The main river is navigable for large ocean steamers to Manaus, 1,500km (930mi) upriver from the mouth. Smaller ocean vessels below 9000 tons and with less than 5.5m (18ft) draft can reach as far as Iquitos, Peru, 3,600km (2,200mi) from the sea. Smaller riverboats can reach 780km (480mi) higher, as far as Achual Point. Beyond that, small boats frequently ascend to the Pongo de Manseriche, just above Achual Point in Peru. [60] Today, we head to the Tijuca Forest National Park, one of the largest urban forests in the world, and a rare strand of Atlantic rainforest which is now nearly extinct. The trip is done partly in a 4 x 4 vehicle and partly on foot. There are two ways of entering the park and we opt for the less well-known route as the better views can be found on this road. Our first stop is at a lookout known as the Vista Chinese due to the oriental-styled pagoda-like gazebo. From here we get spectacular panoramic views of the south of Rio de Janeiro before rejoining the more well-trodden path and arrive at the second entrance to the park.

The length measurements of many rivers are only approximations and differ from each other because there are many factors that determine the calculated river length, such as the position of the geographical source and the mouth, the scale of measurement, and the length measuring techniques (for details see also List of rivers by length).
