The Gours pools in the cave are considered some of the most beautiful in Europe due to their scale and pristine preservation.
The cave serves as a natural maturation cellar for specific local wines, with bottles placed directly in the underground riverbed environments.
The temperature inside the cave remains a constant 14 degrees Celsius throughout the entire year.
The cave network was originally discovered in 1836 by a local hunter searching for a missing rabbit.
The site hosts an annual event involving the descent of wine bottles into the caves for aging.
Grotte Saint-Marcel is a significant cave system situated in the Ardèche Gorges, featuring a 600-meter accessible tourist route. The site is notable for its 'Gours' pools, which are natural rimstone dams creating a series of cascading underground basins. Beyond its geology, the cave functions as an active cellar for the aging of AOC Côtes du Vivarais wines. Visitors can observe the transformation process of these wines, which benefit from the cave's constant temperature and humidity. The cave features a sound and light show integrated into the rock formations. It is a major speleological site connected to an underground network spanning over 50 kilometers. The location provides a direct view into the dramatic karst topography of the Ardèche region.

Bring a warm sweater or jacket even in summer, as the constant cave temperature is significantly cooler than the surface.
Wear shoes with good grip, as the cave floors can be damp and slippery.
Book the wine-tasting experience in advance if you wish to participate, as these sessions have limited capacity.
Do not wear flip-flops or open-toed sandals, as the terrain is uneven and walking surfaces can be wet.
Open daily during the high season; schedule is limited or subject to seasonal closure during winter months.
Do not touch the stalactites or stalagmites; avoid using camera flashes near wine aging racks.
