Fodor's Expert Review Parque da Ferradura

This private nature preserve has three lookouts to the Vale da Ferradura (Horseshoe Valley), formed by Rio Santa Cruz. You can hike across trails in more than 500 acres of pine forests through hilly countryside. A strenuous but rewarding two-hour trek reaches Rio Caí near its source. Make sure you remain alert while hiking: it's quite common to spot a variety of wildlife here, such as deer, anteaters, and badgers.
