Saint-Médard-En-Jalles: Wetlands, the Jalle and history

In Saint-Médard-En-Jalles, nature, paths along the Jalle and traces of industrial history come together. You can plan your trip around several different themes: a wetland home to dragonflies and amphibians, nature activities throughout the year, a puzzle trail with an approximate duration, and the historic entrance to the Poudrerie. This lets you tailor your stay to your particular interests, whether biodiversity, waterside paths or the history of the powder mills.

The Jalle, wetlands and Parc des Jalles

The Jalle rises west of Saint-Médard-En-Jalles and flows to the Garonne. Near the Bois des Sources, a wetland is home to dragonflies, amphibians and typical vegetation, including black alder trees. The watercourse and wetland give the municipality’s nature theme several distinct, tangible points of interest.

Saint-Médard-En-Jalles is part of the Parc des Jalles. Walks and events take place there throughout the year, along with measures to promote biodiversity. At the European level, its designation as a Natura 2000 site protects biodiversity and its sensitivity. Nature is therefore not just a feature of individual paths: events and measures to support species diversity also shape what the Parc des Jalles has to offer.

Routes and outdoor activities

Escal en Jall is a Tèrra-Aventura puzzle trail in Saint-Médard-En-Jalles. It takes about 1.5 hours and can be completed on foot or by bicycle, introducing visitors to the city’s plant heritage, biodiversity and history. The approximate duration provides a useful guide for planning your time. As route details may change, it is worth checking the latest route description before setting out.

At the Bords de Jalle de Gajac, a riverside promenade follows the Jalle to the Thil and Gamarde springs. Features of this area include water features, plant islands, a plant maze and an arboretum. Unlike the puzzle trail, the focus here is on the waterside path, the named springs and the landscaped plantings.

The town of Saint-Médard-En-Jalles and its partners offer nature outings, educational workshops and opportunities to encounter local wildlife throughout the year. These add further nature themes to the walks and events in the Parc des Jalles. Paths run alongside the grounds of the Château de Belfort, where walkers and spectators can watch horses and riders in action.

The history of the Poudrerie

The historic entrance to the Poudrerie is still visible at the Espace Dupérier. The site beyond the gate is closed to the public, except for a section used by certain associations. Both the visible entrance and the restricted access are important conditions to bear in mind when visiting this historic site.

The history of the Poudrerie also includes Jehan Dupérier: he acquired a plot on the site, where he had six powder mills built. They were known as “Les moulins à poudre du Roy” (the King’s powder mills). The mills provide a tangible connection to local industrial history, while the site beyond the gate remains closed to the public.

A distinctive place to stay

La Station orbitale is an unusual accommodation open to everyone. It can be used free of charge and by reservation only. These conditions differ considerably from booking a hotel: if this accommodation suits your plans, be sure to factor in the reservation requirement.

Whether your focus is the wetland, a route, wildlife-related activities or industrial history, Saint-Médard-En-Jalles offers several distinct themes to consider when planning your trip. When choosing a hotel, you could first think about which of these aspects matters most for your stay.
