Brazil – Travel and see the Pantanals

We are therefore 4 to travel to Brazil next August. I plan to stay in Sao Paolo or Rio, but the decision depends on how you advise me!

The goal is to spend 5 days in the Pantanals and then go trekking in Brazil.

My question is – Where is the best place to stay in the Pantanals? At first glance, we would need a flight from Sao Paolo / Rio to Cuiba?

In addition, are there any tourism activities that you would recommend? Preferably an all-inclusive at fair prices!

Any help is appreciated 🙂
