Les Barres National Arboretum

Allow 45–75 minutes for a deliberately small introduction. Ask reception to point out suitable open paths in Gouet, then choose just three trees to study. At each, start with the whole silhouette before reading the label. Photograph the label and one distinguishing detail together in your notes. Finish by comparing the three: does each tree spread broadly, rise narrowly or carry its branches in a different pattern? This is a suggested way to use the named collection, not a mapped or measured route.

Gouet is the specific section the operator describes as accessible to people with reduced mobility. Ask about surfaces, gradients, rest points and the route from parking to reception for your wheelchair, mobility aid or pushchair.

Allow another 45–60 minutes if reception confirms the connection is open and suitable. The published approach to Bizarretum passes through the château park, where the famous Thuya aux 80 troncs provides a distinctive stop. In Bizarretum, compare the overall shapes of a few cultivated trees. Try sketching a crown with five lines rather than drawing every leaf. Return using the current visitor plan; this suggestion does not include entry to château interiors.

If you need a continuous step-free route, confirm this extension with reception before leaving Gouet. The Gouet access description does not cover the whole outing.

Give each person one small page with room for three sketches. Choose a whole-tree outline, a leaf or foliage detail visible from the path, and one word that describes the bark. Add names from the labels afterwards. Compare pages over your picnic: a child may remember the branching pattern more clearly than a Latin name. This is a suggested family activity requiring only paper and a pencil.

For an imposing trunk, stand back until its base and surrounding space fit comfortably in the frame. Then make a separate detail photograph rather than stepping over planting edges for a dramatic angle. If a companion is included for scale, keep them on the path and avoid photographing other visitors closely without their agreement.

Try explaining a tree’s outline before reading its label: upright, trailing, compact or spreading. Then see whether the named form helps explain the appearance. Cultivars are selected forms grown for particular characteristics; Bizarretum makes this idea tangible. The Lemosse collection began in 1941, so these unusual shapes also form a different chapter of the arboretum’s history.

A light shower may favour a shorter collection visit in suitable footwear. For prolonged heavy rain, strong wind or thunder, reschedule rather than treating the trees as shelter. The collection visit is outdoors, so check with the visitor team before making a special journey in unsettled weather.

The operator names coast redwood in Continentalis. Once staff or a label has confirmed the tree, look for its flat needles and compare its foliage with the scale-like leaves of a thuja. Kew explains that sempervirens means evergreen. This gives children a useful question to carry through the collection: which trees retain foliage, and which have a seasonal change? These are cultivated specimens, not a native French redwood forest.

The tourist office identifies the château park’s Thuya aux 80 troncs as this species. Make its branching form the main subject of your stop, observing from the permitted path. A western red cedar has tiny scale-like leaves, unlike the redwood’s longer needles. Let the unusual whole tree and the small foliage detail tell two different parts of the story; do not climb, enter a roped area or pull branches closer.

The arboretum has a maple collection, and the young Pardé section of Continentalis is associated with it. If this area is open and suits your walk, compare labelled examples. Record the complete name from each label rather than assigning every maple to a familiar species. Acer is the botanical genus name shared by the different maples.

The operator also documents an oak collection. Oaks form the theme of the October–November 2026 guided programme outside the Journées de l’Arbre event. A guide can help you compare examples without assuming that every oak has the same leaf outline. Quercus is the botanical genus name for oaks. Look for the rest of the name on a tree’s label to distinguish its species.

Les Barres combines living plants, a forestry-school heritage and public education. An arboretum is especially good for noticing variation: the familiar word “tree” includes many ways of making a crown, holding leaves and growing a trunk. The labels let you turn that observation into a comparison you can continue in another garden.

On an advertised spring opening, focus on new growth and differences between foliage. Summer gives time to study the relationship between a trunk, its crown and the shade beneath it. Bring sun protection and water; do not plan your return solely around an old opening-hours leaflet.

Autumn is a good occasion to compare trees in changing colour with those retaining green foliage. Once the public season ends, do not arrive expecting the grounds to be freely open. Organised group visits can be arranged year-round by appointment through EcoloKaterre, subject to confirmation of the programme and access.

A picnic area and shop are listed by Tourisme Loiret. Event pages sometimes advertise food providers, but arrange your meal around the services confirmed for your actual date. Bring water and a snack even if you hope to buy refreshments. Check toilet availability and any baby-changing or access requirements when planning with a young child.

Dogs must remain on leads. Keep both people and dogs out of planted beds, and leave the collection intact for other visitors. Sensory discovery does not mean tasting berries, chewing leaves or rubbing unfamiliar plants on the skin.

Use the visitor destination Domaine des Barres, 45290 Nogent-sur-Vernisson. Parking is listed by the departmental tourist office. Follow the arboretum’s current visitor signs on arrival rather than assuming every entrance to the larger estate is a public gate. Ask about the closest suitable drop-off point if walking from the car is difficult.

Nogent-sur-Vernisson has a railway station; check SNCF for outward and return trains on your chosen date. Arrange the onward journey to the arboretum before buying tickets. Ask the visitor team about a suitable transfer and arrange both directions in advance; do not rely on finding a shuttle or waiting taxi at the station.

For a shorter or lower-effort visit, make Gouet the whole outing and request a few worthwhile stops rather than adding every collection. Ask reception for current information on accessible toilets, seating, path width and wet-weather surfaces. The published accessibility description does not provide enough detail to guarantee the entire visit for every mobility aid.

For late 2026, the Gâtinais Sud calendar lists 24–25 October and 31 October–1 November, with opening from 10:00 to 18:00. The final weekend is an autumn event. Confirm your chosen day at 07 84 32 98 81; these dates are not a recurring annual rule. The calendar does not list 18 October 2026 as a public opening.

Published ordinary admission is €5 full price or €3 reduced. Admission with a guided visit, and event-day admission, is €7 or €5 reduced. Reduced entry covers ages 6–18, students, jobseekers and visitors with disabilities; children aged 5 and under enter free. Guided visits usually start at 15:00, with limited places. The 2026 brochure gives approximately 2 hours and recommends booking. Check the day’s format before committing a younger child to the full tour.

On a tour day, arrive early enough to buy the appropriate admission and find the meeting point without rushing. Use the time beforehand for a short independent look rather than attempting both collections. Take one question along, such as why two trees share part of a name or why a cultivated form looks so different from its relatives. Ask in advance whether English guidance is available.
