The Codorus State Park Hidden Cove boat ramp is a concrete ramp that provides access to Codorus Creek, which flows into Lake Marburg. The ramp is approximately 24 feet wide and has a gradual slope, making it easy for boats to launch and retrieve. According to the Pennsylvania Fish and Boat Commission, boats of any size and type are permitted on Lake Marburg, including motorized and non-motorized watercraft. However, there is a 25 horsepower limit on outboard motors. The latest information available confirms that this boat ramp is open for public use year-round, weather permitting.
