Ecoparc Una 

Visitors to StelaMares have the opportunity to visit one of Brazil's most biologically diverse areas – the Atlantic forest of southern Bahia.

This area provides critical habitat for species that live nowhere else on earth and with only 8 percent of the original forest remaining, is one of the most endangered ecosystems in the world.

At Una Ecopark – a private forest reserve, visitors can take the 2km canopy walkway through the rainforest to see endangered species such as the golden-headed lion tamarin and the yellow-breasted capuchin monkey.
