This area of the Niagara Escarpment is well-known for its rock formation that from a distance resembles the profile of a lion. Some 400 million years old, these Cabot Head, Amabel, and Guelph formations of bedrock are exposed in the cliff face. Glacial outwash and eroded potholes lie on top of the escarpment, while mounds of rock debris overgrown with vegetation, lie along the bottom. The cliffs of the Niagara Escarpment, including those at Lion's Head, support one of the most ancient and least disturbed forest ecosystems in North America. Of particular interest are the ancient white cedars found along the cliff's edge. The park is also known for the presence of both nationally and provincially rare plant species. This park is part of the Niagara Escarpment Parks System, and the Niagara Escarpment Biosphere Reserve. The Bruce Trail passes through here. There are no visitor facilities. The purpose of this 526-hectare nature reserve is to protect the rock formation and the plants unique to the area. The area is best suited for hiking and nature appreciation. Visitors are asked to remember that the natural features are vulnerable and easily damaged.
