Olarizu Botanical Garden

The municipal circuit begins beside the welcome letters at the Avenida Olarizu entrance and passes the Infogune. It links forest collections, the small mirador, lake and Casa de la Dehesa before returning through the Mediterranean side and the meadows. Follow the current garden waymarks and map; yew hedges help mark the route. The published distance is 3 km and the approximate walking time is one hour. Allow longer for labels, photographs and a rest.

The council describes a firmed track. At the mirador, avoid the steps towards the lake by returning along the approach path to the descending route described in the official directions. That alternative avoids those steps but does not establish wheelchair suitability for the whole walk.

Start with the map at your chosen entrance, select one forest zone, and plan to return by the same familiar paths. A visit limited to a few labelled plants and one landscape feature is perfectly worthwhile. If using the Casa de la Dehesa for help, fit that stop around its separate public opening hours.

Use the official garden circuit as your backbone, with longer pauses for the lake and a pair of contrasting forest collections. Add the dehesa woodland and a picnic rather than automatically adding more distance. With children, let them choose between the maze and another tree collection; the large site makes tired return walks easy to underestimate.

Cerro de Olarizu, also called Kutzemendi, reaches 709 m above sea level. This number is the summit elevation, not the climb from the garden. Its slopes hold local grassland and scrub, so it offers a different experience from the planted collections. Only add it with time and suitable footwear. Ask at the Casa de la Dehesa for a suitable current route before committing to the climb.

Choose a Mediterranean collection and a boreal one. Look at the leaves still attached to the plants: broad and leathery in many Mediterranean evergreens, needle-like in the northern conifers. Then look below the trees. Olarizu’s collections include shrubs and climbers as well as canopy trees, so the lesson is about a community rather than a row of specimens. Use the labels to check your guesses.

At the lake, compare plants rooted in the margins with those living in the water. The collection is arranged to represent aquatic and amphibious plants from different parts of Europe. A few minutes looking from the path is enough to see why a wetland needs more than open water. Leave stems and flowers in place.

The hedge maze opened in October 2025 and is named for the botanist who spent her final years in Vitoria-Gasteiz. The hornbeam hedges are still a developing feature, so allow time for the planting to mature. Make it a playful extra and agree on a meeting point before exploring.

The CEA offers public activities as well as school programmes. Autumn 2026 listings include a bilingual guided walk through the European forest collections, starting at the Infogune and requiring registration. Use the current event listing for language, meeting point and availability; a general garden visit does not reserve a place on an activity.

The Casa de la Dehesa’s plant exhibition can anchor a shorter visit during showers. Check its opening hours before leaving the city, because the outdoor park being open does not mean the building is. For persistent rain, postpone the meadow and hill portion rather than trying to complete it across sodden ground.

The old oaks in the dehesa connect the garden to the damp lowland woods of the Llanada Alavesa. This is the wild woodland element of the visit, even though it is actively managed and restored. Compare its setting with the deliberately arranged oak collections in the arboretum.

Collection 3.5.1 lists beech together with oaks, chestnut, holly, yew and other woodland plants. Look at the whole group as well as the beech label: the collection is about trees growing with companions, not a single isolated specimen.

Find the holm-oak collection and compare its persistent leaves with the deciduous oaks elsewhere. The Cantabrian collection is a useful reminder that evergreen oak woodland is not confined to the hottest-looking Mediterranean landscapes.

In the boreal zone, use the label to identify Norway spruce. Its regular, pyramidal outline is part of the northern-forest story explained by the garden: a form suited to shedding snow. These trees represent another climate within a planted collection.

The Alpine larch collection makes a good autumn comparison with evergreen conifers. Larches lose their needles for winter, so a bare tree here need not be dead. Check the plant label: the broader high-mountain displays represent several regions and species.

The arboretum is organised into five zones, 29 forest formations and 144 collections. Its design represents differences between geographical versions of a woodland, including the mixture and arrangement of plants. That is why two plots with oaks in them may be telling different stories.

The germplasm bank began operating in 2011. It preserves seeds and other living plant material, investigates germination and grows plants under controlled conditions to support conservation. This is working scientific infrastructure; do not assume that ordinary building opening hours include a laboratory visit.

Make time for the dehesa’s seasonal flowers as well as emerging tree leaves. The municipal account highlights spring daffodils here and on the hill. Look from the paths and leave flowers where they grow; the meadow is habitat, not a picking patch.

Choose a cooler part of the day, carry water and give yourself permission to turn back after one zone. The botanical interest lies in the contrast between plants, so a shorter, attentive walk can work better than covering the full site in strong sun.

Look across the temperate collections for changing leaves, then compare them with evergreen trees nearby. The garden’s autumn walks use exactly this contrast. Keep room in your schedule for a return visit: the colours do not peak on one fixed calendar date.

Buds, branches and conifer shapes become the focus when many broad-leaved trees are bare. Choose a shorter route in wet or frosty conditions and time any indoor stop carefully; the Casa’s winter opening is concentrated at weekends and public holidays.

Public opening is currently Saturday, Sunday and public holidays, 11:00–14:00, from October to March. From April to September it is Thursday 17:00–19:00, and Friday to Sunday and public holidays 11:00–14:00 and 17:00–19:00. There is visitor information and an exhibition about plants. Outdoor park access has no set time restriction.

The official garden map marks picnic areas, fountains and toilets. Use it to locate the facilities nearest your chosen entrance, and check availability on arrival. Carry drinking water anyway. Before relying on a toilet, ask whether it is open and suitable for your needs. Bring refreshments for the outing.

The garden lists approaches from Adurza/Campo de los Palacios, Avenida de Olarizu, Ansoleta/Puente Alto and Gardelegui. Choose the entrance that matches your visit rather than aiming for a generic park pin. Give pedestrians space when arriving by bike.

The garden identifies Line 10 towards Larrein at Heraclio Fournier 42, and towards Aldaia at Esmaltaciones or Zumaquera; it also lists BEI stops at Esmaltaciones and Zumaquera. Check TUVISA’s live service information for the outward and return journey. These stops still require an onward walk to your chosen entrance.

Listed parking options include Avenida de Olarizu, Casa de la Dehesa, Iturritxu and the Ansoleta/Puente Alto area. Pick the one closest to your planned start and follow local parking signs; availability is not guaranteed.

For wheels or limited stamina, start with a short section of the firmed garden circuit and ask which parts best suit your needs. The route description mentions both a slope and steps at the mirador, so a general description of the park as easy walking is insufficient. Confirm gradients, resting places and toilet access with the garden before a visit that depends on them.

The dehesa includes naturally wet and sometimes waterlogged soils. Keep to established paths after rain; crossing the grass is not a reliable shortcut for a pushchair or wheelchair. Treat the hill as a distinct outdoor walk rather than an accessible extension of the arboretum.
