The European bison at Parc Animalier de Sainte-Croix reside in a vast nature reserve, sharing their habitat with Przewalski's horses. Visitors can observe these majestic animals by embarking on the Wild Expedition safari train, which traverses the expansive conservatory area.

The park is actively involved in conservation efforts, participating in numerous European breeding and reintroduction programs aimed at preserving endangered species. Since its establishment in 1980, Sainte-Croix has contributed to the release of over 50 animals into their natural habitats, underscoring its commitment to wildlife preservation.
