Iguazu Falls is one of the largest waterfalls on earth; made up of many cascades it is located in the border of Brazil and Argentina. It was declared World Heritage Site by UNESCO in 1984 and its surrounding rainforest boosts over 2,000 species of flora and fauna including tapirs, ocelots, jaguars and caimans.
The pristine natural surroundings are complemented by world class hotels offering five star activities from the most unique spa treatments to the most daring adventures. There are alternatives for all members of the family like touring the rainforest, bird watching or discovering the colors of the gemstones at a nearby mine.

Yriapu Tropical Forest will concentrate most of the investment that will be guided by sustainable practices including low density hotels, low rise constructions and usage of local materials.
