4 Best Sights in The Pyrenees, Spain

Take a breathtaking riverside hike (1½ hours) on the Ruta de las Pasarelas loop, which hugs near-sheer cliffs that plunge into rushing turquoise waters. There's a waterfall, a cave, and plenty of placards with information on the surrounding nature and historical buildings. Be sure to bring plenty of water and to arrive early, since parking (follow the signs) is limited. Certain stretches are on metal pathways with steep drops, so those with limited mobility or a fear of heights should skip this one. The trail starts at Plaza de Rafael Ayerbe beside the ayuntamiento (town hall). No bikes or pets are allowed.

A 20-minute drive south of Alquézar drops you at this family-run wine estate that's been in business for over a century. Plan to spend about two hours here between the winery tour and tasting, in which you'll sample bold New World–style wines—Gewürztraminer, Cabernet Sauvignon, etc.—that are a hallmark of the Somontano D.O. Be sure to call ahead or book online.

The Colegiata, originally a 9th-century Moorish alcázar (citadel) for which the town is named, was conquered by the Christians in 1067. An interesting mix of Gothic, Mudejar, and Renaissance details are found in the shaded cloister, and there are biblical murals that date to the Romanesque era. The church, built in the 16th century, contains an almost life-size Romanesque figure of Christ, but restoration has taken away some of the building's charm—its interior brickwork is now only a painted representation. Visits are conducted via guided tour (Spanish only) and usually depart every 30 minutes. 

A UNESCO World Heritage Site, this park within the Sierra de Guara contains more than 60 limestone caves with prehistoric paintings. Some date to around 22,000 BC, though most are from between 12,000 and 4,000 BC. Information, guided tours, and kid-friendly activities are available through the interpretation center in Colungo; check the monthly schedule on the home page. Hours vary, so call ahead.
