When my family came to visit me I took them to a swimming lake I discovered. Mount Gretna is a park in the middle of nowhere. It is a popular place for swimming due to its small lake being redone with platforms in the middle of it that include a high dive, diving board, and swing. It is a great place to cool down in the summer heat and just 5 minutes away the Jigger Shop sits in the woods and offers amazing ice cream for a sweet treat.
