Located on the southern edge of the Niagara Escarpment, the park is a jumble of small but steep hills ("short hills") and valleys created by the last ice age. The effect was only compounded when the Twelve Mile Creek cut through the sedimentary deposits and glacial till.
The park contains six-side trails including the Bruce Trail and several waterfalls, it has a nice mix of both dense forests and open meadows, with meandering creeks and gentle hills that offer good hiking conditions.
