The caves are located in a cliff face comprised of soft limestone, which was easily excavated by local residents over several centuries.
The name Régulus refers to a 74-gun ship of the French Navy that was set on fire and sunk by its own crew in 1814.
Historically, these dwellings were favored by smugglers who utilized the labyrinthine passages to store goods away from the authorities.
The site illustrates the adaptation of human habitat to the vertical landscape of the Gironde cliffside.
These caves served as a refuge for the local population during various historical conflicts, including the Wars of Religion.
The Gironde Estuary visible from the caves is the largest in Western Europe, acting as a major waterway for international shipping.
The site preserves traditional 'carrelet' fishing techniques in its visual landscape, involving square nets lowered into the water.
Parts of the cave system remain as they were naturally hollowed by water action before being modified by human occupation.
Grottes du Régulus are troglodytic dwellings carved directly into the limestone cliffs overlooking the Gironde Estuary. Originally formed by natural erosion, these caves were later expanded by humans for use as dwellings, smuggling hides, and defensive positions. The site takes its name from the French warship Le Régulus, which was scuttled in the estuary in 1814 to prevent it from falling into British hands. Visitors walk through a series of interconnected galleries that showcase how inhabitants lived from the prehistoric era through the 20th century. The site provides an unobstructed view of the largest estuary in Western Europe and its unique 'carrelet' fishing platforms. Displays include period furniture, tools, and historical exhibits illustrating the geological and social history of the region. The complex features both natural voids and human-engineered architectural additions.

Wear comfortable, non-slip footwear as the limestone floors can be uneven and occasionally damp.
Plan your visit to coincide with low tide if you wish to walk along the base of the cliffs to view the cave openings from below.
Bring a light jacket, as the interior temperature remains cool throughout the year regardless of the external weather.
Avoid visiting during heavy rain as the paths can become slippery and the visibility of the estuary is significantly reduced.
Closed in January; typically open from February through November with varying seasonal daily availability.
Maintain quiet voices, do not touch historical artifacts, and keep to marked pathways to preserve the soft limestone structure.
