This guide describes 40 graded walks, ranging from gentle family strolls to strenuous mountain hikes (including Portugal's highest peak Torre). The mainly circular routes range from 5 to 25km, and there are also two longer walks of 2 to 4 days duration. The walks are spread throughout Portugal, with a focus on the country's many natural and national parks, including Peneda-Geres, Serra da Estrela, and Costa Vicentina. Clear route description is illustrated with 1:50,000 mapping and a route summary table makes it easy to choose the right walk. As well as practical travel advice, there is information on Portugal's geology, history, plants, wildlife, and agriculture and on numerous local points of interest. From the rugged mountains of the north to the UNESCO-listed Rio Douro river valley, from traditional schist villages to the unique geology of the Algarve coast, the walks have been carefully selected to showcase some of the best Portugal has to offer. They take in granite peaks, wildflower meadows, woodland, waterfalls, castles, churches, and archeological remains.
