The caves were discovered in 1905 by the speleologist Armand Viré.
The Salle des Merveilles houses an underground lake containing distinct prehistoric mineral deposits.
The electric train ride system was installed specifically to allow access to the deep chambers without strenuous hiking.
The caves contain one of the largest concentrations of stalactites found in the Lot department.
The 'black light' show in the Salle des Merveilles was one of the first of its kind used in French cave tourism.
The Grottes de Lacave are a subterranean cave system in the Dordogne Valley accessed via an electric tourist train that transports visitors into the heart of the limestone cliffs. The tour route covers 1.6 kilometers of galleries featuring natural stalactite and stalagmite formations. The final chamber, the Salle des Merveilles, is illuminated by a unique phosphorescent lighting display known as the 'black light' effect. The site is carved directly into the cliff face overlooking the Dordogne River. The internal temperature remains constant at approximately 13 degrees Celsius throughout the year.

Arrive early in the day during peak summer months to avoid large tour groups.
Attempting to visit during heavy rain periods if the water table is high, and failing to account for the constant cool temperature.
Closed annually during the winter season; open daily from spring through autumn.
