If you are expecting to see large cats roaming a sweeping vista you will be disappointed as the site (despite the largeness of Oregon) is relatively small and the majority of the cats are viewed in their enclosures.
However, if you want to learn about big cats and the challenges they face in the wild, how they can be trained and the breeding programs that GCWP get involved in, then you will have a worthwile visit.
Be sure to allow enough time (a couple of hours) to go on the guided tour as whilst you can visit the front area of the site on your own, this misses a lot of the action and you will miss out on the very knowledgable commentary (and from the childrens point of view hopefully the chance to stroke one of the inhabitants).
As grown ups we came away with the impression that places like GCWP will aid awareness of the decline of large felines in the wild and hopefully this was absorbed by the kids. If not, they still got to see a wide range of cats up close and luckly got the see the Cat Man himself (go on the tour, they will explain!) get a kiss from a large male lion!
