Mono Cliffs contains a significant section of the Niagara Escarpment, including crevice caves, an upland limestone plain, and talus slopes. The park features two prominent masses of rock, separated by erosion from the main rock body. When this occurs, the resultant feature is called an outlier. Botanists have noted that the local vegetation includes a particularly rich diversity of ferns. This park is part of the Niagara Escarpment Parks System, and the Niagara Escarpment Biosphere Reserve. The park offers parking lots, toilets, and trails for hiking. The natural features in the park are fragile.
