This former 20ha farm, where polyculture was practiced, brings together a great diversity of landscapes, natural environments and species.

Witness to a bygone past, the landscapes and micro-environments of the valleys of the former moor are found here.

L’airial Larousse: a few steps from a renovated residential farm and a traditional bread oven, a barn-goat barn houses a herd of 70 goats near a laboratory where cheese is made.

The ponds: from numerous sources, their waters are divided into several bodies of water. An observation platform and a hide allow you to observe European pond turtles.

Lawns and meadows: the grazing activity that exists there contributes to their maintenance. Their sandy substrate is home to a wide variety of annual and perennial species.

Two tourist accommodation (including one with the tourism and handicap label)

A dormitory for pilgrims (6 places)

To make the school public aware of the major environmental issues, a space has been reserved for welcoming students within the airial (classroom and laboratory).

In addition to these developments, Mont de Marsan Agglo has entered into a partnership with Cistude Nature, an approved association, for the design of thematic activities adapted to different school audiences.

This approach has made it possible to develop significant visits to the site by this public.

Airial Larousse

The airial Larousse is a typical rehabilitation of a Landes farm of yesteryear, it includes a residential farm, a bread oven, a henhouse, a goat house, so many resurrected memories of the life of yesteryear, to be discovered near ponds of the Nine Fountains.

Natural environments

The ponds of the Nine Fountains, which date from the mid-19th century, are home to interesting environments, particularly the wetlands located near the banks (sedge grove, willow grove, etc.).

The wetland located in the northwestern part has developed well. On the other hand, the southern bank hosts equally humid vegetation, but on a narrower strip. This vegetation finds a continuity with the mixed afforestation of the hillside composed, among other things, of old oaks, old chestnut trees and old pines, which constitutes a favorable environment for avifauna.

The presence of springs with well-developed aquatic vegetation (Sedges, Ache nodiflora, Pondweed, Duckweed) is potentially interesting for dragonflies and amphibians.

These environments serve as a refuge for a variety of fauna, some of which are emblematic, such as the pond terrapin or the otter.


The landscaped car park located at the bottom of the airial has eleven spaces, including two reserved for people with reduced mobility, as well as dry toilets.

A few meters below, the development of the ponds reveals new paths in the process of being finalized. Information panels are present along the paths. Some have the particularity of having 3D wooden sculptures as well as Braille text, intended for visually impaired visitors.

Four wooden structures are located

an observation platform with a view of the main pond

an observation hide allowing you to observe the species present in complete discretion

a 44-meter footbridge to cross the wet meadow

a pontoon allowing walkers to get as close as possible to the pond.

Two picnic areas are also available to visitors. Another car park located at the level of the airial provides direct access to all of the built heritage.
