Olarizu is a prominent park in Vitoria-Gasteiz, dominated by the distinctive Olarizu Hill and its summit cross. The site encompasses a botanical garden known as the Olarizu Botanical Garden, which specializes in European vegetation. A large, man-made pond is located near the park entrance, acting as a focal point for local birdlife. The hill features a zig-zagging path leading to the summit, which stands at approximately 709 meters above sea level. This park serves as the southern anchor of Vitoria-Gasteiz's Green Belt, a network of interconnected nature trails. The summit provides a panoramic view of the Llanada Alavesa plain. The park area includes diverse habitats, including oak forests and reconstructed wetlands. The site is historically significant to the city's annual Olarizu pilgrimage held in September.
