Karst-de-Saint-Elzéar Biodiversity Reserve (French: Réserve de biodiversité du Karst-de-Saint-Elzéar) is a biodiversity reserve located in Gaspésie–Îles-de-la-Madeleine, Quebec, Canada, around 15km (09miles) north of the town of Saint-Elzéar. It was established on June 20, 2005. It lies between latitudes 48°13’N and 48°19’N and between longitudes 65°17’W and 65°25’W. The elevation of the reserve lies at between 135m (443feet) and 605m (1,985feet).[1]
Within the reserve, seven caves have been discovered, although only one of them (grotte de Saint-Elzéar) is open to the public. It is the only reserve to conserve a karst.[2]
The cave is always 4C, whatever the time of year. It is 200m (700feet) long and 35m (115feet) deep. It is estimated to be around 230,000 years old, making it one of the oldest caves in Quebec.
