The park was opened by founder Jimmy Chipperfield on 17 April 1973 and hosted a few former circus animals. The park also had a dolphin area where the sea lion theatre is today, but it was a travelling show and the dolphins were later returned to Margate. The 1970s also saw the park develop a "boat safari", although it was later removed. A narrow-gauge railway through parts of the park was constructed by Severn Lamb in 1979.
