Hiking at Codorus State Park
19 miles of trails
Although the park only has two “hiking only” trails, many miles of equestrian and mountain biking trails can also be hiked.
All trails are in hunting areas so visitors should wear fluorescent orange during hunting seasons.
Mary Ann Furnace Trail
3.5 miles, more difficult hiking
From the trailhead along Black Rock Road, the trail begins on a boardwalk through the wetlands of Black Rock Flats then climbs through a tall deciduous forest that borders old farm fields and comes to a Y.
The left trail eventually follows the shoreline of the lake. The right trail climbs to the top of the hill and gives a view of the campground. Both trails interconnect and connect to a spur that leads to the campground.
1.5 miles, easiest hiking
This trail follows the shoreline of Wildasin Flats.
The trail is primarily a single-track path that hugs the hillside, although a few trail sections ascend steep terrain and portions of the trail can be muddy.
The wetlands make this an excellent area for birding year round.
On a grassy knoll in the eastern part of the trail is Wildasin Cemetery, which has a tombstone dated 1722.
