Although there are cheapER rates for families, this does not offer a budget day out, but at least it is a REAL treat! My children all loved it, and I expect a further visit soon as my youngest grandchild wants a visit with some of his cousins. As stated in the overview, this is THE zoo in the Northwest(Blackpool's is not at all bad but this is a higher league).
Obviously, there is a limited amount I can say without an exhaustive list of creatures: mammals, birds, amphibians, and reptiles. The amount of room per creature is far above average, and the zoo plays a major part in breeding and conservation programs.
If you want to interest a child, you need no words from me but good pictures, and these you can find on www.chesterzoo.org/cgi-bin/cgiwrap/sczooftp/photocomp.pl.
