Fodor's Expert Review Parque Nacional da Peneda–Gerês

The 172,900-acre park, sitting on the border with Spain, was created in 1970 to preserve the region's diverse flora and fauna. It remains Portugal's only national park, and even a short trip shows you wild stretches framed by mountains, woods, and lakes. The park's headquarters is in Braga, but you can get a map of the more than 30 marked trails at any local tourism office.
