After lunch we headed down river for 25 minutes going past an island in the middle. The river is about 500-700 metres wide and the soft bank sediments are constantly being eroded.
We were heading for the original Eco lodge which was established on a small scale in the mid 1970s. Until relatively recently there were just four such lodges, now there are 25.
We were headed for an aerial walkway 27 metres up in the air - at the canopy level. 80% of solar radiation is absorbed by the canopy and only 5% reaches the ground. Many small animals live in the canopy where they can avoid their predators.
The walkway has been in place for 11 years and the two towers are 30 metres above the ground at either end and the planks are made of "iron" wood - Shihuahuaco.
Our guide reassured us that it should last 20-25 years and bits are regularly replaced.
