I am traveling to the areas as part of a spate tour. I am interested in seeing the Amazon, however, travel to Iquitos will require a full day of transfers and air travel, long boat ride, etc. however, you get to see the actual Amazon River. If we go to the amazon jungle by way of Puerto Maldonado, we see only a small tributary, but a more inclusive jungle experience. Which is better? we are only doing a 3-4 day trip.
