Old Mill Stream Campground is owned by Dutch Wonderland Family Amusement Park. This is a very nice, clean, and well managed park.
There are over 160 shady private camping sites, from primitive to full hook-ups. They have paved roads, great bath houses and a nice country store. Also clean, well maintained restrooms, two laundromats and two dumping stations. There is also Free WiFi available throughout campground. On the negative side… this campground does NOT have a pool. I think they want you to walk next door and pay admission to the amusement park/water park.
