Grottes de Betharram

Cave in Lourdes

The Grottes de Bétharram are a spectacular series of caves located on the border between the Pyrénées-Atlantiques and Hautes-Pyrénées departments in France. These caves offer a unique underground journey, allowing visitors to explore different levels of limestone formations shaped by ancient rivers. The experience is divided into three distinct sections: walking through vast chambers, gliding across an underground river by boat, and finally, taking a small train back to the surface. This multi-layered exploration makes the Grottes de Bétharram one of the most fascinating cave systems in Europe.

Discovered in 1819, the caves were among the first in France to be opened to the public. In 1903, Léon Ross, an artist and early photographer of the Pyrenees, developed the site for tourism, introducing electric lighting and guided tours. The caves feature stunning geological formations, including stalactites, stalagmites, and spongy ceilings that showcase the effects of erosion over thousands of years. The upper levels contain vast chambers, while the lower sections reveal narrow passages carved by underground rivers, offering visitors a glimpse into the natural forces that shaped this subterranean wonder.

One of the highlights of the Grottes de Bétharram is the underground boat ride, where visitors glide across a serene subterranean lake, surrounded by breathtaking rock formations. The journey continues with a 700-meter train ride, which takes guests through tunnels back to the surface. This combination of walking, boating, and train travel makes the visit both educational and adventurous. The caves maintain a constant temperature of 14°C, providing a cool escape even during the summer months.

Beyond their geological significance, the Grottes de Bétharram hold cultural and historical importance. They have been a source of inspiration for explorers and scientists studying cave formations. The site is well-equipped for visitors, offering guided tours that last approximately 1 hour and 20 minutes. Whether you’re fascinated by natural history or simply looking for an unforgettable underground adventure, the Grottes de Bétharram provide a mesmerizing experience in the heart of the Pyrenees.
