Along the amazon on a boat like in the famous movie "Fitzcarraldo". Somehow I pictured myself on a wooden boat like that. In the end I've chose the luxurious version: 12 hours from Leticia/ Colombia to Iquitos/ Peru in a speed boat. Like a luxury bus - just on the river. At 3:30 am I waited on a runway surrounded by the dark with others for a water taxi that broad us from the colombian/ brasilian side over the river to Peru. The day before I had to get an exit stamp in my passport from Colombia and an entry stamp into Peru. Bureau-cracy! The boat ride in the end was quite comfortable. And during the journey we passed two (!) other slow boats. Those ones are more Fitzcarraldo style. Heavy wooden boats where the locals sleep in a hammock on the first floor and below are cows, pigs and all kinds of products. Sounds more fun but better with a group...After 12 hours we reached Iquitos/ Peru. A poorer version of Leticia. After on night I left the tropical climate towards Lima. And after an eight hours stopover there I continued to the Inca capital of Cusco - high up in the mountains with finally fresh air but lower temperatures!
