A short while from Philadelphia, out in the gentle rolling hills of Lancaster, Pennsylvania, is Dutch Wonderland, a sprawling theme park designed just for kids. Built in 1963, this family-friendly park has consistently been recognized as one of the best kid's parks on earth and it's not hard to see why — they boast a wide variety of fun live shows, Duke's Lagoon play area and 30 different rides, including roller coasters, splash flumes, virtual reality, bumper cars and slides.
