Park Alerts ( 7 Alerts )

  • Seasons and Hours: Contrary to the information on Google, Pennsylvania state parks are open every day of the year. Day use areas close at dusk. Park offices are open specific hours. Pools, beaches, and campgrounds are open specific seasons.

  • Drone Restrictions: To protect park resources, limit conflict with other park users, and avoid safety and privacy liabilities, unmanned aerial vehicles (UAV), remotely piloted vehicles (RPV) or unmanned aircraft systems (UAS), all commonly referred to as DRONES, are only permitted on designated flying fields in six remote controlled airfield parks (Beltsville, Benjamin Rush, Hillman, Lackawanna, Prompton, and Tuscarora). Drones are only permitted in other PA State Parks in very limited circumstances which require a special use permit.

  • Be advised that the section of McConnells Mill Road is closed between the intersections of Rim Road and Mt. Hope Furnace Road.  This section of the township roadway is not within the park boundaries, but will affect the recommended route from the Old Mill to Hells Hollow.  A detour, utilizing Rim Rd. and Wilson Rd. is in place.  The road closure is expected to occur for several years. 

  • General Firewood Quarantine: Pennsylvania Department of Agriculture has enacted a quarantine order for untreated firewood of any kind coming into the state. Any firewood brought into the state must be kiln dried, heat treated, fumigated, and/or USDA Certified.

    To protect the high quality and native character of our State Parks from exotic invasive species DCNR highly encourages all visitors to:

    • burn/buy locally cut firewood (within 25 miles)

    • BURN ALL firewood brought from another area. Do not leave it. Do not take it with you.

    • Encourage friends and neighbors not to move firewood

    • Do not remove firewood from a Spotted Lanternfly Quarantine Area. Contact the PA Department of Agriculture, www.agriculture.pa.gov and search on the keyword Spotted Lantern Fly for current quarantine information.

  • The operation of unmanned aircraft, such as drones, is a prohibited activity at McConnells Mill State Park.
  • Large buses, limousines, RV's, and other extended vehicles should not attempt to travel on the one way section of McConnells Mill Road between the intersections of Kennedy Road and Johnson Road. Due to large boulders and tight turns many vehicles of these type have sustained damage or been stuck along this section in the past. These types of vehicles should park at the Kildoo Day Use Area and visitors can either walk to the Grist Mill from there or arrange for more suitable transportation. Parking at the Grist Mill is extremely limited regardless of vehicle type.
  • All weddings at McConnells Mill need to be preapproved by calling the Moraine Park Office at 724-368-8811. This is necessary to ensure there are no conflicts with other events or programs and to limit unnecessary stress on your special day.
