I was on the Tambopata River, a tributary of the Amazon River. Of course it's not specifically on this map but it is off the Madre de Dios in southern Peru.
We were down river from Puerto Maldonado, which is where we flew into. You can see on this map the location of Cuzco (close to Machu Picchu), Puerto Maldonado and the Brazilian border
Rainforest Expeditions has three lodges and we stayed at Refugio Amazonas.
The trail map at Refugio Amazonas. I certainly hope this isn't to scale because it seemed like the canopy tower was very close and the non-parrot clay lick was much further away.
