Santa Catalina Botanical Garden

Santa Catalina works best when you give equal attention to the plants and the stonework.

About

Santa Catalina works best when you give equal attention to the plants and the stonework. The garden occupies the grounds of a former fortified residence and convent, so a change of planting can bring you alongside a surviving wall or into a different part of the historic complex. Look at the masonry as well as the flowers: the sequence of rooms and walls is part of what gives the planting its setting.

Three environments help you read the place. The Umbría supports trees associated with cooler Atlantic conditions; the valley bottom brings moisture-loving planting and ponds; the Solana holds plants suited to drier, sunnier conditions. Compare their leaves and growth shapes as you go. You do not need to identify everything to notice how differently plants solve the same problems of light and water.

The collection mixes local vegetation with cultivated plants from farther afield. A planted cedar or ginkgo tells a different story from a free-flying butterfly. Both belong in your visit, but a labelled specimen is easier to find than an animal: leave room for an unexpected sighting without making one the condition of a successful afternoon. Don't forget to bring the Snappit nature identification app along to scan local species.

The original tower-house dates from the late 13th or early 14th century. The Martínez de Iruña family gave the property to the Jerónimos in 1407; the Agustinos followed in 1472 and developed the convent. After the monks left in 1835, the complex was burned during the First Carlist War in 1836. Iruña de Oca Town Council acquired it in 1999. Those changes help explain why domestic, defensive and religious remains share one garden.

What to do here

Explore the garden’s open paths, spend time with the convent remains and bonsai display, then make a longer stop beside the butterfly planting if insects are active. Use the entrance information to choose the order that suits your group.

Seasonal info

The published calendar closes the garden from 30 November until March or April. Check the actual reopening announcement and booking calendar before planning a spring visit.

Accessibility

Slopes, narrow stepped sections, uneven ground and steep metal stairs affect access to different areas. Arrange any required assistance before buying tickets; see the access section below.

Walks and routes

A first visit: allow 1½–2 hours inside

Start by checking which areas are open and choosing a manageable sequence from the entrance information. Make the ruins and bonsai display your main stop, then compare the valley-bottom planting with a section of the sunny or shaded hillside. Finish with whichever detail caught your attention first. This is a suggested order of interests, not a waymarked circuit; follow the garden’s signs and staff directions.

A family visit with one small mission

Ask everyone to choose a tree they would like to draw. Let the bonsai display provide ideas, and use the wish tree as a separate pause if it is available. Keep the plan flexible enough to stop for an insect or a rest. A few remembered discoveries are more useful than hurrying children through every planted area.

Things to try

A miniature tree with a full-size story

At the bonsai display, choose one tree and look at the relationship between trunk, branches and pot. Then compare its outline with a full-size tree elsewhere in the garden. Bonsai is a method of growing and shaping living trees, not the name of a miniature species. The display belongs to members of Asociación Bonsai Araba.

Give the butterfly planting a little time

The Oasis de Mariposas supports wild butterflies with plants that feed caterpillars and adults. Pick a spot on the path and wait rather than following each insect through the beds. A photograph of the upper and lower wings, when the butterfly settles naturally, is much more useful than a blurred chase.

Join a guide for the building as well as the botany

The general tour combines plants, ponds and the story of the convent. The published guided product is for groups of 10–30, in Spanish or Basque, and requires a phone call to confirm availability before reservation. If you are travelling alone or need another language, ask what can actually be arranged: do not assume a daily English departure.

If the paths are wet

Shorten the plan if slopes or stairs feel insecure, and ask staff which open areas are sensible that day. The ruins do not turn this into an indoor attraction. If rain would make the visit uncomfortable, use the operator’s virtual visit to explore the setting and choose another date; check ticket conditions before assuming a change or refund is possible.

Wildlife and habitats

Japanese maple (Acer palmatum)

Look for the hand-like arrangement of the leaf lobes on this cultivated maple. Its outline is a useful contrast with the ginkgo’s fan-shaped leaf. Leaf colour varies with the specimen and season; a red leaf alone is not a dependable identification.

Himalayan cedar (Cedrus deodara)

This cultivated conifer keeps its needles through the year. Needle clusters and drooping shoots help distinguish its shape from the broad-leaved trees around it. Look at the tree as a whole before trying a close-up: the architecture is part of the clue.

European beech (Fagus sylvatica)

Look for beech in the bonsai display: it gives you a chance to recognise a familiar woodland tree at an unfamiliar scale. Look for oval leaves and their softly wavy edges when in leaf. A small pot changes how a tree is grown, not its botanical identity.

Ginkgo

Its fan-shaped leaves make an approachable first identification, especially when they turn yellow in autumn. Compare a leaf’s outline with the nearby diversity of needles and lobed foliage. Autumn colour makes this planted tree particularly memorable, though the exact timing changes from year to year.

Lavenders (Lavandula)

The aromatic planting includes lavenders. Use the plant label to establish which kind you are looking at, and enjoy flowers and scent without picking or rubbing the collection. Different lavenders can look quite distinct, so compare more than flower colour when you read the label.

European robin (Erithacus rubecula)

Watch for a small bird with orange across its face, throat and chest, sometimes pausing low in vegetation or searching the ground. Robins are among the garden’s wild birds. Give one space to continue its own business; feeding it is unnecessary.

Orange-tip (Anthocharis cardamines)

A male’s orange forewing tips are the obvious clue, but females lack them. Both sexes have mottled green-looking underwings. With this wild visitor, a white butterfly passing quickly may leave you without enough detail for a firm identification.

Painted lady (Vanessa cardui)

Look for orange-and-black upper wings with pale spots near the dark forewing tips. This wild visitor can bring a flash of colour to the planted beds. Wait for a natural pause on a flower and use your camera’s zoom; do not catch it or move stems to improve the view.

Stories and discoveries

A tree gets a second life

The Árbol de los deseos uses a former carob tree that once stood at the entrance. After it died, it became a storytelling feature inside the garden. It makes a good change of pace for children between the plant beds and the heavier history of the ruins.

The hollow helps shape the collection

The garden’s form creates different exposures within one small site. That is why the three named zones matter: their mix of shade, sun and valley-bottom conditions helps explain the planting more clearly than a simple country-by-country collection would.

When to visit

Spring and early summer

Look for new leaves and differences between trees grown in the beds and as bonsai. For butterfly watching, choose a mild, bright spell if you can and accept that the best moment may be brief. Reopening after winter must be confirmed before travel.

Summer

Use the longer weekend opening window to avoid rushing. Alternate sunny planting with shaded areas and take water breaks before anyone becomes tired. If a cultural or astronomy event interests you, reserve that particular activity and check its admission arrangements separately.

Autumn and winter

Ginkgo and Japanese maple offer good reasons to look closely at leaves as they change colour. Choose an earlier arrival in the short autumn opening window, especially if you need a long approach. Winter is a closed-season planning opportunity, not a promise of a quiet open garden.

Getting there and practical advice

Admission and current opening pattern

Book in advance. Checked on 17 October 2026, the standard self-guided ticket is €3.60; children up to 10 are free except in guided groups. The October–April timetable lists Thursday–Sunday and public holidays, 11:00–15:00, subject to the winter closure. May–September lists Thursday–Friday 11:00–15:00 and weekends/public holidays 10:00–20:00. Recheck the selected date and any special-event conditions.

Plan your essentials

The ticket office has cycle racks. Bring what you need for the outdoor visit rather than relying on refreshments being available. If accessible toilets, baby-changing space or a specific rest facility are essential, ask the garden about their location and current availability when you arrange the visit.

Driving to the garden

Use the operator’s directions for Santa Catalina at Trespuentes, in Iruña de Oca/Iruña Oka. There are three parking areas at different positions on the approach. Leave extra time for the uphill walk to the ticket office and ask which parking area is open and most appropriate for you; proximity does not remove the gradient.

Coming by bus

Some Alavabus line 13 services call at Trespuentes, while others do not. Check the complete timetable for your day and both directions, then allow separately for reaching the hillside garden. A village bus stop is not the garden entrance; if the climb is unsuitable, arrange an appropriate onward journey before buying admission.

Arriving by bicycle

You can leave a bicycle at the ticket-office racks, but bicycles and skates are not allowed inside the garden. Treat the approach as part of your journey and save enough energy and daylight for the return.

Match the visit to the terrain

The operator describes hills, narrow steps, natural surface irregularities and sharply inclined metal stairways on the way to different botanical and ruined-building areas. Ask about a specific area and access method, rather than a general yes/no accessibility label. For a pushchair, discuss where it can go and where carrying it would be impractical.

Book assistance before buying the ticket

The advertised support includes a Joëlette all-terrain chair and directional bars for blind or low-vision visitors; sign-language interpreting is listed for eligible events and organised groups, not ordinary self-guided visits. The operator requests at least 48 hours for self-guided visits and five days for other assistance requests, subject to availability. Confirm the arrangements first. The support page asks for disability documentation and states that tickets are non-refundable. Start through the official access page or the garden on +34 688 897 048.

Frequently asked questions

No. The operator requires an advance reservation before you come, including for a self-guided visit. Use the official ticket page and check your chosen date before setting off.
Yes, with suitable supervision and a realistic plan for the hills. Under-12s must be accompanied at a ratio of at least one adult to three children; all under-16s must remain supervised. The published rules prohibit climbing trees, ruins and railings.
Dogs are permitted under control on a sturdy lead or chain no longer than 1.5 metres. Keep them away from wildlife and other visitors, and follow any additional muzzle requirements that apply to your dog.
Only with the appropriate arranged activity. The garden promotes astronomy events, but its ordinary daytime ticket and hours do not give permission to remain after closing. Check the current programme rather than arriving at dusk on spec.
Do not assume so. Ask the garden which areas work for your needs and how to reach them. A shorter visit or an arranged assisted visit may be more appropriate than trying to cover every level.
