The national park covers the limestone escarpment that rises immediately south of Tlemcen — about 8,200 hectares of cedar, holm oak, and Aleppo pine, with limestone cliffs, caves, and several seasonal waterfalls. The Cascades of Lourat (El Ourit) on the eastern edge are the best-known feature: a series of falls reached by a cable car from the city, with viewing platforms cantilevered out over the rock.
Other access points include the Plateau of Lalla Setti, where there is a famous shrine and panoramic views back across the medina, and the trailheads to several limestone caves used since prehistoric times. The park is busy on weekends with Algerian families picnicking; weekdays are quieter and the wildflowers on the upper slopes in spring are striking. Bring water and sensible footwear.
