Aven Armand Cave
Located on the Causes-Mejean plateau in the Cevennes National Park, the Caves of Aven Armand are one of France’s most awe-inspiring natural wonders. Discovered in 1897 by Louis Armand and Edouard-Alfred Martel, this underground marvel features a breathtaking stalagmite “forest,” vast chambers, and unique geological formations that captivate visitors. Here’s everything you need to know to plan your visit to Aven Armand Cave.
Wonders of the Aven Armand Cave
Subterranean Forest of Stalagmites
Considered one of the most beautiful caves in the world, the stalagmite “forest” of Aven Armand Cave contains more than 400 pillars, some reaching up to 30 meters. Known as one of the highest stalagmites in the world, these formations create an almost surreal experience reminiscent of a Jules Verne novel.
Cathedral-like Chamber
The main chamber of the cave is 100 meters long, 60 meters wide, and 45 meters high—large enough to hold Notre Dame de Paris. The delicate interplay of light in this vast space enhances the beauty of the stone curtains and crystal formations.
“Sound and Light Show: Journey to the Center of the Earth”
This immersive show casts colors and shadows over the cave formations, enhancing the magical atmosphere. The combination of natural beauty and theatrical effects brings the caves to life.

Practical Information
The Caves of Aven Armand are located in Hures-la-Parade, Lozère, in southern France. Follow these tips to make the most of your experience:
- Access: The cave is accessible by car via a scenic route through the Causse Méjean plateau. Visitors from Béziers and surrounding cities can combine their trip with other nearby natural sites.
- Reservations and Accessibility: The tour is guided, with several stops along constructed trails. Due to the terrain and stairs, wheelchair access is limited. Booking tickets online in advance is highly recommended, especially during peak season.
What to Bring
- Warm clothing: The cave maintains a year-round temperature of around 12°C (54°F) with high humidity. Sweaters and jackets are essential.

Tips for a Memorable Visit
- Arrive early: For a quieter experience, arrive in the morning. Nearby cafes open early, so you can enjoy a coffee before the tour.
- Take the cable car: Begin your journey with a cable car ride down to the caves, offering a panoramic view of the site.
- Respect the environment: Avoid touching the delicate stalagmites and stalactites, which have formed over millions of years.

Tour Highlights
Stone Tree Forest
The “virgin forest” of stalagmites is the most distinctive feature of Aven Armand Cave, with highlights that include:
- Over 400 towering stalagmites with fantastical shapes.
- One of the tallest stalagmites in the world, at 30 meters high.
- Mineral formations that appear almost organic, blending natural artistry with geological wonder.
Sinkholes and Vertical Shafts
Aven Armand features a distinctive “aven” sinkhole—a vertical shaft 75 meters above the cave ceiling—followed by a second, even deeper shaft. These formations reveal the geological forces that shaped the cave over millions of years.
