A little-visited natural park near Vitoria-Gasteiz with ancient beech forests, dramatic limestone karst, and excellent hiking trails that are almost entirely free of tourists.
The natural park area around Zaldiaran and the Sierra de Badaia ridge near Vitoria-Gasteiz in Álava encompasses some of the most extensive and least-visited ancient beech and oak woodland in the Basque Country. The landscape here is characterised by rolling forested ridges, limestone karst formations, deep ravines, and scattered farmsteads and hermitages that reflect centuries of pastoral land use in this corner of the Basque hinterland.
The forests are predominantly ancient Atlantic beech woodland — gnarled trees draped in ferns and mosses that create a primordial, cathedral-like atmosphere on cloudy or misty days. The limestone geology produces dramatic features including caves, sinkholes, and springs, and the park's trails cross a landscape that feels genuinely remote despite being only 20–30 km from Vitoria-Gasteiz city centre. The contrast between the easily reachable capital and this wild forested terrain is striking.
The trail network is waymarked and maintained by the Álava provincial government, with routes of varying difficulty ranging from gentle valley-floor walks to ridge traverses with views extending in clear conditions across to the Sierra de Gorbeia to the north and the Castilian meseta to the south. The ridge of the Sierra de Badaia provides some of the finest and most accessible mountain panoramas near Vitoria-Gasteiz.
The park is excellent for wildlife observation: red squirrels, roe deer, badgers, and various raptor species including red kites are regularly sighted. Wildflower diversity is high in spring, with woodland orchids, wood anemones, and marsh marigolds along the wetter valley paths. The beech forest reaches its most dramatic visual peak in October and November when the canopy turns gold and copper.

Tips for visiting
- The trail from Otaza village to the Sierra de Badaia ridge and the Zaldiaran area is the most rewarding route and has panoramic views in clear weather
- Download trail maps or offline GPS routes before visiting — mobile signal is unreliable in the forest interior
- Wear waterproof footwear as paths can be wet and muddy year-round in this Atlantic climate
- The park is most visited on sunny Sunday mornings in spring and autumn — midweek visits are significantly quieter
- Combine with Vitoria-Gasteiz (20–30 km north) for a day that mixes forest walking with the city's medieval quarter and contemporary art museum
When to visit
October and November for spectacular autumn beech colour — the park's most visually dramatic season. Spring (April to June) for woodland wildflowers, bird activity, and fresh green growth. Avoid January and February when higher ridge trails can be snow-covered and icy.
Accessibility
The natural park trails are not suitable for wheelchair users, involving uneven forest paths, roots, and muddy terrain. Some flatter valley-floor sections near car parks may be manageable for visitors with moderate mobility. No adapted facilities exist within the park interior.
