Trabuc Cave

The Trabuc cave: visit the largest cave in the Cévennes

An underground gem near Anduze

In Mialet, near Anduze, Trabuc Cave is the largest developed cave in the Cévennes. Used since prehistoric times, it later sheltered Camisards and the brigands said to have given it its name. Today, a remarkable underground route reveals vast chambers, calcite curtains and clear lakes, shaped by water over thousands of years.

Entering Trabuc feels like stepping into another world: outside are Mediterranean light and scrubland; inside, constant coolness, carefully lit darkness and the quiet sound of underground lakes. It is a memorable outing in any weather.

The Hundred Thousand Soldiers: a unique wonder

The highlight is the mysterious Hundred Thousand Soldiers: thousands of small mineral formations standing like a miniature army, whose origins still intrigue specialists. You can also discover the dark reflections of Midnight Lake, petrified waterfalls and large chambers filled with formations illuminated by lighting effects.

A visit full of stories

Visits are guided in summer, with audio guides available before and after the main season. Both explore the cave's history and geology, from prehistoric occupation and Camisard refuge to caving expeditions. Children particularly enjoy the mysterious atmosphere and evocative names of the chambers.

Practical information

The cave is generally open from 7 February to 31 December; check current opening hours and prices on the official website before visiting. Guided visits run during July and August, with audio guides in the shoulder seasons. The temperature stays around 14°C throughout the year, so bring a warm layer even in summer. There are steps, the route is unsuitable for pushchairs, and sturdy shoes are recommended. Allow around an hour.

The underground coolness makes this a welcome outing on hot days, while the sheltered route also suits rainy weather. Trabuc is an appealing option whatever the Cévennes weather.

Getting there from Mas Saint Laurent

Trabuc Cave is around 30 minutes from Mas Saint Laurent in Les Salles-du-Gardon, towards Mialet. The winding road passes through lovely Cévennes landscapes between hills and the Gardon valley. Arrive early for parking, particularly in summer, and check departure times before setting off.

Combine your visit with other discoveries

Nearby, the Musée du Désert in Mialet tells the story of the Camisards and Protestantism in the Cévennes, while the Pont des Camisards crosses the Gardon. You can also continue towards Anduze and La Bambouseraie, a few minutes away, combining nature, history and heritage without long drives.

If you are also considering La Cocalière Cave, a little further north, both are worth visiting but have different attractions: Trabuc has its Hundred Thousand Soldiers and distinctive atmosphere, while La Cocalière offers a small train. Guests staying several days often visit both.

Why stay at Mas Saint Laurent

The Mas is an ideal base for this part of the Cévennes. After the coolness of the cave, return to the swimming pool and terrace, then enjoy local cooking at La Table Cévenole. Discover the area without lengthy journeys and spend your evenings in peaceful surroundings, in a historic building just minutes from Alès.

A cave rich in history

Trabuc is both a geological wonder and a place closely linked to Cévennes history. Occupied since prehistoric times, it has sheltered people over the centuries, including Protestant Camisards. Brigands are later said to have used it as a hideout; the name Trabuc may refer to the blunderbuss, an old firearm. From the nineteenth century, cavers gradually explored its size and treasures, including the famous Hundred Thousand Soldiers. These stories add another dimension to the visit: beyond the mineral scenery lies a place shaped by human lives, fears and adventures.

Trabuc with children

Children enjoy the mysterious atmosphere, the contrast between cool cave air and the heat outside, the chamber names and the Hundred Thousand Soldiers. Guides or audio guides combine stories and lighting to hold their attention. Bear in mind that the route has steps and sometimes damp sections, so it is unsuitable for pushchairs or very young children who are not yet walking. Bring warm clothing: 14°C soon feels cool. With these preparations, Trabuc can become a family favourite.

What to explore around the cave

Trabuc is well placed for a full day of discoveries. Visit the Musée du Désert in a traditional Mialet hamlet to learn about the Camisards and Cévennes Protestantism, or pause by the river at the Pont des Camisards. Anduze, La Bambouseraie and many river swimming spots are nearby. Combine culture in the morning, the cave around midday and the river in the afternoon, without travelling far from the Mas. This is one of the advantages of staying within the Anduze–Mialet–Alès area.

Practical tips

Bring a warm layer and sturdy closed shoes. Check visit times, particularly in high season, and arrive early for parking. On very hot days, visit around midday to enjoy the underground coolness. Combine the cave with the nearby Musée du Désert for a full day out.
