Due to seasonal extremes in temperature and the forces of gravity, large blocks of rock have broken away from the main face of the Niagara Escarpment. The gradual shifting downwards of these huge blocks has produced the crevice caves of the Collingwood-Blue Mountain area. The park’s range of microclimates supports interesting cliff face vegetation communities. Park Facilities and Activities The Duncan Escarpment is part of the Niagara Escarpment Parks System and the Niagara Biosphere Reserve.
No main entrance to park.
