Discover Sierra de Aralar hiking: limestone peaks, beech forests, grazing sheep, prehistoric dolmens, and breathtaking views over the Basque countryside.
Hiking in the Sierra de Aralar is a captivating escape into one of the Basque Country's most enchanting natural parks. This protected landscape boasts dramatic karstic terrain, with limestone pavements, deep sinkholes, and lush beech forests that change with the seasons. The trails lead you through vast, high-altitude meadows where sheep and cattle graze peacefully, while birds of prey soar overhead. The park's iconic peaks, such as the pyramid-shaped Mount Txindoki—often called the "Basque Matterhorn"—and the summits of Ganboa and Irumugarrieta, offer challenging yet rewarding ascents. From the top, breathtaking panoramic views unfold across rolling hills and verdant valleys, stretching as far as the eye can see. Along the way, you'll encounter ancient megalithic monuments, including over 30 dolmens that whisper stories of Neolithic shepherds who once roamed these lands.
This moderate hike involves 1,000 meters of elevation gain over a full day. You should be comfortable walking uphill for extended periods and have recent hiking experience on similar terrain.
We'll traverse rocky trails, forest paths, ridge walks, valley floors, and singletrack sections. The variety means you'll need sturdy hiking boots with good ankle support and grip.
We meet at Zurriola Hiribidea, 1 in San Sebastián. This is easily accessible by public transport or taxi from the city center.
This is a full-day tour. With the elevation gain and terrain variety, expect to be hiking for most of the day, though exact duration depends on group pace and conditions.
Bring sturdy hiking boots, weather-appropriate layers, rain gear, sun protection, plenty of water, and snacks or lunch. I'll provide specific kit recommendations when you book.
While rated moderate, the 1,000-meter climb and varied terrain require prior hiking experience. If you're newer to mountain hiking, consider starting with an easier tour to build confidence.
