Eco-friendly PUERTO NARIÑO sits around 75km upstream of Leticia and makes a great base for spotting the Amazon’s pink dolphins; half-day excursions to Lago Tarapoto cost around COP$55,000 for up to three people. You can learn more about the endangered creatures at the riverfront Fundación Omacha (omacha.org), located right near the docks. The village itself, peopled mostly by the indigenous Yagua, Tikuna and Cocoma, is a shining example of recycling, organic waste management and rainwater collection; other Colombian towns could learn a great deal here, and this may well be the only Colombian settlement with zero motorized traffic.
