Hiking and Horseback Riding, Parque Natural de Aralar
Concierge.com's insider take:
With its gorgeous mountainous terrain and dramatic coastline, the Basque country is prime territory for outdoor activities. For a particularly breathtaking location where you can hike and horseback ride, head about 30 minutes south of San Sebastián to the Parque Natural de Aralar, a 27,000-acre nature preserve that has 4,000-foot-high peaks crisscrossed with trails. The park also has more than 30 prehistoric dolmens (Stonehenge-like prehistoric monuments that date back to the Neolithic period) and cave dwellings. Though you can explore the park on your own, it's best for newcomers to pick up maps and arrange guided visits through the helpful folks at the tourism office in Ordizia, open seven days a week (24 Santa María; 34-943-882-290; open MonFri 101 and 47; weekends 112 and 47).
