Three thousand six hundred hectares of oak north of the vineyards, set on a dome of sandstone. It is the largest oak forest in the south-west, and one of the quietest. Here is how to enter it without going in circles.
The Grésigne isn't visited like a monument: there is no entrance, no ticket office, no single waymarked loop. It is a round, domed massif, ringed by hilltop villages that hold its gates. You go in through one of them, sink under the oaks, and come out through another.
What follows isn't a route to walk in order, but six markers to understand where you're treading — and to choose your gate according to the mood of the day.
This is the easiest way in. The village, one of France's Most Beautiful Villages, clings to a spur above the forest: you park below the ramparts, take a coffee on the square, and the first trails head straight off under the oaks. The view from the Barry promenade gives you the measure of the massif — a green swell all the way to the horizon.
You cross it without noticing: a long dry-stone wall, smothered in moss, running under the trees. It dates from the 17th century, when the royal forest supplied masts for the navy of Louis XIV. In 1666, Colbert sent the forester Louis de Froidour to bring order to an exploitation grown anarchic; the wall served to enclose and protect the wood. Kilometres of it survive, still legible towards Fontblanque and Hauteserre.
Sixty percent sessile oak, the rest pedunculate oak, hornbeam and downy oak — almost no conifers. The trunks are straight, tall, well spaced: this is a forest you see through, not a closed undergrowth. Look up in spring for the tender green, come back in October for the gold. The high point reaches 491 metres.
For a proper walk, this is the safe bet: a marked loop that drops into the heart of the massif along a stream, with a few honest climbs but nothing brutal. Allow two hours at an easy pace. The GR46 long-distance path also skirts the forest for anyone wanting to link the villages on foot.
It is one of Europe's great entomological sites: the third forest in France for beetles, with close to 2,400 species recorded. Add more than a hundred breeding bird species, plus red deer, roe deer, wild boar, pine marten, wildcat and genet. You hear them more than you see them — the forest is a Natura 2000 site for exactly this reason.
The other balcony village, on the vineyard side. Castelnau-de-Montmiral closes the forest to the east and today oversees its administration. Its arcaded square, its lanes, its view over the Vère valley make it a good starting point — or a good finish, glass in hand, after the walk.
The Grésigne doesn't give itself to a camera. It is a forest you listen to — wind in the oaks, and nothing else for hours.
