Dedicated to understanding the meteorite crater that shaped the entire Charlevoix landscape, this centre offers guided tours exploring the geology, origin, and human consequences of an impact that occurred 350 million years ago.
The Charlevoix astroblème is the fundamental geological attraction that explains the entire region's distinctive topography: this meteorite crater spanning 56 kilometres in diameter, created by the impact of a two-kilometre meteorite approximately 350 million years ago, has shaped a mountainous landscape that drops steeply into the Saint Lawrence River, directly influencing human settlement patterns and tourism development throughout the Charlevoix territory for centuries. Daily guided tours organized in July and August from Baie-Saint-Paul by a non-profit scientific organization, and available upon request throughout the rest of the year, allow curious visitors to better understand the geology of this exceptional impact, its cosmic origins, and the human developments made possible or constrained by this particular topography, not to mention the diverse flora that this unique geological configuration has fostered over millions of years following the impact. The astroblème remains largely invisible at ground level to the untrained eye, its circular form becoming truly perceptible only from elevated vantage points, particularly from the summit of Mont du Lac-des-Cygnes in Parc national des Grands-Jardins, making the combination of an explanatory guided tour and an ascent to a high viewpoint the most complete experience for understanding this geological phenomenon that remains the key to comprehending the entire regional landscape.
