We had only 10 hours to visit Leticia and its vicinity and Tomas put together a  very comprehensive tour that allowed us to experience and truly enjoy the 'Tres Fronteras' area. As a native of the region, he is very knowledgeable and experienced in all things Amazon, its flora, fauna, tradicional medicine and he is also very friendly and patient. We had the opportunity to walk the streets of Leticia, Tabatinga on the Brazilian side, and sailed the Amazon River to have lunch in Santa Rosa, on the Peruvian side. Also did Pink Dolphin watching and tried the famous brazilian cokctails known as Caipirinhas. Overall and amazing and unforgettable experience. Will recommend Tomas 100%.
