The 180-acre Hyner Run State Park is in Chapman Township, Clinton County. The terrain of the park is generally level and occupies the small valley created by Hyner Run, with steep mountains on both sides. The park derives its name from Hyner Run, which flows through the park.
The 30-site camping area is open the second week in April and closes in late December. Each site has a level pad, picnic table and fire ring. Water and non-flush toilets with handwashing facilities are centrally located in the area.
From Renovo, take PA 120 east for six miles. Turn left onto Hyner Mountain Road (PA 1014) and travel two miles.
