For a taste of some pleasant interior geography in the Algarve, we recommend a run in the Fonte Benémola, a reservoir which set in 400 hectares of protected land near Loulé. The 4 km loop trail is a rustic landscape of meadows, woodland and rural farmland. Sights include freshwater springs, damns, watermills, old lime kilns and ancient waterwheels. Popular for birdwatching and lovely flora.
