This is the only way to go uo to the Wasai's river lodge. You need to be able to take just a small carry bag and then leave your large backpack etc at the main lodge.
As you leave the town environs the scenerery changes giving way to farmlands and then gradually becoming increasingly forested. As we were going to one of the furthest lodges along the river we passed most of the other lodges along the way.
Once you reach the Bio-sphere's border there is a check point where you need to sign in. On came the gumboots and a very slippery walk up to the top through all that lovely mud. Then back on to the boat and onwards. You see many animals and many of the inhabitants as you travel along the river.
We were lucky enough to see some Macaws at the small clay lick near the Posada Amazonas Lodge.
Other highlights included seeing Capybaranas. These are small wombat like animals that forage on the river bank.
Then you finally arrive at the Lodge.
