The Mérens Horse: The Black Prince of the Ariège Pyrenees

It’s seven in the morning above Orgeix. Mist still hangs between the larch trees when a dark shape appears on the slope, motionless, then a second one, a third. A herd of small black horses, their manes tangled from the night, grazing quietly as if there were no one for miles around. They have no fence. They’ve never really needed one.

These are Mérens horses — and they’ve been at home here for a great deal longer than we have.

On the walls of the Niaux cave, a few dozen kilometres from here, prehistoric hunters painted horses around 14,000 years ago. Their stocky build, thick neck and sturdy stance look, almost exactly, like a Mérens horse today. That’s probably no coincidence: the breed comes from the upper Ariège valley, and it still carries the mark of those very old origins.

The village that gave it its name, Mérens-les-Vals, sits at the foot of the Col du Puymorens, about twenty minutes' drive from Ax-les-Thermes. It was there, on those high mountain pastures where winter lasts a long time and summer is harsh, that the Mérens horse learned to become what it is: hardy, able to cope with very different climates, sure-footed on rough terrain, and calm enough to be trusted with a child or a first-time rider.

The story could easily have ended there, simply, with the mechanisation of farming in the 1950s and 60s. Like many working and draught breeds, the Mérens horse suddenly had little practical use. Numbers collapsed. The breed came close to disappearing altogether.

It was a handful of dedicated breeders who refused to let it vanish, starting in the 1970s. Bit by bit, patiently, they rebuilt the herds and found new ways to value this small black horse: outdoor riding, mountain trekking, show jumping, harness driving — and always, in the background, work on the high summer pastures, true to its original calling.

The gamble paid off. In 2023, the breed celebrated the 90th anniversary of its national breed days, which bring together breeders and enthusiasts every year at Bouan, on the N20 road, close to Sinsat. Since 2017, two new studbooks have even opened in Germany and the Czech Republic, alongside ones already established in Italy, Belgium, the Netherlands and Switzerland. The little Ariège horse, once close to being forgotten, now competes all the way to the Paris agricultural show and Equita Lyon.

The National Mérens Horse Association (Société Hippique d’Élevage de la race Pyrénéenne Ariégeoise), which looks after the breed, is based in Foix, under an hour from Ax-les-Thermes.

All of this history is still very much alive just minutes from your studio. In Orgeix — the same village you’ll already have seen on our hiking route to Lac de Campauleil — Haras des Cimes runs horse treks using mostly Mérens horses, well suited to mountain terrain: sturdy, calm and dependable.

Several options are available, from a first contact with horses to a sportier outing:

The centre welcomes both beginner and experienced riders, with lessons suited to every age — a good fit whether it’s a teenager curious to try riding for the first time, or an adult with a few hours in the saddle already behind them.

For riders dreaming of a multi-day trek, the national "SHERPA Mérens" network connects trekkers with breeders offering overnight stages on horseback across the Ariège Pyrenees — another, longer way to follow the little black horse’s tracks.

Hikers who come across a herd of Mérens horses roaming free on the ridges in summer sometimes picture wild horses. That’s not quite right. The Mérens has always been a companion to Ariège villages — a working, mountain horse and, today, a leisure one too, which has simply kept, in its bearing and its toughness, something of the freedom of the high pastures.

Perhaps that’s what makes a ride near Ax-les-Thermes so particular. You’re not just sitting on a horse. For an hour, or a day, you’re sharing the story of a breed that nearly disappeared — and now gallops again, free, on the slopes where it was born.
