Get picked up from your hotel in Foz do Iguaçu and drive to Echaporã Port. There, embark on a boat journey on the Kattamaram II, a safe and comfortable boat with A/C, a full bar, and kitchen. Over a delicious dinner onboard, contemplate the meeting between the Iguaçu and Paraná Rivers, which make up the border between Brazil, Argentina, and Paraguay.  Continue down the Paraná River to the Three Frontier Landmark. Pass under the Tancredo Neves Bridge, also known as Fraternity Bridge or the Friendship Bridge. All the while, you'll be gliding along the gorgeous Iguaçu River — the border between Brazil and Argentina. Cruise up to the rushing Tamanduá River, docking there for a few minutes so you can take a dip in a jetty with a swimming pool, exclusive use of the catamaran's passengers. Return to the port and transfer back to your hotel in Foz de Iguaçu.
