This popular park, sitting just south of Rte 480 on Hwy 1, is one of the few in the province to offer a backcountry experience. From the campground, the Erin Mountain Trail (4.5km) winds through the forest and up to the 340m peak, where there are backcountry campsites and excellent views. Allow two hours for the climb.
Not far away are a couple of leisurely nature trails and a nice swimming area.
