The main entry point to the Chalalán Ecolodge (Bolivian Amazon) is the town of  Rurrenabaque, which can be accessed by air or land from the city of La Paz. By air the trip takes approximately 50 minutes, by land around 18 hours.
From Rurrenabaque to Chalalán, the Ecolodge is accessed by boat up the rivers Beni and Tuíchi by motorboat – 5½ hours.
