, and basilisks, or Jesus Christ lizards. Right after lunch, we repositioned our vessel and took various hikes and walks along Caletas Beach. Long walks, forest treks, and nature walks gave us the chance to explore the area and take great photographs.
