Just returned from a fantastic trip which involved traveling from the US to Lima, to Iquitos and then meeting our guide, Gary Lighthall and his crew to take the most amazing trip (firstname.lastname@example.org)
Gary picked us up at the La Casa Fitzcarraldo and we drove 1 1/2 hours to Naulta where we caught the rapid launcha to Ollanta. Overnight in Ollanta where Gary's crew and two long boats were waiting.
It took another full day and 1/2 to reach the first of the Urarina villages but it was so worth it. Gary bought items to trade with the people and trade they did! They wanted batteries, fabrics, flashlights, shotgun shells, beads, knives etc and they traded handmade crafts such as baskets, weavings. We stayed in school houses/community centers (a tented city) so that we would be out of the rain. Rained just a couple of times as it was low water season.
We were able to observe (and take photos) of the daily lives of these incredible people. These were not tourist areas and they had no idea that we were coming. Gary has done this type of adventure travel for over 10 years. The Urarinas love it when he comes so that they can trade for the useful items they need.
I would HIGHLY recommend this trip for those who are in good health, good shape and want something more than a well traveled road. Each day was a new adventure and a wonderful leaning experience. If you want to know more, contact Gary (or me via Trip Advisor). It is one of those trips of a lifetime:-)
