That ersatz castle you see heading east on Lincoln Highway (Rte. 30) out of Lancaster is the headquarters for a 44-acre amusement park with a large water-play area and entertainment such as storytelling and theatrical high diving. There's a moderately wild roller coaster and a flume ride, but most of the 32 rides are perfect for young families. Special themed weekends include Happy Hauntings in mid-October and Winter Wonderland from late November through Christmas.
