Lusk Cave is in the Philippe Lake within Gatineau Park. It is an easy hike of 10km roundtrip along marked trails. The caves offer opportunities for spelunking for those who wish to.

When the Wisconsin Glacier melted about 12,500 years ago, water trapped under the melting glacier was forced into cracks in the rocks. The marble of Lusk Cave eroded more quickly than the surrounding rocks, causing a series of tunnels to form. Since then, Lusk Creek has continued to shape the cave.
