Pantanal - Refúgio da Ilha Lodge
Pantanal de Miranda MS
Pantanal is the largest wetlands area on the planet and most of this wonderful nature is in Brazil, within Mato Grosso do Sul state borders. :-)
Close to Bonito (Around 120 km) and Campo Grande (Around 150 km), the area has tons of options for ecotourism, fishing, farm tours and more!
There are farms that cater to larger groups, there are those that only work with smaller numbers, there are places who specialized on Brazilian people, while some focus on international travelers from all of the world, etc. There are different types of options, each with their own location, logistics, meal services, and access infrastructure (Which can sometimes be limiting as to the kind of vehicle that can handle it). Regardless of which one you chose, you will certainly be in awe with the pantaneira nature (Green, wildlife, Sun, etc) and culture.
Check each option carefully, to be make sure that you choose the best one for the kind of traveler you are and what you want out of your trip!
